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. This should only help on situations with Y tiling + 90/270 rotation + 1 or 2 bpp or NV12. Cc: stable@vger.kernel.org Reviewed-by:

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." This means we should only do the +2 in case wm[0] == 0, not always. So split the sanitizing implementation from the WA implementation and fix the WA implementation. v2: Add Fixes tag (Maarten).

And use it to move knowledge about the SAGV-supporting platforms from the callers to the SAGV code. We'll add more platforms to intel_has_sagv(), so IMHO it makes more sense to move all this to a single function instead of patching all the callers every time we add SAGV support to a new platform. v2: Move I915_SAGV_NOT_CONTROLLED to the new function (Lyude).

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.

We really do need to be using the halved V fields. I had been confused by the code I was using as a reference because it stored halved vsync fields but not halved vdisplay, so it looked like I only needed to divide vdisplay by 2. This reverts part of Mario's timestamping fixes that prevented CRTC_HALVE_V from applying, and instead adjusts the timestamping code to not use the crtc field in that case. Fixes locking of 1920x1080x60i on my Dell 2408WFP. There are black bars on the top and bottom, but I suspect that might be an under/overscan flags problem as opposed to video timings.

On Pi0/1/2, we use an external GPIO line for hotplug detection, since the HDMI_HOTPLUG register isn't connected to anything. However, with the Pi3 the HPD GPIO line has moved off to a GPIO expander that will be tricky to get to (the firmware is constantly polling the expander using i2c0, so we'll need to coordinate with it).

Pre DCE4 hw doesn't have reliable pageflip completion interrupts, so instead polling for flip completion is used from within the vblank irq handler to complete page flips. This causes a race if pageflip ioctl is called close to vblank: 1. pageflip ioctl queues execution of radeon_flip_work_func. 2. vblank irq fires, radeon_crtc_handle_vblank checks for flip_status == FLIP_SUBMITTED finds none, no-ops. 3. radeon_flip_work_func runs inside vblank, decides to set flip_status == FLIP_SUBMITTED and programs the flip into hw. 4. hw executes flip immediately (because in vblank), but as 2 already happened, the flip completion routine only emits the flip completion event one refresh later -> wrong vblank count/timestamp for completion and no performance gain, as instead of delaying the flip until next vblank, we now delay the next flip by 1 refresh while waiting for the delayed flip completion event. Given we often don't gain anything due to this race, but lose precision, prevent the programmed flip from executing in vblank on pre DCE4 asics to avoid this race. On pre-AVIVO hw we can't program the hw for edge-triggered flips, they always execute anywhere in vblank. Therefore delay the actual flip programming until after vblank on pre-AVIVO. Reviewed-by:

Pre DCE4 hardware doesn't have (reliable) pageflip completion irqs, therefore we have to use the old polling method for flip completion handling in vblank irq. As vblank irqs fire a bit before start of vblank (when the linebuffer fifo read position reaches end of scanout), we have some fudge for flip completion handling in the last lines of active scanout. Old code assumed the threshold to be 99% of active scanout height, a ballpark estimate which worked ok. Since we know since a while how to calculate the actual threshold from linebuffer size, lets make use of it to get a more accurate threshold. This completion path is still prone to some races in corner cases, especially on pre-AVIVO hardware, so document them a bit better in the code comments. Acked-by:

There's no point in enabling PSR when the panel doesn't support it. This also avoids a problem when PSR gets enabled when a CRTC is being disabled, because sometimes in that situation the DSP_HOLD_VALID_INTR interrupt on which we wait will never arrive. This was observed on RK3288 with a panel without PSR (veyron-jaq Chromebook). It's very easy to reproduce by running the kms_rmfb test in IGT a few times.
