maintainerPATCH 5/52 ALSA: hda/hdmi: let new platforms assign the pcm slot dynamically
In reply to Greg Kroah-HartmanFrom: Hui Wang <[email protected]>
[ Upstream commit 13046370c4d143b629adc1a51659a8a6497fbbe6 ]
If the platform set the dyn_pcm_assign to true, it will call hdmi_find_pcm_slot() to find a pcm slot when hdmi/dp monitor is connected and need to create a pcm.
So far only intel_hsw_common_init() and patch_nvhdmi() set the dyn_pcm_assign to true, here we let tgl platforms assign the pcm slot dynamically first, if the driver runs for a period of time and there is no regression reported, we could set no_fixed_assgin to true in the intel_hsw_common_init(), and then set it to true in the patch_nvhdmi().
This change comes from the discussion between Takashi and Kai Vehmanen. Please refer to:

Nvidia HDA HW expects infoframe data bytes order same for both HDMI and DP i.e infoframe data starts from 5th bytes offset. As dp infoframe structure has 4th byte as valid infoframe data, use hdmi infoframe structure for nvidia dp infoframe to match HW behvaior.

What happens is the following:
1) The cleaner kthread tries to start a transaction to delete an unused block group, but the metadata reservation can not be satisfied right away, so a reservation ticket is created and it starts the async metadata reclaim task (fs_info->async_reclaim_work);
2) Writeback for all the filler inodes with an i_size of 2K starts (generic/562 creates a lot of 2K files with the goal of filling metadata space). We try to create an inline extent for them, but we fail when trying to insert the inline extent with -ENOSPC (at cow_file_range_inline()) - since this is not critical, we fallback to non-inline mode (back to cow_file_range()), reserve extents, create extent maps and create the ordered extents;
3) An unmount starts, enters close_ctree();
4) The async reclaim task is flushing stuff, entering the flush states one by one, until it reaches RUN_DELAYED_IPUTS. There it runs all current delayed iputs.
After running the delayed iputs and before calling btrfs_wait_on_delayed_iputs(), one or more ordered extents complete, and btrfs_add_delayed_iput() is called for each one through btrfs_finish_ordered_io() -> btrfs_put_ordered_extent(). This results in bumping fs_info->nr_delayed_iputs from 0 to some positive value.
So the async reclaim task blocks at btrfs_wait_on_delayed_iputs() waiting for fs_info->nr_delayed_iputs to become 0;
5) The current transaction is committed by the transaction kthread, we then start unpinning extents and end up calling btrfs_try_granting_tickets() through unpin_extent_range(), since we released some space. This results in satisfying the ticket created by the cleaner kthread at step 1, waking up the cleaner kthread;
6) At close_ctree() we ask the cleaner kthread to park;
7) The cleaner kthread starts the transaction, deletes the unused block group, and then calls kthread_should_park(), which returns true, so it parks. And at this point we have the delayed iputs added by the completion of the ordered extents still pending;
8) Then later at close_ctree(), when we call:
cancel_work_sync(&fs_info->async_reclaim_work);
We hang forever, since the cleaner was parked and no one else can run delayed iputs after that, while the reclaim task is waiting for the remaining delayed iputs to be completed.
Fix this by waiting for all ordered extents to complete and running the delayed iputs before attempting to stop the async reclaim tasks. Note that we can not wait for ordered extents with btrfs_wait_ordered_roots() (or other similar functions) because that waits for the BTRFS_ORDERED_COMPLETE flag to be set on an ordered extent, but the delayed iput is added after that, when doing the final btrfs_put_ordered_extent(). So instead wait for the work queues used for executing ordered extent completion to be empty, which works because we do the final put on an ordered extent at btrfs_finish_ordered_io() (while we are in the unmount context).

