Simplifies things because for all the infoframes we care about, we always send them on each vblank. Also, this gets rid of one of the hw specific functions mislabelled with the intel_ prefix - hsw will completely change how this works!

The principle of intel_mark_busy() is that we want to spot the transition of when the display engine is being used in order to bump powersaving modes and increase display clocks. As such it is only important when the display is changing, i.e. when rendering to the scanout or other sprite/plane, and these are characterised by being pinned. v2: Mark the whole device as busy on execbuffer and pageflips as well and rebase against dinq for the minor bug fix to be immediately applicable.

The registers are on the PCH, so use the PCH name instead of the CPU name. Also, the way this function is implemented is really only for CPT and PPT. For now, both functions have the same implementations: the next patch will fix ibx_write_infoframe.

Better safe than sorry. Currently we never change the frequency and use the same for every infoframe type, so the only way to reproduce a bug would be with the BIOS doing something.

Don't use intermediate variables, change the value of 'val' as we go through the function. The new style looks more similar to the rest of our code. IMHO, it's also easier to read and change.

Gen3+ is 13 bits (12:0), and on gen2 only 12 (11:0). For both the high bits are marked reserved, read-only so continue to mask them. Bit 31 is not reserved and has a meaning.

Backmerge of drm-next to resolve a few ugly conflicts and to get a few fixes from 3.4-rc6 (which drm-next has already merged). Note that this merge also restricts the stencil cache lra evict policy workaround to snb (as it should) - I had to frob the code anyway because the CM0_MASK_SHIFT define died in the masked bit cleanups. We need the backmerge to get Paulo Zanoni's infoframe regression fix for gm45 - further bugfixes from him touch the same area and would needlessly conflict.

Daniel prepared this branch with a back-merge as git was getting very confused about changes in intel_display.c
-
Daniel Vetter authored
Conflicts: drivers/gpu/drm/i915/intel_display.c Ok, this is a fun story of git totally messing things up. There /shouldn't/ be any conflict in here, because the fixes in -rc6 do only touch functions that have not been changed in -next. The offending commits in drm-next are 14415745..1fa61106 which simply move a few functions from intel_display.c to intel_pm.c. The problem seems to be that git diff gets completely confused: $ git diff 14415745..1fa61106 is a nice mess in intel_display.c, and the diff leaks into totally unrelated functions, whereas $git diff --minimal 14415745..1fa61106 is exactly what we want. Unfortunately there seems to be no way to teach similar smarts to the merge diff and conflict generation code, because with the minimal diff there really shouldn't be any conflicts. For added hilarity, every time something in that area changes the + and - lines in the diff move around like crazy, again resulting in new conflicts. So I fear this mess will stay with us for a little longer (and might result in another backmerge down the road). Signed-Off-by: Daniel Vetter <daniel.vetter@ffwll.ch>

verify_parent_transid needs to lock the extent range to make sure no IO is underway, and so it can safely clear the uptodate bits if our checks fail. But, a few callers are using it with spinlocks held. Most of the time, the generation numbers are going to match, and we don't want to switch to a blocking lock just for the error case. This adds an atomic flag to verify_parent_transid, and changes it to return EAGAIN if it needs to block to properly verifiy things. Signed-off-by: Chris Mason <chris.mason@oracle.com>

The test in pdc_console_tty_close '!tty->count' was always wrong because tty->count is decremented after tty->ops->close is called and thus can never be zero. Hence the 'then' branch was never executed and the timer never deleted. This did not matter until commit 5dd5bc40 ("TTY: pdc_cons, use tty_port"). There we needed to set TTY in tty_port to NULL, but this never happened due to the bug above. So change the test to really trigger at the last close by changing the condition to 'tty->count == 1'. Well, the driver should not touch tty->count at all. It should use tty_port->count and count open count there itself.

While trying to fix up gen4 gpu reset in commit f49f0586 Author: Kenneth Graunke <kenneth@whitecape.org> Date: Sat Sep 11 01:19:14 2010 -0700 drm/i915: Actually set the reset bit in i965_reset a little confusion about when wait_for times out has been introduced - wait for loops _until_ the condition is true. This fixes gpu reset on my gm45, testing with my hangman code shows that it's now fairly reliable - it only died after well over 100 reset cycles.

On gen4+ we don't reset the display unit, so resetting the complete modeset state should not be necessary. We can't do reset on gen3 anyway, which leaves us with gen2 reset: According to Chris Wilson, that doesn't work so great, so he suggested we just ignore that. If the need ever arrises, we can re-add it later on. Signed-Off-by: Daniel Vetter <daniel.vetter@ffwll.ch>
