2010-07-26drm/i915: Use the correct scanout alignment for fbcon.Chris Wilson
This fixes a potential modesetting error during boot with plymouth on Broadwater and Crestline introduced with 9df47c. The framebuffer was hard-coding an alignment of 64K, but the modesetting code required the documented alignment of 128K. The result was that we would attempt to unbind the pinned fbcon buffer, triggering an ERROR and ultimately failing the mode change.

2010-07-26drm/i915: Make G4X-style PLL search more permissiveAdam Jackson
Fixes an Ironlake laptop with a 68.940MHz 1280x800 panel and 120MHz SSC reference clock. More generally, the 0.488% tolerance used before is just too tight to reliably find a PLL setting. I extracted the search algorithm and modified it to find the dot clocks with maximum error over the valid range for the given output type: http://people.freedesktop.org/~ajax/intel_g4x_find_best_pll.c This gave: Worst dotclock for Ironlake DAC refclk is 350000kHz (error 0.00571) Worst dotclock for Ironlake SL-LVDS refclk is 102321kHz (error 0.00524) Worst dotclock for Ironlake DL-LVDS refclk is 219642kHz (error 0.00488) Worst dotclock for Ironlake SL-LVDS SSC refclk is 84374kHz (error 0.00529) Worst dotclock for Ironlake DL-LVDS SSC refclk is 183035kHz (error 0.00488) Worst dotclock for G4X SDVO refclk is 267600kHz (error 0.00448) Worst dotclock for G4X HDMI refclk is 334400kHz (error 0.00478) Worst dotclock for G4X SL-LVDS refclk is 95571kHz (error 0.00449) Worst dotclock for G4X DL-LVDS refclk is 224000kHz (error 0.00510) Signed-off-by: Adam Jackson <ajax@redhat.com> Cc: stable@kernel.org Signed-off-by: Eric Anholt <eric@anholt.net>
2010-07-26drm/i915: Clear any existing dither mode prior to enabling spatial ditheringChris Wilson
We cannot the initial configuration set by the BIOS not to have a dither mode enabled which conflicts with our enabling the Spatial Temporal 1 dither mode for PCH. In particular, the BIOS may either enable temporal dithering or the Spatial Temporal 2 with the result that we enable pure temporal dithering. Temporal dithering looks bad and is perceived as a flicker.

2010-07-26drm/i915: handle shared framebuffers when flippingJesse Barnes

Gen3 chips have slightly different flip commands, and also contain a bit that indicates whether a "flip pending" interrupt means the flip has been queued or has been completed.

2010-06-18drm/i915: don't queue flips during a flip pending eventJesse Barnes
Hardware will set the flip pending ISR bit as soon as it receives the flip instruction, and (supposedly) clear it once the flip completes (e.g. at the next vblank). If we try to send down a flip instruction while the ISR bit is set, the hardware can become very confused, and we may never receive the corresponding flip pending interrupt, effectively hanging the chip.

2010-06-05drm/i915: Move non-phys cursors into the GTTChris Wilson
Cursors need to be in the GTT domain when being accessed by the GPU. Previously this was a fortuitous byproduct of userspace using pwrite() to upload the image data into the cursor. The redundant clflush was removed in commit 9b8c4a and so the image was no longer being flushed out of the caches into main memory. One could also devise a scenario where the cursor was rendered by the GPU, prior to being attached as the cursor, resulting in similar corruption due to the missing MI_FLUSH.

This reverts commit cfecde435dda78248d6fcdc424bed68d5db6be0b. The commit was first created as an attempt to fix LVDS initialiazation on Ironlake.

Subsequent testing has revealed that this commit has caused other regressions: * Change in VBlank interrupt frequency causing 60% 3D performance regression http://bugs.freedesktop.org/show_bug.cgi?id=27698 * Black screen on G45 http://bugs.freedesktop.org/show_bug.cgi?id=27733 So revert this buggy code for now to revisit later when we can fix actual bugs without causing these regressions.

2010-05-26drm/i915: Kill dangerous pending-flip debuggingChris Wilson
We can, by virtue of a vblank interrupt firing in the middle of setting up the unpin work (i.e. after we set the unpin_work field and before we write to the ringbuffer) enter intel_finish_page_flip() prior to receiving the pending flip notification. Therefore we can expect to hit intel_finish_page_flip() under normal circumstances without a pending flip and even without installing the pending_flip_obj. This is exacerbated by aperture thrashing whilst binding the framebuffer References: Bug 28079 - "glresize" causes kernel panic in intel_finish_page_flip. https://bugs.freedesktop.org/show_bug.cgi?id=28079 Reported-by: Nick Bowler <nbowler@draconx.ca> Signed-off-by: Chris Wilson <chris@chris-wilson.co.uk> Cc: Jesse Barnes <jbarnes@virtuousgeek.org> Cc: stable@kernel.org Reviewed-by: Jesse Barnes <jbarnes@virtuousgeek.org> Signed-off-by: Eric Anholt <eric@anholt.net>

Spatial dither is better than nothing, but ST is even better.

Easiest way to test this is by poking at PIPEACONF with intel_reg_write directly: % sudo intel_reg_write 0x70008 0xc0000040 # no dither % sudo intel_reg_write 0x70008 0xc0000050 # spatial % sudo intel_reg_write 0x70008 0xc0000054 # ST I notice it especially strongly in the relatively flat dark area in the top left. Closer than about 18" I can see a noticeable checkerboard pattern with plain spatial dithering. ST smooths that out; I can still tell that it's lacking color precision, but it's not offensive.

2010-04-12drm/i915: Add the support of memory self-refresh on IronlakeZhenyu Wang
Update the self-refresh watermark for display plane/cursor and enable the memory self-refresh on Ironlake. The watermark is also updated for the active display plane. More than 1W idle power is saved on one Ironlake laptop after enabling memory self-refresh. Signed-off-by: Zhao Yakui <yakui.zhao@intel.com> Signed-off-by: Zhenyu Wang <zhenyuw@linux.intel.com>
2010-04-12drm/i915: Move Pineview CxSR and watermark code into update_wm hook.Zhao Yakui
Previously, after setting up the Pineview CxSR state, i9xx_update_wm would get called and overwrite our state. BTW: We will disable the self-refresh and never enable it any more if we can't find the appropriate the latency on pineview plaftorm. In such case the update_wm callback will be NULL. The bitmask macro is also defined to access the corresponding fifo watermark register. Signed-off-by: Zhao Yakui <yakui.zhao@intel.com> Signed-off-by: Zhenyu Wang <zhenyuw@linux.intel.com>

2010-04-12drm/i915: Don't enable pipe/plane/VCO early (wait for DPMS on).Carl Worth
The existing code handling the DPMS ON event is much more careful to ensure that these registers are enabled according to strict sequencing requirements. Enabling these early in mode_set simply defeats that. Signed-off-by: Carl Worth <cworth@cworth.org> Signed-off-by: Eric Anholt <eric@anholt.net>