Sink only devices do not have any source capabilities, so the driver should not warn about that. Also DRP (Dual Role Power) capable devices, such as USB Type-C docking stations, do not return any source capabilities unless they are plugged to a power supply themselves.

maintainerPATCH 12/52 thunderbolt: Explicitly reset plug events delay back to USB4 spec value
In reply to Greg Kroah-HartmanFrom: Mario Limonciello <[email protected]>
commit 31f87f705b3c1635345d8e8a493697099b43e508 upstream.
If any software has interacted with the USB4 registers before the Linux USB4 CM runs, it may have modified the plug events delay. It has been observed that if this value too large, it's possible that hotplugged devices will negotiate a fallback mode instead in Linux.
To prevent this, explicitly align the plug events delay with the USB4 spec value of 10ms.

maintainerPATCH 14/52 Input: snvs_pwrkey - fix SNVS_HPVIDR1 register address
In reply to Greg Kroah-HartmanFrom: Sebastian Krzyszkowiak <[email protected]>
commit e62563db857f81d75c5726a35bc0180bed6d1540 upstream.
Both i.MX6 and i.MX8 reference manuals list 0xBF8 as SNVS_HPVIDR1 (chapters 57.9 and 6.4.5 respectively).
Without this, trying to read the revision number results in 0 on all revisions, causing the i.MX6 quirk to apply on all platforms, which in turn causes the driver to synthesise power button release events instead of passing the real one as they happen even on platforms like i.MX8 where that's not wanted.

maintainerPATCH 15/52 clk: ingenic-tcu: Properly enable registers before accessing timers
In reply to Greg Kroah-HartmanFrom: Aidan MacDonald <[email protected]>
commit 6726d552a6912e88cf63fe2bda87b2efa0efc7d0 upstream.
Access to registers is guarded by ingenic_tcu_{enable,disable}_regs() so the stop bit can be cleared before accessing a timer channel, but those functions did not clear the stop bit on SoCs with a global TCU clock gate.
Testing on the X1000 has revealed that the stop bits must be cleared _and_ the global TCU clock must be ungated to access timer registers. This appears to be the norm on Ingenic SoCs, and is specified in the documentation for the X1000 and numerous JZ47xx SoCs.
If the stop bit isn't cleared, register writes don't take effect and the system can be left in a broken state, eg. the watchdog timer may not run.
The bug probably went unnoticed because stop bits are zeroed when the SoC is reset, and the kernel does not set them unless a timer gets disabled at runtime. However, it is possible that a bootloader or a previous kernel (if using kexec) leaves the stop bits set and we should not rely on them being cleared.
Fixing this is easy: have ingenic_tcu_{enable,disable}_regs() always clear the stop bit, regardless of the presence of a global TCU gate.

maintainerPATCH 19/52 powerpc/64s/radix: dont need to broadcast IPI for radix pmd collapse flush
In reply to Greg Kroah-HartmanFrom: Yang Shi <[email protected]>
commit bedf03416913d88c796288f9dca109a53608c745 upstream.
The IPI broadcast is used to serialize against fast-GUP, but fast-GUP will move to use RCU instead of disabling local interrupts in fast-GUP. Using an IPI is the old-styled way of serializing against fast-GUP although it still works as expected now.
And fast-GUP now fixed the potential race with THP collapse by checking whether PMD is changed or not. So IPI broadcast in radix pmd collapse flush is not necessary anymore. But it is still needed for hash TLB.

maintainerPATCH 20/52 libata: add ATA_HORKAGE_NOLPM for Pioneer BDR-207M and BDR-205
In reply to Greg Kroah-HartmanFrom: Niklas Cassel <[email protected]>
commit ea08aec7e77bfd6599489ec430f9f859ab84575a upstream.
Commit 1527f69204fe ("ata: ahci: Add Green Sardine vendor ID as board_ahci_mobile") added an explicit entry for AMD Green Sardine AHCI controller using the board_ahci_mobile configuration (this configuration has later been renamed to board_ahci_low_power).
The board_ahci_low_power configuration enables support for low power modes.
This explicit entry takes precedence over the generic AHCI controller entry, which does not enable support for low power modes.
Therefore, when commit 1527f69204fe ("ata: ahci: Add Green Sardine vendor ID as board_ahci_mobile") was backported to stable kernels, it make some Pioneer optical drives, which was working perfectly fine before the commit was backported, stop working.
The real problem is that the Pioneer optical drives do not handle low power modes correctly. If these optical drives would have been tested on another AHCI controller using the board_ahci_low_power configuration, this issue would have been detected earlier.
Unfortunately, the board_ahci_low_power configuration is only used in less than 15% of the total AHCI controller entries, so many devices have never been tested with an AHCI controller with low power modes.

