This reverts commit dfadbbdb. Further upstream discussion between Marek and Thomas decided this wasn't fully baked and needed further work, so revert it before it hits mainline. Signed-off-by:

abrt files a lot of bug reports when users get GPU lockups, but there's not really enough context to do anything useful with them. Given the lack of GPU context being dumped, this patch removes the stack trace, so that abrt ignores the messages. Signed-off-by:

Misc fixes based on tests with an infoframe analyzer: - checksum *does* include header bytes - DIP enable & AVI infoframe are tied together in hw, so disable both and make sure AVI frames are enabled first - use every vsync flag for SPD frames to avoid reserved value in frequency field when enabling both AVI & SPD Fixes https://bugs.freedesktop.org/show_bug.cgi?id=40281.

The commit 47356eb6 introduced a mechanism to record the backlight level only at disabling time, but it also introduced a regression. Since intel_lvds_enable() may be called without disabling (e.g. intel_lvds_commit() calls it unconditionally), the backlight gets back to the last recorded value. For example, this happens when you dim the backlight, close the lid and open the lid, then the backlight suddenly goes to the brightest. This patch fixes the bug by recording the backlight level always when changed via intel_panel_set_backlight(). And, intel_panel_{enable|disable}_backlight() call the internal function not to update the recorded level wrongly. Cc: <stable@kernel.org> Signed-off-by:

Belongs in PCH enable instead. The duplication is worrying and the specs explicitly list transcoder select *after* actual PLL enable, which doesn't occur until later. Signed-off-by:

Jesse Barnes authored
At the point where we check, we can't do much about the failure, but it can aid debugging. Note that the auto-train override bit will be reset as part of normal mode setting with this patch if a pipe ever does get stuck, but that's consistent with the workaround for CPT provided by the hardware team. This patch helped catch the fact that the pipe wasn't running in the !composite sync FDI case on my IVB SDV, so has already shown to be useful. Signed-off-by:

Transcoder A will always use PLL A and transcoder B will use PLL B. But transcoder C could use either, so always mask the select bits off before or'ing in a new value. Reported-by:

Add two new fields to the intel_crtc struct for 3 pipe support: no_pll and use_pll_a. The no_pll field is only set on the 3rd pipe to indicate that it doesn't have a PLL of its own and so shouldn't try to write the main PLL regs. The use_pll_a field controls which PLL pipe 3 will share, A or B. The core code will try to share PLLs with whichever pipe has the same timings, rejecting the mode set if none is found. This means that pipe 3 must always be set after one of the other pipes has been configured with real PLL settings. Signed-off-by:

Add a couple of checks now that we're using the 3rd transcoder: 1) make sure the transcoder PLL enable bit is set for the transcoder in question 2) when checking actual PLL enable, use the selected PLL number rather than the transcoder number (they could be different now) Signed-off-by: -

Well almost anyway. IVB has 3 planes, pipes, transcoders, and FDI interfaces, but only 2 pipe PLLs. So two of the pipes must use the same pipe timings (e.g. 2 DP plus one other, or two HDMI with the same mode and one other, etc.). Signed-off-by:

I'm sending these out before some other patches because this should be a fairly simple one to get upstream and not require too much fuss (where the others may have some fuss).

[Description from: Daniel Vetter] I've just discussed this quickly with Chris on irc and it's probably best to just kill the list_empty early bailout. gpu_idle isn't a fastpath, so who cares. One candidate where we emit commands to the ring without adding anything onto these lists is e.g. pageflip. There are probably more. Signed-off-by:

We really don't want this to work in the general case; device drivers *shouldn't* care whether they are behind an IOMMU or not. But the integrated graphics is a special case, because the IOMMU and the GTT are all kind of smashed into one and generally horrifically buggy, so it's reasonable for the graphics driver to want to know when the IOMMU is active for the graphics hardware.

To work around a hardware issue, we have to submit IOTLB flushes while the graphics engine is idle. The graphics driver will (we hope) go to great lengths to ensure that it gets that right on the affected chipset(s)... so let's not screw it over by deferring the unmap and doing it later. That wouldn't be very helpful. Signed-off-by:

For the !HAVE_ATOMIC_IOMAP case the stub functions did not call pagefault_disable/_enable. The i915 driver relies on the map actually being atomic, otherwise it can deadlock with it's own pagefault handler in the gtt pwrite fastpath. This is exercised by gem_mmap_gtt from the intel-gpu-toosl gem testsuite. v2: Chris Wilson noted the lack of an include.
