We accidentally point both cfgcr registers for the second shared DPLL to the same location in i915_reg.h. This results in a lot of hw pipe state mismatches whenever we try to do a modeset that requires allocating the DPLL to a CRTC: [drm:intel_pipe_config_compare [i915]] *ERROR* mismatch in dpll_hw_state.cfgcr1 (expected 0x80000168, found 0x000004a5) [drm:intel_pipe_config_compare [i915]] *ERROR* mismatch in base.adjusted_mode.crtc_clock (expected 108000, found 49500) [drm:intel_pipe_config_compare [i915]] *ERROR* mismatch in port_clock (expected 108000, found 49500) This usually ends up causing blank monitors, since the DPLL never can get set to the right clock.

RC6 setup is shared between BIOS and Driver. BIOS sets up subset of RC6 setup registers. If those are not setup Driver should not enable RC6. For implementing this, driver can check RC_CTRL0 and RC_CTRL1 values to know if BIOS has enabled HW/SW RC6. This will also enable user to control RC6 using BIOS settings alone. RC6 related instability can be avoided by disabling via BIOS settings till driver fixes it. v2: Had placed logic in gen8 function by mistake. Fixed it. Ensuring RPM is not enabled in case BIOS disabled RC6. v3: Need to disable RPM if RC6 is disabled due to BIOS settings. (Daniel) Runtime PM enabling happens before gen9_enable_rc6. Moved the updation of enable_rc6 parameter in intel_uncore_sanitize. v4: Added elaborate check for BIOS RC6 setup. Prepared check_pctx for bxt. (Imre) v5: Caching reserved stolen base and size in the driver private data. Reorganized RC6 setup check. Moved from gen9_enable_rc6 to intel_uncore_sanitize.

The recent introduction of a new caller of dev_priv->fbc.deactivate() is a good example of why we need unexport those functions. Anything outside intel_fbc.c should only call the functions exported by intel_fbc.c, so in order to enforce that, kill the function pointers stored inside dev_priv->fbc and replace them with functions that can't be called from outside intel_fbc.c. This should make it much harder for new code to call these functions from outside intel_fbc.c.

WaIncreaseDefaultTLBEntries increases the number of TLB entries available for GPGPU workloads and gives significant ( > 10% ) performance gain for some OCL benchmarks. Put this in a new function that can be a place for workarounds that are GT related but not required per ring. This function is called on driver load and also after a reset and on resume, so it is safe for workarounds that get clobbered in these situations. This function currently has just this one workaround. v2: This was originally split into 3 patches but following review feedback was squashed into 1. I have not incorporated some style comments from Chris Wilson as I felt that after defining and intialising a temporary variable and then adding an additional if block to only write the register if the temporary variable had been set, this didn't really give a net gain. v3: Resending in the hope that BAT will run v4: Change subject line to trigger BAT (please!)

commit 033908ae Author: Dave Gordon <david.s.gordon@intel.com> Date: Thu Dec 10 18:51:23 2015 +0000 drm/i915: mark GEM object pages dirty when mapped & written by the CPU introduced a check into i915_gem_object_get_dirty_pages() that returned a NULL pointer when called with a bad object, one that was not backed by shmemfs. This WARN was too strict as we can work on all struct page backed objects, and resulted in a WARN + GPF for existing userspace. In order to differentiate the various types of objects, add a new flags field to the i915_gem_object_ops struct to describe their capabilities, with the first flag being whether the object has struct pages. v2: Drop silly const before an integer in the structure declaration.

Due to our lack of two-step watermark programming, our driver has historically pretended that the cursor plane is always on for the purpose of watermark calculations; this helps avoid serious flickering when the cursor turns off/on (e.g., when the user moves the mouse pointer to a different screen). That workaround was accidentally dropped as we started working toward atomic watermark updates. Since we still aren't quite there yet with two-stage updates, we need to resurrect the workaround and treat the cursor as always active. v2: Tweak cursor width calculations slightly to more closely match the logic we used before the atomic overhaul began.

In commit bfb9faab8 we added a workaround for some BXT BIOS that fail to properly initialize the DDI_A_4_LANES bit of the control register (4 lanes is the only valid configuration on BXT since there is no DDI E to share with). A recent patch added some additional checks on this register bit before the workaround gets applied; this breaks eDP on BXT in some settings. Some minor code shuffling is all we need to restore the workaround.

Our attempts save/restore panel power state in i915_suspend.c are causing unclaimed register warnings on BXT since the registers for this platform differ from older platforms. The big hammer suspend/resume shouldn't be necessary for PP since the connector/encoder hooks should already handle this. In theory we could remove this for all platforms, but in practice it's likely that would cause some regressions since older platforms with LVDS may have incomplete PP handling. For now we'll leave the PCH save/restore alone and change the non-PCH branch to only operate on gen <= 4 so that BXT and future platforms aren't included. v2: Typo fix: s/||/&&/ v3: Change non-PCH condition to a gen <= 4 test rather than listing VLV/CHV/BXT as specific platforms to exclude; should be more future-proof as we add new platforms.

While we are calling intel_dp_aux_transfer() with msg->size=0 whenever msg->buffer is NULL, passing NULL to memcpy() is undefined according to the ISO C standard. I haven't found any notes about this in the GNU C's or the kernel's documentation of the function and can't imagine what it would do with the NULL ptr. To better document this use of the parameters it still make sense to add an explicit check for this to the code.

Unfortunately we don't know all panels and platforms out there and we found internal prototypes without VBT proper set but where only link in standby worked well. So, before enable PSR by default let's instrument the PSR parameter in a way that we can identify different panels out there that might require or work better with link standby mode. It is also useful to say that for backward compatibility I'm not changing the meaning of this flag. So "0" still means disabled and "1" means enabled with full support and maximum power savings. v2: Use positive value instead of negative for different operation mode as suggested by Daniel. v3: As Paulo suggested use 2 to force link standby and 3 to force link fully on. Also split the link_standby introduction in a separated patch. v4: Use DRM_ERROR for link off request on platforms that don't support and Remove the quirk promise.

Link standby support has been deprecated with 'commit 89251b17 ("drm/i915: PSR: deprecate link_standby support for core platforms.")' The reason for that is that main link in full off offers more power savings and on HSW and BDW implementations on source side had known bugs with link standby. However that same HSD report only mentions BDW and HSW and tells that a fix was going to new platforms. Since on Skylake link standby didn't cause the bad blank flickering screens seen on HSW and BDW let's respect VBT again for this and future platforms.

Current code not just block link_standby for non DDI platforms but also block PSR from work on other ports B/C/D/E. So, besides change any behaviour let's just fix the mess a bit here and reuse HSW check to block the other ports and reduce the second if only to link stadnby request.

When we stop the sink CRC calculation we wait a while until the counter is reset to zero and return -ETIMEDOUT. However the sink crc was calculated already by this point so we just ignore this return at the main function. So, let's also ignore the message and put it as a debug message instead of an error one. The message might still be useful when debuging test failures so we could be able to know something was not going so well with sink crc stop. v2: Improve log message.

The FBC fixes we've been doing in the last months required a lot of refactor, so functions that were once big and called from different spots are now small and called only once. IMHO now it's better to just move the contents of these functions to their only callers since this reduces the number of indirections while reading the code. While at it, also improve the related comments a little bit.

We already make sure we run intel_fbc_update_update during modesets and page flips, and this function takes care of deactivating FBC, so it shouldn't be possible for us to reach the condition we check at intel_fbc_work_fn. So instead of grabbing framebuffer references and adding a lot of code to track when we need to free them, just don't track anything at all since we shouldn't need to. v2: Rebase.
