LSPCON adapters in low-power state may ignore the first I2C write during TMDS output buffer enabling, resulting in a blank screen even with an otherwise enabled pipe. Fix this by reading back and validating the written value a few times. The problem was noticed on GLK machines with an onboard LSPCON adapter after entering/exiting DC5 power state. Doing an I2C read of the adapter ID as the first transaction - instead of the I2C write to enable the TMDS buffers - returns the correct value. Based on this we assume that the transaction itself is sent properly, it's only the adapter that is not ready for some reason to accept this first write after waking from low-power state. In my case the second I2C write attempt always succeeded.

Hardware understands the regamma LUT as a piecewise linear function, with points spaced exponentially along the range. We previously programmed the LUT for range [2^-10, 2^0). This causes (normalized) color values of 1 (=2^0) to miss the programmed LUT, and fall onto the end region. For DCE, the end region is extrapolated using a single (base, slope) pair, using the max y-value from the last point in the curve as base. This presents a problem, since this value affects all three color channels. Scaling down the intensity of say - the blue regamma curve - will not affect it's end region. This is especially noticiable when using RedShift. It scales down the blue and green channels, but leaves full-intensity colors unshifted. Therefore, extend the range to cover [2^-10, 2^1) by programming another hardware segment, containing only one point. That way, we won't be hitting the end region. Note that things are a bit different for DCN, since the end region can be set per-channel. Signed-off-by:

Two years ago I tried an AMD Radeon E8860 embedded GPU with the drm driver. The dmesg output included driver warnings about an invalid PCIe lane width. Tracking the problem back led to si_set_pcie_lane_width_in_smc(). The calculation of the lane widths via ATOM_PPLIB_PCIE_LINK_WIDTH_MASK and ATOM_PPLIB_PCIE_LINK_WIDTH_SHIFT macros did not increment the resulting value, per the comment in pptable.h ("lanes - 1"), and per usage elsewhere. Applying the increment silenced the warnings. The code has not changed since, so either my analysis was incorrect or the bug has gone unnoticed. Hence submitting this as an RFC.

The system sleep PM ops azx_suspend() and azx_resume() were previously called by vga_switcheroo, but commit 07f4f97d ("vga_switcheroo: Use device link for HDA controller") removed their invocation. Unfortunately the commit neglected to update the #ifdef surrounding the two functions, so if CONFIG_PM_SLEEP is *not* enabled but all three of CONFIG_PM, CONFIG_VGA_SWITCHEROO and CONFIG_SND_HDA_CODEC_HDMI *are* enabled, the compiler now emits the following warning: sound/pci/hda/hda_intel.c:1024:12: warning: 'azx_resume' defined but not used [-Wunused-function] static int azx_resume(struct device *dev) ^~~~~~~~~~ sound/pci/hda/hda_intel.c:989:12: warning: 'azx_suspend' defined but not used [-Wunused-function] static int azx_suspend(struct device *dev) ^~~~~~~~~~~ Silence by updating the #ifdef. Because the #ifdef block now uses the same condition as the one immediately succeeding it, the two blocks can be collapsed together, shaving off another two lines.

After commit dd9f31c7 Author: Imre Deak <imre.deak@intel.com> Date: Wed Aug 16 17:46:07 2017 +0300 drm/i915/gen9+: Set same power state before hibernation image save/restore during hibernation/suspend the power domain functionality got disabled, after which resume could leave it incorrectly disabled if the ACPI target state was S0 during suspend and i915 was not loaded by the loader kernel. This was caused by not considering if we resumed from hibernation as the condition for power domains reiniting. Fix this by simply tracking if we suspended power domains during system suspend and reinit power domains accordingly during resume. This will result in reiniting power domains always when resuming from hibernation, regardless of the platform and whether or not i915 is loaded by the loader kernel. The reason we didn't catch this earlier is that the enabled/disabled state of power domains during PMSG_FREEZE/PMSG_QUIESCE is platform and kernel config dependent: on my SKL the target state is S4 during PMSG_FREEZE and (with the driver loaded in the loader kernel) S0 during PMSG_QUIESCE. On the reporter's machine it's S0 during PMSG_FREEZE but (contrary to this) power domains are not initialized during PMSG_QUIESCE since i915 is not loaded in the loader kernel, or it's loaded but without the DMC firmware being available.
