2013-09-24drm/i915: preserve pipe A quirk in i9xx_set_pipeconfDaniel Vetter1-0/+4
This regression has been introduced in commit 9f11a9e4e50006b615ba94722dfc33ced89664cf Author: Daniel Vetter <daniel.vetter@ffwll.ch> Date: Thu Jun 13 00:54:58 2013 +0200 drm/i915: set up PIPECONF explicitly for i9xx/vlv platforms Ville brough up the idea that this is just the pipe A quirk gone wrong. Note that after resume the bios might or might not have enabled pipe A already. We have a bit of magic to make sure that on resume we set up a decent mode for pipe A, but I fear if I just smash pipe A to always on we'd enable it in a bogus state and hang the hw. Hence the readback. v2: Clarify the logic a bit as suggested by Chris. Also amend the commit message to clarify why we don't unconditionally enable the pipe.

2013-09-24drm/i915/tv: clear adjusted_mode.flagsDaniel Vetter1-0/+8
The native TV encoder has it's own flags to adjust sync modes and enabled interlaced modes which are totally irrelevant for the adjusted mode. This worked out nicely since the input modes used by both the load detect code and reported in the ->get_modes callbacks all have no flags set, and we also don't fill out any of them in the ->get_config callback. This changed with the additional sanitation done with commit 2960bc9cceecb5d556ce1c07656a6609e2f7e8b0 Author: Imre Deak <imre.deak@intel.com> Date: Tue Jul 30 13:36:32 2013 +0300 drm/i915: make user mode sync polarity setting explicit sinc now the "no flags at all" state wouldn't fit through core code any more. So fix this up again by explicitly clearing the flags in the ->compute_config callback. Aside: We have zero checking in place to make sure that the requested mode is indeed the right input mode we want for the selected TV mode. So we'll happily fall over if userspace tries to pull us. But that's definitely work for a different patch series. So just add a FIXME comment for now.

2013-09-24drm/i915: Use a temporary va_list for two-pass string handlingChris Wilson1-2/+4
In commit edc3d8848dc9fe2a470316363dab8ef211d77e01 Author: Mika Kuoppala <mika.kuoppala@linux.intel.com> Date: Thu May 23 13:55:35 2013 +0300 drm/i915: avoid big kmallocs on reading error state we introduce a two-pass mechanism for splitting long strings being formatted into the error-state. The first pass finds the length, and the second pass emits the right portion of the string into the accumulation buffer. Unfortunately we use the same va_list for both passes, resulting in the second pass reading garbage off the end of the argument list. As the two passes are only used for boundaries between read() calls, the corruption is only rarely seen.

This is a partial revert of c6cf7777a32da874fabec4fd1c2a579f0ba4e4dd. We need to take into account the clk voltage dependencies of the board.

2013-09-19drm/fb-helper: don't sleep for screen unblank when an oops is in progressDaniel Vetter1-0/+8
Otherwise the system will burn even brighter and worse, leave the user wondering what's going on exactly. Since we already have a panic handler which will (try) to restore the entire fbdev console mode, we can just bail out. Inspired by a patch from Konstantin Khlebnikov. The callchain leading to this, cut&pasted from Konstantin's original patch: callstack: panic() bust_spinlocks(1) unblank_screen() vc->vc_sw->con_blank() fbcon_blank() fb_blank() info->fbops->fb_blank() drm_fb_helper_blank() drm_fb_helper_dpms() drm_modeset_lock_all() mutex_lock(&dev->mode_config.mutex) Note that the entire locking in the fb helper around panic/sysrq and kdbg is ... non-existant. So we have a decent change of blowing up everything. But since reworking this ties in with funny concepts like the fbdev notifier chain or the impressive things which happen around console_lock while oopsing, I'll leave that as an exercise for braver souls than me.

After a vmalloc failure in ttm_dma_tt_alloc_page_directory(), ttm_dma_tt_init() will call ttm_tt_destroy() to cleanup, and end up inside the driver's unpopulate() hook when populate() has never yet been called. On nouveau, the first issue to be hit because of this is that dma_address[] may be a NULL pointer. After working around this, ttm_pool_unpopulate() may potentially hit the same issue with the pages[] array. It seems to make more sense to avoid calling unpopulate on already unpopulated TTMs than to add checks to all the implementations.

2013-09-15drm/radeon: fix panel scaling with eDP and LVDS bridgesAlex Deucher1-3/+31
We were using the wrong set_properly callback so we always ended up with Full scaling even if something else (Center or Full aspect) was selected. Signed-off-by: Alex Deucher <alexander.deucher@amd.com> Cc: stable@vger.kernel.org
2013-09-15drm/radeon/dpm: rework auto performance level enableAlex Deucher11-47/+9
Calling force_performance_level() from set_power_state() doesn't work on some asics because the current power state pointer has not been properly updated at that point. Move the calls to force_performance_level() out of the asic specific set_power_state() functions and into the main power state sequence. Fixes dpm resume on SI.

2013-09-15drm/radeon/dpm/rs780: fix force_performance state for same sclksAlex Deucher1-2/+4
If the low and high sclks within a power state are the same, there no need to enable sclk scaling. Enabling sclk scaling can cause display stability issues on some boards. Signed-off-by: Alex Deucher <alexander.deucher@amd.com> Reviewed-by: Christian König <christian.koenig@amd.com>
2013-09-15drm/radeon/dpm/rs780: don't enable sclk scaling if not requiredAlex Deucher1-0/+3
If the low and high sclks are the same, there is no need to enable sclk scaling. This causes display stability issues on certain boards.

2013-09-15drm/radeon/dpm/rs780: add some sanity checking to sclk scalingAlex Deucher1-0/+6
Since the clock scaling is based on fb divider adjustments, make sure the other pll parameters are the same. Signed-off-by: Alex Deucher <alexander.deucher@amd.com> Reviewed-by: Christian König <christian.koenig@amd.com>