maintainerPATCH 21/52 mmc: moxart: fix 4-bit bus width and remove 8-bit bus width
In reply to Greg Kroah-HartmanFrom: Sergei Antonov <[email protected]>
commit 35ca91d1338ae158f6dcc0de5d1e86197924ffda upstream.
According to the datasheet [1] at page 377, 4-bit bus width is turned on by bit 2 of the Bus Width Register. Thus the current bitmask is wrong: define BUS_WIDTH_4 BIT(1)
BIT(1) does not work but BIT(2) works. This has been verified on real MOXA hardware with FTSDC010 controller revision 1_6_0.
The corrected value of BUS_WIDTH_4 mask collides with: define BUS_WIDTH_8 BIT(2). Additionally, 8-bit bus width mode isn't supported according to the datasheet, so let's remove the corresponding code.

maintainerPATCH 22/52 mmc: hsq: Fix data stomping during mmc recovery
In reply to Greg Kroah-HartmanFrom: Wenchao Chen <[email protected]>
commit e7afa79a3b35a27a046a2139f8b20bd6b98155c2 upstream.
The block device uses multiple queues to access emmc. There will be up to 3 requests in the hsq of the host. The current code will check whether there is a request doing recovery before entering the queue, but it will not check whether there is a request when the lock is issued. The request is in recovery mode. If there is a request in recovery, then a read and write request is initiated at this time, and the conflict between the request and the recovery request will cause the data to be trampled.

maintainerPATCH 23/52 mm/page_alloc: fix race condition between build_all_zonelists and page allocation
In reply to Greg Kroah-HartmanFrom: Mel Gorman <[email protected]>
commit 3d36424b3b5850bd92f3e89b953a430d7cfc88ef upstream.
Patrick Daly reported the following problem;
NODE_DATA(nid)->node_zonelists[ZONELIST_FALLBACK] - before offline operation [0] - ZONE_MOVABLE [1] - ZONE_NORMAL [2] - NULL For a GFP_KERNEL allocation, alloc_pages_slowpath() will save the offset of ZONE_NORMAL in ac->preferred_zoneref. If a concurrent memory_offline operation removes the last page from ZONE_MOVABLE, build_all_zonelists() & build_zonerefs_node() will update node_zonelists as shown below. Only populated zones are added. NODE_DATA(nid)->node_zonelists[ZONELIST_FALLBACK] - after offline operation [0] - ZONE_NORMAL [1] - NULL [2] - NULL
The race is simple -- page allocation could be in progress when a memory hot-remove operation triggers a zonelist rebuild that removes zones. The allocation request will still have a valid ac->preferred_zoneref that is now pointing to NULL and triggers an OOM kill.
This problem probably always existed but may be slightly easier to trigger due to 6aa303defb74 ("mm, vmscan: only allocate and reclaim from zones with pages managed by the buddy allocator") which distinguishes between zones that are completely unpopulated versus zones that have valid pages not managed by the buddy allocator (e.g. reserved, memblock, ballooning etc). Memory hotplug had multiple stages with timing considerations around managed/present page updates, the zonelist rebuild and the zone span updates. As David Hildenbrand puts it
memory offlining adjusts managed+present pages of the zone essentially in one go. If after the adjustments, the zone is no longer populated (present==0), we rebuild the zone lists.
Once that's done, we try shrinking the zone (start+spanned pages) -- which results in zone_start_pfn == 0 if there are no more pages. That happens *after* rebuilding the zonelists via remove_pfn_range_from_zone().
The only requirement to fix the race is that a page allocation request identifies when a zonelist rebuild has happened since the allocation request started and no page has yet been allocated. Use a seqlock_t to track zonelist updates with a lockless read-side of the zonelist and protecting the rebuild and update of the counter with a spinlock.

maintainerPATCH 24/52 mm: prevent page_frag_alloc() from corrupting the memory
In reply to Greg Kroah-HartmanFrom: Maurizio Lombardi <[email protected]>
commit dac22531bbd4af2426c4e29e05594415ccfa365d upstream.
A number of drivers call page_frag_alloc() with a fragment's size > PAGE_SIZE.
In low memory conditions, __page_frag_cache_refill() may fail the order 3 cache allocation and fall back to order 0; In this case, the cache will be smaller than the fragment, causing memory corruptions.
Prevent this from happening by checking if the newly allocated cache is large enough for the fragment; if not, the allocation will fail and page_frag_alloc() will return NULL.

