2010-08-21drm/i915: Remove the conflicting BUG_ON()Chris Wilson
We now attempt to free "active" objects following a GPU hang as either the GPU will be reset or the hang is permenant. In either case, the GPU writes will not be flushed to main memory and it should be safe to return that memory back to the system. The BUG_ON(active) is thus overkill and can erroneously fire after a EIO. Signed-off-by: Chris Wilson <chris@chris-wilson.co.uk> Signed-off-by: Eric Anholt <eric@anholt.net>

Like on Sandybridge, disabling the DAC here when doing CRT load detect avoids forever hangs waiting on the hardware. test procedure on HP 2740p: boot with no VGA plugged in, start X, plug in VGA monitor (1280x1024) chvt 3 machine hangs waiting forever.

2010-08-21drm/i915: wait for actual vblank, not just 20msJesse Barnes
Waiting for a hard coded 20ms isn't always enough to make sure a vblank period has actually occurred, so add code to make sure we really have passed through a vblank period (or that the pipe is off when disabling). This prevents problems with mode setting and link training, and seems to fix a bug like https://bugs.freedesktop.org/show_bug.cgi?id=29278, but on an HP 8440p instead. Hopefully also fixes https://bugs.freedesktop.org/show_bug.cgi?id=29141. Signed-off-by: Jesse Barnes <jbarnes@virtuousgeek.org> Signed-off-by: Eric Anholt <eric@anholt.net>
2010-08-18drm/i915: make sure eDP PLL is enabled at the right timeJesse Barnes
We need to make sure the eDP PLL is enabled before the pipes or planes, so do it as part of the DP prepare mode set function. Signed-off-by: Jesse Barnes <jbarnes@virtuousgeek.org>
2010-08-18drm/i915: fix VGA plane disable for Ironlake+Jesse Barnes
We need to use I/O port instructions to access VGA registers on Ironlake+, and it doesn't hurt on other platforms, so switch the VGA plane disable function over to using them. Move it to init time as well while we're at it, no need to repeatedly disable the VGA plane with every mode set and DPMS event. Signed-off-by: Jesse Barnes <jbarnes@virtuousgeek.org>
2010-08-18drm/i915: eDP mode set sequence correctionsJesse Barnes
We should disable the panel first when shutting down an eDP link. And when turning one on, the panel needs to be enabled before link training or eDP I/O won't be enabled. Signed-off-by: Jesse Barnes <jbarnes@virtuousgeek.org>
2010-08-18drm/i915: add panel reset workaroundJesse Barnes
Ironlake requires that we clear the reset panel bit during power sequences and restore it afterwards. Uncondtionally add code to do that since it should be harmless on SNB+. Signed-off-by: Jesse Barnes <jbarnes@virtuousgeek.org>

2010-08-13Call acpi_video_register() in intel_opregion_init() failure pathDavid Woodhouse
If i915 opregion is present, the acpi_video driver doesn't register itself immediately; it defers that until the i915 opregion code is done. But if that *fails*, the acpi_video driver was never getting registered. And thus I have no backlight support on my Lenovo IdeaPad S10-3. Call acpi_video_register() on the failure path, and it works again.

2010-08-12drm: Remove count_lock for calling lastclose() after 58474713 (v2)Chris Wilson
When removing of the BKL the locking around lastclose() was rearranged and resulted in the holding of the open_count spinlock over the call into drm_lastclose(). The drivers were not ready for this path to be atomic - it may indeed involve long waits to release old objects and cleanup the GPU - and so we ended up scheduling whilst atomic.

2010-08-10vt/console: try harder to print output when panicingJesse Barnes
Jesse's initial patch commit said: "At panic time (i.e. when oops_in_progress is set) we should try a bit harder to update the screen and make sure output gets to the VT, since some drivers are capable of flipping back to it. So make sure we try to unblank and update the display if called from a panic context." I've enhanced this to add a flag to the vc that console layer can set to indicate they want this behaviour to occur. This also adds support to fbcon for that flag and adds an fb flag for drivers to indicate they want to use the support. It enables this for KMS drivers.

This is consistent with trying to access a filename that not exist within a directory which is a good analogy here.

2010-08-10drm: Fix support for PCI domainsBenjamin Herrenschmidt
(For some reason I thought that went in ages ago ...) This fixes support for PCI domains in what should hopefully be a backward compatible way along with a change to libdrm. When the interface version is set to 1.4, we assume userspace understands domains and the world is at peace. We thus pass proper domain numbers instead of 0 to userspace. The newer libdrm will then try 1.4 first, and fallback to 1.1, along with ignoring domains in the later case (well, except on alpha of course) Signed-off-by: Benjamin Herrenschmidt <benh@kernel.crashing.org> Signed-off-by: Dave Airlie <airlied@redhat.com>

2010-08-09drm/i915/sdvo: Only set is_lvds if we have a valid fixed mode.Chris Wilson
If we have failed to ascertain the fixed mode for the LVDS panel, then trust the pixel clock ranges reported for the connection when determing valid modes. This makes intel_sdvo_mode_valid() consistent with intel_lvds_mode_valid() which is also a no-op is there is no fixed mode defined. (Since the mode is both validated by SDVO and LVDS, why are checking against an LVDS fixed mode in SDVO...) By only defining is_lvds to be true when we actually have an LVDS output with a fixed mode, we avoid various potential NULL deferences where the assumption is made that all LVDS outputs have a fixed mode. References: Bug 29449 - [Q35] failure to read EDID/vbios for LVDS, no mode => no output https://bugs.freedesktop.org/show_bug.cgi?id=29449 The primary failure in this bug is not finding the EDID and determining the correct fixed panel mode.

2010-08-09drm/i915: Wake-up wait_request() from elapsed hang-check (v2)Chris Wilson
If our watchdog fires and we see that the GPU is idle, but that we are still waiting on an interrupt, forcibly wake-up the waiter. i915_do_wait_request() should not be racy, yet there are persistent reports that 945GM hangs whilst the GPU is idle. This implies that the hardware is not quite as coherent as the documentation claims - a write followed by a flush is supposed to be coherent in main memory before the flush is retired and the irq is emitted. This seems to be a sensible and elegant guard to force the wait to timeout. v2: Daniel Vetter pointed out that a warning would be useful to explain why the machine appeared to stall.

2010-08-09drm/i915: Only update i845/i865 CURBASE when disabled (v2)Chris Wilson
The i845 and i865 have a peculiarlity in that CURBASE is not the trigger for the vsync update of the cursor registers but instead the modification of that register is prohibited whilst the cursor is enabled. Reorder the write sequence for CURPOS, CURCNTR and CURBASE on i845 to i865 to match. v2: Remove the checks for i845/i865 from within i9xx_cursor_update() Signed-off-by: Chris Wilson <chris@chris-wilson.co.uk> Signed-off-by: Eric Anholt <eric@anholt.net>
