2012-10-23drm/i915: VGA needs to be on pipe A on i830MDaniel Vetter1-1/+1
The bit doesn't stick, and the output is always cloned from pipe A, even when it's supposed to scan out from pipe B. Shuts up annoying warnings from the modeset-rework, too. I've noticed that with this patch we know get and unknown connection state since the code can't find a suitable pipe for load detection. But that beats the previous state of affairs, where it tried to use pipe B, actually used pipe A and concluded that something is connected (although it's the LVDS on pipe A and nothing on the VGA connector on pipe B). I've tried to make load detect work by remapping the pipe->planes stuff, so that crtc 0 will use pipe B and hence we still have something left for load-detect on pipe A. But alas, that upset the hw a bit. So there's still some things to figure out, but this here will at least paper over some of the problems.

2012-10-23drm/i915: fix overlay on i830MDaniel Vetter1-3/+11
The overlay on the i830M has a peculiar failure mode: It works the first time around after boot-up, but consistenly hangs the second time it's used. Chris Wilson has dug out a nice errata: "1.5.12 Clock Gating Disable for Display Register Address Offset: 06200h–06203h "Bit 3 Ovrunit Clock Gating Disable. 0 = Clock gating controlled by unit enabling logic 1 = Disable clock gating function DevALM Errata ALM049: Overlay Clock Gating Must be Disabled: Overlay & L2 Cache clock gating must be disabled in order to prevent device hangs when turning off overlay.SW must turn off Ovrunit clock gating (6200h) and L2 Cache clock gating (C8h)." Now I've nowhere found that 0xc8 register and hence couldn't apply the l2 cache workaround. But I've remembered that part of the magic that the OVERLAY_ON/OFF commands are supposed to do is to rearrange cache allocations so that the overlay scaler has some scratch space. And while pondering how that could explain the hang the 2nd time we enable the overlay, I've remembered that the old ums overlay code did _not_ issue the OVERLAY_OFF cmd. And indeed, disabling the OFF cmd results in the overlay working flawlessly, so I guess we can workaround the lack of the above workaround by simply never disabling the overlay engine once it's enabled. Note that we have the first part of the above w/a already implemented in i830_init_clock_gating - leave that as-is to avoid surprises. v2: Add a comment in the code.

2012-10-23drm/ttm: Fix a theoretical race in ttm_bo_cleanup_refs()Thomas Hellstrom1-8/+12
In theory, that function could release the lru lock between checking for bo on ddestroy list and a successful reserve if the bo was already reserved, and the function was called with waiting reserves allowed. However, all current reservers of a bo on the ddestroy list would atomically take the bo off the list after a successful reserve so this race should not have been hit, so no need to backport for stable. This patch also fixes a case found by Maarten Lankhorst where ttm_mem_evict_first called with no_wait_gpu would incorrectly spin waiting for bo idle if trying to evict a busy buffer that also sits on the ddestroy list.

So, from now on, this perliminary_hw_support module parameter shall be used by all upcoming platforms that are still under enabling.

2012-10-16Revert "drm/i915: Try harder to complete DP training pattern 1"Daniel Vetter1-5/+10
This reverts commit 2477367083b3eaa97f87993ab26627a02f350551. If (for whatever reason) the DP sink device never asks for the maximal voltage level, we never don't hit the check that should bail us out after 5 retries of the same voltage. Which leads to an endless loop in the DP link training code, which hangs the driver. Now some more DP link training experiments on eDP panels seem to indicate that our training algorithm isn't robust enough anyway and needs more work. Hence for 3.7-fixes, let's just revert the regressing commit instead of trying to apply more duct-tape.

2012-10-16DRM/i915: Restore sdvo_flags after dtd->mode->dtd Roundrtrip.Egbert Eich1-0/+8
For TV and LVDS encoders intel_sdvo_set_input_timings_for_mode() is called to pass a mode to the sdvo chip and retrieve a dtd containing information needed to calculate the adjusted_mode which is done by intel_sdvo_get_dtd_from_mode(). To set this adjusted_mode as input mode for the sdvo chip, a dtd is recalculated using intel_sdvo_get_mode_from_dtd(). During this round trip the sdvo_flags contained in the dtd obtained from the hardware are lost. Since these flags cannot be ignored in all cases this patch preserves and restores them.

The DPLL multipiler is set up in intel_display.c:i9xx_update_pll() called from i9xx_crtc_mode_set(). There the DPLL multiplier is adjusted so that the SDVO gets a sufficient bus clock. When cloning a CRTC between an SDVO driven encoder and the standard DAC the DAC setup code reseted the multiplier value to 1 thus undoing the correct setup. There is no need to touch the multiplier in the DAC setup code: the correct value (i.e. 1 in case no SDVO encoder is used) is set by i9xx_update_pll() already. A comment at the code suggested that this code is a left over from the days when there was no setup for clone modes.

Based on Dmitries work, but splitting the code into page directory and page table handling makes it far more readable and (hopefully) more reliable. Allocations of page tables are made from the SA on demand, that should still work fine since all page tables are of the same size. Also using the fact that allocations from the SA are mostly continuously (except for end of buffer wraps and under very high memory pressure) to group updates send to the chipset specific code into larger chunks. v3: mostly a rewrite of Dmitries previous patch. v4: fix some typos and coding style Signed-off-by: Dmitry Cherkasov <Dmitrii.Cherkasov@amd.com> Signed-off-by: Christian König <deathsimple@vodafone.de> Tested-by: Michel Dänzer <michel.daenzer@amd.com> Reviewed-by: Alex Deucher <alexander.deucher@amd.com> Signed-off-by: Alex Deucher <alexander.deucher@amd.com>