maintainerPATCH 25/52 mm/migrate_device.c: flush TLB while holding PTL
In reply to Greg Kroah-HartmanFrom: Alistair Popple <[email protected]>
commit 60bae73708963de4a17231077285bd9ff2f41c44 upstream.
When clearing a PTE the TLB should be flushed whilst still holding the PTL to avoid a potential race with madvise/munmap/etc. For example consider the following sequence:
CPU0 CPU1
---- ----
migrate_vma_collect_pmd()
pte_unmap_unlock()
madvise(MADV_DONTNEED)
-> zap_pte_range() pte_offset_map_lock()
[ PTE not present, TLB not flushed ] pte_unmap_unlock()
[ page is still accessible via stale TLB ]
flush_tlb_range()
In this case the page may still be accessed via the stale TLB entry after madvise returns. Fix this by flushing the TLB while holding the PTL.

maintainerPATCH 28/52 media: rkvdec: Disable H.264 error detection
In reply to Greg Kroah-HartmanFrom: Nicolas Dufresne <[email protected]>
commit 3a99c4474112f49a5459933d8758614002ca0ddc upstream.
Quite often, the HW get stuck in error condition if a stream error was detected. As documented, the HW should stop immediately and self reset. There is likely a problem or a miss-understanding of the self reset mechanism, as unless we make a long pause, the next command will then report an error even if there is no error in it.
Disabling error detection fixes the issue, and let the decoder continue after an error. This patch is safe for backport into older kernels.

maintainerPATCH 29/52 swiotlb: max mapping size takes min align mask into account
In reply to Greg Kroah-HartmanFrom: Tianyu Lan <[email protected]>
commit 82806744fd7dde603b64c151eeddaa4ee62193fd upstream.
swiotlb_find_slots() skips slots according to io tlb aligned mask calculated from min aligned mask and original physical address offset. This affects max mapping size. The mapping size can't achieve the IO_TLB_SEGSIZE * IO_TLB_SIZE when original offset is non-zero. This will cause system boot up failure in Hyper-V Isolation VM where swiotlb force is enabled. Scsi layer use return value of dma_max_mapping_size() to set max segment size and it finally calls swiotlb_max_mapping_size(). Hyper-V storage driver sets min align mask to 4k - 1. Scsi layer may pass 256k length of request buffer with 0~4k offset and Hyper-V storage driver can't get swiotlb bounce buffer via DMA API. Swiotlb_find_slots() can't find 256k length bounce buffer with offset. Make swiotlb_max_mapping _size() take min align mask into account.

maintainerPATCH 30/52 scsi: hisi_sas: Revert "scsi: hisi_sas: Limit max hw sectors for v3 HW"
In reply to Greg Kroah-HartmanFrom: Yu Kuai <[email protected]>
This reverts commit 24cd0b9bfdff126c066032b0d40ab0962d35e777.
1) commit 4e89dce72521 ("iommu/iova: Retry from last rb tree node if iova search fails") tries to fix that iova allocation can fail while there are still free space available. This is not backported to 5.10 stable.
2) commit fce54ed02757 ("scsi: hisi_sas: Limit max hw sectors for v3 HW") fix the performance regression introduced by 1), however, this is just a temporary solution and will cause io performance regression because it limit max io size to PAGE_SIZE * 32(128k for 4k page_size).
3) John Garry posted a patchset to fix the problem.
4) The temporary solution is reverted.
It's weird that the patch in 2) is backported to 5.10 stable alone, while the right thing to do is to backport them all together.

Errors from debugfs are intended to be non-fatal, and should not prevent the driver from probing.
Since debugfs file creation is treated as infallible, move it below the parts of the probe function that can fail. This prevents an error elsewhere in the probe function from causing the file to leak. Do the same for the call to of_platform_populate().
Finally, checkpatch suggests an octal literal for the file permissions.

