When we enable the per-register access mmiodebug, it is to detect which access is illegal. Reporting on earlier untraced access outside of the mmiodebug does not help debugging (as the suspicion is immediately put upon the current register which is not at fault)!

We were previously adding all the planes owned by the CRTC even when the ddb partitioning didn't change for them. As a consequence, a lot of functions were being called when we were just moving the cursor around the screen, such as skylake_update_primary_plane(). This was causing flickering on the primary plane when moving the cursor. I'm not 100% sure which operation caused the flickering, but we were writing to a lot of registers, so it could be any of these writes. With this patch, just moving the mouse won't add the primary plane to the commit since it won't trigger a change in DDB partitioning. v2: Use skl_ddb_entry_equal() (Lyude). v3: Change Reported-and-bisected-by: to Reported-by: for checkpatch Fixes: 05a76d3d ("drm/i915/skl: Ensure pipes with changed wms get added to the state") Bugzilla: https://bugs.freedesktop.org/show_bug.cgi?id=97888 Cc: Mike Lothian <mike@fireburn.co.uk> Cc: stable@vger.kernel.org Reported-by:

DPLL_SDVO_HIGH_SPEED must be set for SDVO/HDMI/DP, but nowhere is it forbidden to set it for LVDS/CRT as well. So let's also set it on CRT to make it possible to share the DPLL between HDMI and CRT. What that bit apparently does is enable the x5 clock to the port, which then pumps out the bits on both edges of the clock. The DAC doesn't need that clock since it's not pumping out bits, but I don't think it hurts to have the DPLL output that clock anyway. This is fairly important on IVB since it has only two DPLLs with three pipes. So trying to drive three or more PCH ports with three pipes is only possible when at least one of the DPLLs gets shared between two of the pipes. SNB doesn't really need to do this since it has only two pipes. It could be done to avoid enabling the second DPLL at all in certain cases, but I'm not sure that's such a huge win. So let's not do it for SNB, at least for now. On ILK it never makes sense as the DPLLs can't be shared. v2: Just always enable the high speed clock to keep things simple (Daniel) Beef up the commit message a bit (Daniel) Cc: Nick Yamane <nick.diego@gmail.com> Cc: Daniel Vetter <daniel.vetter@ffwll.ch> Cc: stable@vger.kernel.org Tested-by:Nick Yamane <nick.diego@gmail.com> Bugzilla: https://bugs.freedesktop.org/show_bug.cgi?id=97204Signed-off-by:

This should affect linear and X tiled planes on really small htotal cases. It doesn't seem to be a very feasible case, but let's implement it since it's on the specification and it's better to have it and never need than not have it and realize we needed it. Reviewed-by:

We forgot the "res_blocks += y_tile_minimum" that's described on step V of our documentation. Again, this should only affect the Y tiling cases. It looks like the relevant code was introduced in 0fda6568, but there's always the possibility that it matched our specification when it was introduced, and then the specification changed while the code stayed the same. So we can't really say this was a regression, but let's try to add a "Fixes" tag anyway to help backporting. v2: Try to add a "Fixes" tag (Maarten).

The confusing thing is that plane_blocks_per_line is listed as part of the method 2 calculation but is also used for other things. We calculated it in two different places and different ways: one inside skl_wm_method2() and the other inside skl_compute_plane_wm(). The skl_wm_method2() implementation is the one that matches the specification. With this patch we fix the skl_compute_plane_wm() calculation and just pass it as a parameter to skl_wm_method2(). We also take care to not modify the value of plane_bytes_per_line since we're going to rely on it having a correct value in later patches. This should affect the watermarks for Linear and Y-tiled. From my analysis, it looks like the two plane_blocks_per_line variables got out of sync on 0fda6568, but we can't really say that commit was a regression, it looks like just an incomplete fix. There's always the possibility that 0fda6568 matched our specification at that time, and then later the specification changed. v2: Try to add a "Fixes" tag (Maarten).

During watermarks calculations, this value is used in 3 different places. Only one of them was not using a hardcoded 4. Move the code up so everybody can benefit from the actual value.

Bspec says: "The mailbox response data may not account for memory read latency. If the mailbox response data for level 0 is 0us, add 2 microseconds to the result for each valid level."

And use it to move knowledge about the SAGV-supporting platforms from the callers to the SAGV code.

