PATCH v2 4/10 tegra: SMP support
In reply to konkers at android.comHi,
Minor nitpick, but if you're going to repost for other reasons it might be worth to address:

Looks like this whole file uses spaces instead of tabs. You have a few other places in the patchkit that does the same.

v3 cover tegra: tegra support
In reply to konkers at android.comThis is the 3rd and hopefully final version of initial support for the Tegra sub architecture. Assuming no major issues come up, I'll be submitting these patches (possibly minus the fb support) to linux-next later this week. Thanks to all who have given feedback on the previous versions.
git://android.git.kernel.org/kernel/tegra.git for-next
Cheers,
Erik
PATCH v3 1/11 tegra: initial tegra support
v2: Fixes from Mike Rapoport
- remove unused header files (mach/dma.h and mach/nand.h)
- remove tegra 1 references from Makefile.boot
v2: fixes from Russell King
- remove mach/io.h include from mach/iomap.h
- fix whitespace in Kconfig
v2: from Colin Cross
- fix invalid immediate in debug-macro.S
v3:
- allow selection of multiple boards

PATCH v3 3/11 tegra: Add clock support
From: Colin Cross <[email protected]>
v2: fixes from Russell King:
- include linux/io.h instead of asm/io.h
- fix whitespace in Kconfig
- Use spin_lock_init to initialize lock
- Return -ENOSYS instead of BUG for unimplemented clock ops
- Use proper return values in tegra2 clock ops
additional changes:
- Rename some clocks to match dev_ids
- add rate propagation
- add debugfs entries
- add support for clock listed in clk_lookup under multiple dev_ids
v3:
- Replace per-clock locking with global clock lock

Apologies for the incremental review. The wait_condition code above looks odd to me. Typically, we just test the return value of wait_event_interruptible_timeout to see whether it timed out (returns 0 if so). But I guess the above approach works as well.

I still didn't follow how tegra_fb_activate is using the -ETIMEDOUT return value from the wait, it seems like it is just ignored. You are also doing stuff like HZ/10 and you might prefer to use msecs_to_jiffies.

It seems to me like the timeout from wait_for_event isn't propagated back upwards. Maybe it isn't needed but the way the code handles this seems confusing to me.

tegra_fb_activateis using the-ETIMEDOUTreturn value from the wait, it seems like it is just ignored. You are also doing stuff like HZ/10 and you might prefer to usemsecs_to_jiffies.I was unclear above. I mean the following code:

tegra_fb_readl(tegra_fb, DC_CMD_STATE_CONTROL)& 3) {

ETIMEDOUT in tegra_fb_wait_for_event is detecting waiting on an interrupt that is not firing, and the loop in tegra_fb_activate is checking for the double-buffering bits to clear in a reasonable amount of time. The if check in the loop makes sure that if the frame interrupt is not occuring, the driver doesn't loop forever on the double-buffering bits.
I'll modify tegra_fb_activate to propagate the error code and use msecs_to_jiffies.