maintainerPATCH 39/52 Revert "drm: bridge: analogix/dp: add panel prepare/unprepare in suspend/resume time"
In reply to Greg Kroah-HartmanFrom: Brian Norris <[email protected]>
[ Upstream commit cc62d98bd56d45de4531844ca23913a15136c05b ]
This reverts commit 211f276ed3d96e964d2d1106a198c7f4a4b3f4c0.
For quite some time, core DRM helpers already ensure that any relevant connectors/CRTCs/etc. are disabled, as well as their associated components (e.g., bridges) when suspending the system. Thus, analogix_dp_bridge_{enable,disable}() already get called, which in turn call drm_panel_{prepare,unprepare}(). This makes these drm_panel_*() calls redundant.
Besides redundancy, there are a few problems with this handling:
(1) drm_panel_{prepare,unprepare}() are *not* reference-counted APIs and are not in general designed to be handled by multiple callers -- although some panel drivers have a coarse 'prepared' flag that mitigates some damage, at least. So at a minimum this is redundant and confusing, but in some cases, this could be actively harmful.
(2) The error-handling is a bit non-standard. We ignored errors in suspend(), but handled errors in resume(). And recently, people noticed that the clk handling is unbalanced in error paths, and getting *that* right is not actually trivial, given the current way errors are mostly ignored.
(3) In the particular way analogix_dp_{suspend,resume}() get used (e.g., in rockchip_dp_*(), as a late/early callback), we don't necessarily have a proper PM relationship between the DP/bridge device and the panel device. So while the DP bridge gets resumed, the panel's parent device (e.g., platform_device) may still be suspended, and so any prepare() calls may fail.
So remove the superfluous, possibly-harmful suspend()/resume() handling of panel state.

maintainerPATCH 45/52 nvme: Fix IOC_PR_CLEAR and IOC_PR_RELEASE ioctls for nvme devices
In reply to Greg Kroah-HartmanFrom: Michael Kelley <[email protected]>
[ Upstream commit c292a337d0e45a292c301e3cd51c35aa0ae91e95 ]
The IOC_PR_CLEAR and IOC_PR_RELEASE ioctls are non-functional on NVMe devices because the nvme_pr_clear() and nvme_pr_release() functions set the IEKEY field incorrectly. The IEKEY field should be set only when the key is zero (i.e, not specified). The current code does it backwards.
Furthermore, the NVMe spec describes the persistent reservation "clear" function as an option on the reservation release command. The current implementation of nvme_pr_clear() erroneously uses the reservation register command.
Fix these errors. Note that NVMe version 1.3 and later specify that setting the IEKEY field will return an error of Invalid Field in Command. The fix will set IEKEY when the key is zero, which is appropriate as these ioctls consider a zero key to be "unspecified", and the intention of the spec change is to require a valid key.
Tested on a version 1.4 PCI NVMe device in an Azure VM.

In reply to Greg Kroah-HartmanFrom: Junxiao Chang <[email protected]>
[ Upstream commit 49725ffc15fc4e9fae68c55b691fd25168cbe5c1 ]
This commit fixes DMA engine reset timeout issue in suspend/resume with ADLink I-Pi SMARC Plus board which dmesg shows:
...
[ 54.678271] PM: suspend exit [ 54.754066] intel-eth-pci 0000:00:1d.2 enp0s29f2: PHY [stmmac-3:01] driver [Maxlinear Ethernet GPY215B] (irq=POLL) [ 54.755808] intel-eth-pci 0000:00:1d.2 enp0s29f2: Register MEM_TYPE_PAGE_POOL RxQ-0 ...

...
The issue is related with serdes which impacts clock. There is serdes in ADLink I-Pi SMARC board ethernet controller. Please refer to commit b9663b7ca6ff78 ("net: stmmac: Enable SERDES power up/down sequence") for detial. When issue is reproduced, DMA engine clock is not ready because serdes is not powered up.
To reproduce DMA engine reset timeout issue with hardware which has serdes in GBE controller, install Ubuntu. In Ubuntu GUI, click "Power Off/Log Out" -> "Suspend" menu, it disables network interface, then goes to sleep mode. When it wakes up, it enables network interface again. Stmmac driver is called in this way:
1. stmmac_release: Stop network interface. In this function, it disables DMA engine and network interface;
2. stmmac_suspend: It is called in kernel suspend flow. But because network interface has been disabled(netif_running(ndev) is false), it does nothing and returns directly;
3. System goes into S3 or S0ix state. Some time later, system is waken up by keyboard or mouse;
4. stmmac_resume: It does nothing because network interface has been disabled;
5. stmmac_open: It is called to enable network interace again. DMA engine is initialized in this API, but serdes is not power on so there will be DMA engine reset timeout issue.
Similarly, serdes powerdown should be added in stmmac_release. Network interface might be disabled by cmd "ifconfig eth0 down", DMA engine, phy and mac have been disabled in ndo_stop callback, serdes should be powered down as well. It doesn't make sense that serdes is on while other components have been turned off.
If ethernet interface is in enabled state(netif_running(ndev) is true) before suspend/resume, the issue couldn't be reproduced because serdes could be powered up in stmmac_resume.
Because serdes_powerup is added in stmmac_open, it doesn't need to be called in probe function.

