v3 cover s390x/vfio-ccw: Channel Path Handling [QEMU]

Here is a new pass at the channel-path handling code for vfio-ccw, to take advantage of the corresponding kernel patches posted here:

https://lore.kernel.org/kvm/[email protected]/

Per the discussion in v2, I dropped the EIO-to-CC3 patch from the head of the series.

I also added a patch to refactor css_queue_crw(), so we can get a CRW queued with a fully-qualified CRW we get out of this region instead of extracting/recreating it.

Besides that, changes should be in the git notes for each patch.

v2: https://lore.kernel.org/qemu-devel/[email protected]/
v1: https://lore.kernel.org/qemu-devel/[email protected]/

PATCH v3 2/7 vfio-ccw: Refactor cleanup of regions

In reply to Eric Farman

While we're at it, add a g_free() for the async_cmd_region that is the last thing currently created. g_free() knows how to handle NULL pointers, so this makes it easier to remember what cleanups need to be performed when new regions are added.

PATCH v3 3/7 vfio-ccw: Add support for the schib region

In reply to Eric Farman

From: Farhan Ali <[email protected]>

The schib region can be used to obtain the latest SCHIB from the host passthrough subchannel. Since the guest SCHIB is virtualized, we currently only update the path related information so that the guest is aware of any path related changes when it issues the 'stsch' instruction.

Notes:
v1->v2:
- Remove silly variable intialization, and add a block comment, to css_do_stsch() [CH]
- Add a TODO statement to s390_ccw_store(), for myself to sort out while we go over kernel code more closely [CH/EF]
- In vfio_ccw_handle_store(),
- Set schib pointer once region is determined to be non-NULL [CH]
- Return cc=0 if pread() fails, and log an error [CH]

v0->v1: [EF]
- Change various incarnations of "update chp status" to "handle_store", to reflect the STSCH instruction that will drive this code
- Remove temporary variable for casting/testing purposes in s390_ccw_store(), and add a block comment of WHY its there.
- Add a few comments to vfio_ccw_handle_store()

PATCH v3 4/7 vfio-ccw: Add support for the crw region

In reply to Eric Farman

From: Farhan Ali <[email protected]>

The crw region can be used to obtain information about Channel Report Words (CRW) from vfio-ccw driver.

Currently only channel path related CRWs are passed to QEMU from vfio-ccw driver.

PATCH v3 6/7 s390x/css: Refactor the css_queue_crw() routine

In reply to Eric Farman

We have a use case (vfio-ccw) where a CRW is already built and ready to use. Rather than teasing out the components just to reassemble it later, let's rework this code so we can queue a fully-qualified CRW directly.

Yeah, I don't like it either. Just took it from the variable "crw_cont" in the original code, but it does seem more like a continuation. Since the "container" is something built in that routine, maybe the "add_to_queue" variant fits better.

Now that we actually pass something in, do we want to inform the caller whether the crw was queued or not?

Hrm... Well I guess we could use it to break out of our loop in patch
7. But for the existing callers of css_queue_crw(), it doesn't provide much value to anyone but css_generate_css_crws(). I'll poke at this a bit.

PATCH v3 7/7 vfio-ccw: Add support for the CRW irq

In reply to Eric Farman

From: Farhan Ali <[email protected]>

The CRW irq will be used by vfio-ccw to notify the userspace about any CRWs the userspace needs to handle. Let's add support for it.

Notes:
v2->v3:
- Remove "size==0" check in CRW notifier [CH]
- Remove intermediate rsc/erc variables, use css_queue_crw_cont() [CH]
- s/crw0/crw/ [CH]

v1->v2:
- Add a loop to continually read region while data is present, queueing CRWs as found [CH]

v0->v1: [EF]
- Check vcdev->crw_region before registering the irq, in case host kernel does not have matching support
- Split the refactoring changes to an earlier (new) patch (and don't remove the "num_irqs" check in the register routine, but adjust it to the check the input variable)
- Don't revert the cool vfio_set_irq_signaling() stuff
- Unregister CRW IRQ before IO IRQ in unrealize

Do you want to clear the notifier again at the end? If the kernel had queued more crws, it would have made the notifier pending again.