The plan is to introduce intel_has_sagv() and then use it to discover which platforms actually support it. I thought about keeping the functions with their current skl names, but found two problems: (i) skl_has_sagv() would become a very confusing name, and (ii) intel_atomic_commit_tail() doesn't seem to be calling any functions whose name start with a platform name, so the "intel_" naming scheme seems make more sense than the "firstplatorm_" naming scheme here.

We never remembered to set it (so it was zero), but this was not a problem in the past due to the way handled the hardware registers. Unfortunately we changed how we set the hardware and forgot to set intel_crtc->dspaddr_offset. This started to reflect on a few kms_frontbuffer_tracking subtests that relied on page flips with CRTCs that don't point to the x:0,y:0 coordinates of the frontbuffer. After the page flip the CRTC was showing the x:0,y:0 coordinate of the frontbuffer instead of x:500,y:500. This problem is present even if we don't enable FBC or PSR. While trying to bisect it I realized that the first bad commit actually just gives me a black screen for the mentioned tests instead of showing the wrong x:0,y:0 offsets. A few commits later the black screen problem goes away and we get to the point where the code is today, but I'll consider the black screen as the first bad commit since it's the point where the IGT subtests start to fail.

Ever since I started working on FBC I was already aware that FBC can really amplify the FIFO underrun symptoms. On systems where FIFO underruns were harmless error messages, enabling FBC would cause the underruns to give black screens. We recently tried to enable FBC on Haswell and got reports of a system that would hang after some hours of uptime, and the first bad commit was the one that enabled FBC. We also observed that this system had FIFO underrun error messages on its dmesg. Although we don't have any evidence that fixing the underruns would solve the bug and make FBC work properly on this machine, IMHO it's better if we minimize the amount of possible problems by just giving up FBC whenever we detect an underrun. v2: New version, different implementation and commit message. v3: Clarify the fact that we run from an IRQ handler (Chris). v4: Also add the underrun_detected check at can_choose() to avoid misleading dmesg messages (DK). v5: Fix Engrish, use READ_ONCE on the unlocked read (Chris).

DP MST provides the capability to send multiple video and audio streams through a single port. This requires the API's between i915 and audio drivers to distinguish between multiple audio capable displays that can be connected to a port. Currently only the port identity is shared in the APIs. This patch adds support for MST with an additional parameter 'int pipe'. The existing parameter 'port' does not change it's meaning. pipe = MST : display pipe that the stream originates from Non-MST : -1 Affected APIs: struct i915_audio_component_ops - int (*sync_audio_rate)(struct device *, int port, int rate); + int (*sync_audio_rate)(struct device *, int port, int pipe, + int rate); - int (*get_eld)(struct device *, int port, bool *enabled, - unsigned char *buf, int max_bytes); + int (*get_eld)(struct device *, int port, int pipe, + bool *enabled, unsigned char *buf, int max_bytes); struct i915_audio_component_audio_ops - void (*pin_eld_notify)(void *audio_ptr, int port); + void (*pin_eld_notify)(void *audio_ptr, int port, int pipe); This patch makes dummy changes in the audio drivers (thanks Libin) for build to succeed. The audio side drivers will send the right 'pipe' values for MST in patches that will follow. v2: Renamed the new API parameter from 'dev_id' to 'pipe'.

With DP MST, a digital_port can carry more than one audio stream. Hence, more than one audio_connector needs to be attached to intel_digital_port in such cases. However, each stream is associated with an unique encoder. So, instead of creating an array of audio_connectors per port, move audio_connector from struct intel_digital_port to struct intel_encoder. This also simplifies access to the right audio_connector from codec functions in intel_audio.c that receive intel_encoder. v2: Removed locals that are not needed anymore. v3: No code change except for minor change in context.

There is a disparity in the context image saved to disk and our own bookkeeping - that is we presume the RING_HEAD and RING_TAIL match our stored ce->ring->tail value. However, as we emit WA_TAIL_DWORDS into the ring but may not tell the GPU about them, the GPU may be lagging behind our bookkeeping. Upon hibernation we do not save stolen pages, presuming that their contents are volatile. This means that although we start writing into the ring at tail, the GPU starts executing from its HEAD and there may be some garbage in between and so the GPU promptly hangs upon resume.

To keep lockdep silent, we need to take struct_mutex for the shrinker even though we know that we are the only user during the freeze.

Following commit 821ed7df ("drm/i915: Update reset path to fix incomplete requests") we no longer mark the context as lost on reset as we keep the requests (and contexts) alive. However, RPS remains reset and we need to restore the current state to match the in-flight requests.