In reply to Greg Kroah-HartmanFrom: Han Xu <[email protected]>
[ Upstream commit b1ff1bfe81e763420afd5f3f25f0b3cbfd97055c ]
There is no dedicate parent clock for QSPI so SET_RATE_PARENT flag should not be used. For instance, the default parent clock for QSPI is pll2_bus, which is also the parent clock for quite a few modules, such as MMDC, once GPMI NAND set clock rate for EDO5 mode can cause system hang due to pll2_bus rate changed.

maintainerPATCH 49/52 clk: iproc: Do not rely on node name for correct PLL setup
In reply to Greg Kroah-HartmanFrom: Florian Fainelli <[email protected]>
[ Upstream commit 1b24a132eba7a1c19475ba2510ec1c00af3ff914 ]
After commit 31fd9b79dc58 ("ARM: dts: BCM5301X: update CRU block description") a warning from clk-iproc-pll.c was generated due to a duplicate PLL name as well as the console stopped working. Upon closer inspection it became clear that iproc_pll_clk_setup() used the Device Tree node unit name as an unique identifier as well as a parent name to parent all clocks under the PLL.
BCM5301X was the first platform on which that got noticed because of the DT node unit name renaming but the same assumptions hold true for any user of the iproc_pll_clk_setup() function.
The first 'clock-output-names' property is always guaranteed to be unique as well as providing the actual desired PLL clock name, so we utilize that to register the PLL and as a parent name of all children clock.

maintainerPATCH 51/52 x86/alternative: Fix race in try_get_desc()
In reply to Greg Kroah-HartmanFrom: Nadav Amit <[email protected]>
commit efd608fa7403ba106412b437f873929e2c862e28 upstream.
I encountered some occasional crashes of poke_int3_handler() when kprobes are set, while accessing desc->vec.
The text poke mechanism claims to have an RCU-like behavior, but it does not appear that there is any quiescent state to ensure that nobody holds reference to desc. As a result, the following race appears to be possible, which can lead to memory corruption.
CPU0 CPU1

[ notice that desc is on

arch_atomic_inc_not_zero(&desc->refs)

Fix this issue with small backportable patch. Instead of trying to make RCU-like behavior for bp_desc, just eliminate the unnecessary level of indirection of bp_desc, and hold the whole descriptor as a global. Anyhow, there is only a single descriptor at any given moment.

maintainerPATCH 52/52 ALSA: hda/hdmi: fix warning about PCM count when used with SOF
In reply to Greg Kroah-HartmanFrom: Kai Vehmanen <[email protected]>
commit c74193787b2f683751a67603fb5f15c7584f355f upstream.
With commit 13046370c4d1 ("ALSA: hda/hdmi: let new platforms assign the pcm slot dynamically"), old behaviour to consider the HDA pin number, when choosing PCM to assign, was dropped.
Build on this change and limit the number of PCMs created to number of converters (= maximum number of concurrent display/receivers) when "mst_no_extra_pcms" and "dyn_pcm_no_legacy" quirks are both set.
Fix the check in hdmi_find_pcm_slot() to ensure only spec->pcm_used entries are considered in the search. Elsewhere in the driver spec->pcm_used is already checked properly.
Doing this avoids following warning at SOF driver probe for multiple machine drivers:
[ 112.425297] sof_sdw sof_sdw: hda_dsp_hdmi_build_controls: no PCM in topology for HDMI converter 4 [ 112.425298] sof_sdw sof_sdw: hda_dsp_hdmi_build_controls: no PCM in topology for HDMI converter 5 [ 112.425299] sof_sdw sof_sdw: hda_dsp_hdmi_build_controls: no
PCM in topology for HDMI converter 6
