if no VBT is present, crt_ddc_bus will be left at 0, and cause us to use that for the GPIO register offset. That's never a valid register offset, so let the "undefined" value be 0 instead of -1. Signed-off-by:

In commit d2d9f232, the guard for a valid video mode was removed. This caused the regression: kernel crash during kms graphic boot on Intel GM4500 platform https://bugzilla.redhat.com/show_bug.cgi?id=540218 This patches changes the logic slightly not to rely on a coupled variable, but to just check whether the video_modes is valid before dereferencing.

When switching to interruptible sleeps in the overlay code, I've forgotten to recover from interruptions at one site. This resulted in the overlay still running when it should have been switched off. This in turn caused a hang on resume because it tried to disable the (not-running) overlay in preparation for the resume modeset.

HW guys have an evaluation about the impact about EOS, and say the impact is quite small, so they have removed EOS detection support. This patch removes EOS feature. revert commit 04302965 directly reverting it gives a hunk error, so please use this one. Signed-off-by:

20ms delay is quite big and the routine isn't called in atomic context. better use msleep to let other tasks run. This can reduce cpu time used by Xorg, so potentially boost boot. Signed-off-by:

In disable sequence, all output ports on PCH have to be disabled before PCH transcoder, but LVDS port was left always enabled. This one fixes that by disable LVDS port properly during pipe disable process, and resolved stability issue seen on Ironlake. Also move panel fitting disable time just after pipe disable to align with the spec. Signed-off-by:

The DPLL calculation logic for 9xx platform is changed in: commit 652c393a Author: Jesse Barnes <jbarnes@virtuousgeek.org> Date: Mon Aug 17 13:31:43 2009 -0700 drm/i915: add dynamic clock frequency control Maybe we will get the different M/N/P combination with that by using the previous dpll calculation logic. So restore the DPLL calculation logic for 9xx platform. Signed-off-by:

Enumerate the LVDS panel timing info entry list in VBT to check whether the LVDS downclock is found. If found, the downclock is also used to switch dynamically between low and high frequency for LVDS. Signed-off-by:
-
Zhao Yakui authored
If more than one mode with the same resolution defined in EDID has different refresh rate, it is thought that the downclock is found for LVDS. We will program the different FPx0/1 register so that we can select dynamically between the low and high frequency. On the g4x platform we will use the CxSR feature to switch the different refresh rate if the LVDS downclock feature is supported. Signed-off-by:

Execbufs involve quite a bit of payload, to the extent that cache misses show up in the profiles here, and a suspicion that some of those cachelines may get evicted and then reloaded in the subsequent copy. This is still abstracted like drm_calloc_large since we want to check for size overflow, and because we want to choose between kmalloc and vmalloc on the fly. cairo's interface for malloc-with-calloc's-args was used as the model.

Somehow the case for G33 got dropped while porting from ums code. This made a 400MHz chip into a 133MHz one which resulted in the unnecessary enabling of double wide pipe mode which in turn screwed up the overlay code. Nothing else (than the overlay code) seems to be affected. This fixes fdo.org bug #24835 Signed-off-by:

Create a /debug/dri/%d/i915_wedged file to display the current wedged status, and to enable setting that value. On an i965, this will also trigger a GPU reset. Useful in order to attempt to recover from some error conditions that are not currently caught by the automatic hang detection code. Signed-off-by:

Replace the DRM_DEBUG with DRM_DEBUG_DRIVER in generic i915 driver. Then the debug info can be obtained by adding the boot option of "drm.debug=0x02". At the same time the debug info in increase/decrease clock is also printed by using DRM_DEBUG_DRIVER instead of DRM_DEBUG_KMS. Signed-off-by:

At least for the common case of userspace ioctls. When doing a modeset operation, the wait is still uninterruptible. But considering that failing to turn off the overlay when switching off the crtc it's running on hangs the chip, it doesn't complicate matters _very_ much. There's just an unkillable X in addition to a black screen. BUG() about it and explain in the code. Signed-off-by:

Now that the cache flushing of the memory based overlay regs works, we can safely switch off the overlay. Beforehand it was only disabled (like in userspace). Signed-off-by:

This implements intel overlay support for kms via a device-specific ioctl. Thomas Hellstrom brought up the idea of a general ioctl (on dri-devel). We've reached the conclusion that such an infrastructure only makes sense when multiple kms overlay implementations exists, which atm don't (and it doesn't look like this is gonna change). Open issues: - Runs in sync with the gpu, i.e. unnecessary waiting. I've decided to wait on this because the hw tends to hang when changing something in this area. I left some dummy functions as infrastructure. - polyphase filtering uses a static table. - uses uninterruptible sleeps. Unfortunately the alternatives may unnecessarily wedged the hw if/when we timeout too early (and userspace only overloaded the batch buffers with stuff worth a few secs of gpu time). Changes since v1: - fix off-by-one misconception on my side. This fixes fullscreen playback. Changes since v2: - add underrun detection as spec'ed for i965. - flush caches properly, fixing visual corruptions. Changes since v4: - fix up cache flushing of overlay memory regs. - killed require_pipe_a logic - it hangs the chip. Tested-By: diego.abelenda@gmail.com (on a 865G) Signed-off-by:

This just waits until the hw passed the current ring position with cmd execution. This slightly changes the existing i915_wait_request function to make uninterruptible waiting possible - no point in returning to userspace while mucking around with the overlay, that piece of hw is just too fragile. Also replace a magic 0 with the symbolic constant (and kill the then superflous comment) while I was looking at the code. Signed-off-by:
