The atomic version of intel_pre_plane_update did not check for HAS_GMCH_DISPLAY before calling intel_set_memory_cxsr(). While this doesn't cause any issues on its own (it will return without doing anything if the hardware doesn't have the required feature), the drm_wait_one_vblank() that is needed if memory self-refresh is disabled introduces an unnecessary delay in the suspend path. In cases where i915 is on the critical path it means that we slow down suspend by 16.8ms on platforms that don't need to disable memory self-refresh. Signed-off-by:

Apparently some CHV boards failed to hook up the port presence straps for HDMI ports as well (earlier we assumed this problem only affected eDP ports). So let's check the VBT in addition to the strap, and if either one claims that the port is present go ahead and register the relevant connector. While at it, change port D to register DP before HDMI as we do for ports B and C since commit 457c52d8 ("drm/i915: Only ignore eDP ports that are connected") Also print a debug message when we register a HDMI connector to aid in diagnosing missing/incorrect ports. We already had such a print for DP/eDP. v2: Improve the comment in the code a bit, note the port D change in the commit message Cc: Radoslav Duda <radosd@radosd.com> Tested-by:

When resetting and reloading the GuC, the GuC submission management code also needs to destroy and recreate the GuC client(s). Currently this is done by a separate call from the GuC loader, but really, it's just an internal detail of the submission code. So here we remove the call from the loader (which is too late, really, because the GuC has already been reloaded at this point) and put it into guc_submission_init() instead. This means that any preexisting client is destroyed *before* the GuC (re)load and then recreated after, iff the firmware was successfully loaded. If the GuC reload fails, we don't recreate the client, so fallback to execlists mode (if active) won't leak the client object (previously, the now-unusable client would have been left allocated, and leaked if the driver were unloaded).

The last stage of the GuC loader also sanitises the GuC submission settings, so should be called unconditionally (even on platforms without a GuC) to ensure consistent settings; in particular, this prevents any attempt to use GuC submission on GuCless platforms! Also fix error path handling and clarify DRM_INFO fallback message. Signed-off-by:

Fix the failure mode where the display appears split, or shifted about 2/3 of the screen, and the color components are cycled. Turns out we were missing the crucial BXT_DEFEATURE_DPI_FIFO_CTR bit in the EOT_DISABLE register. Per bspec, with the bit set, the "mipi_dpf_vblank_start" signal is asserted only when the complete frame is transferred in the DPHY line and also the DPI FIFO is flushed out at the end of each frame. The problem was mitigated by keeping the panel fitter enabled, but that only limited the issue to a shift of about 0..10 pixels. With the fix here, the panel fitter workaround does not seem to be needed at all. While at it, set BXT_DPHY_DEFEATURE_EN in EOT_DISABLE register which is also needed per the BXT DSI mode set sequence.

The VBT has these mysterious H/V image sizes as part of the display timings. Looking at some dumps those appear to be the physical dimensions in mm. Which makes sense since the timing descriptor matches the format used by EDID detailed timing descriptor, which defines these as "H/V Addressable Video Image Size in mm". So let's use that information from the panel fixed mode to get the physical dimensions for LVDS/eDP/DSI displays. And with that we can fill out the display_info so that userspace can get at it via GetConnector. v2: Use (hi<<8)|lo instead of broken (hi<<4)+lo Handle LVDS and eDP too Cc: Stephen Just <stephenjust@gmail.com> Tested-by:Stephen Just <stephenjust@gmail.com> Bugzilla: https://bugs.freedesktop.org/show_bug.cgi?id=96255Signed-off-by:

"drm/i915: Make unpin async" doesn't handle the unthrottled cursor updates correctly, leading to an apparent pin count leak. This is caught by the WARN_ON in i915_gem_object_do_pin which screams if we have more than DRM_I915_GEM_OBJECT_MAX_PIN_COUNT pins. Unfortuantely we can't just revert these two because this patch series came with a built-in bisect breakage in the form of temporarily removing the unthrottled cursor update hack for legacy cursor ioctl. Therefore there's no other option than to revert the entire pile :( There's one tiny conflict in intel_drv.h due to other patches, nothing serious. Normally I'd wait a bit longer with doing a maintainer revert, but since the minimal set of patches we need to revert (due to the bisect breakage) is so big, time is running out fast. And very soon (especially after a few attempts at fixing issues) it'll be really hard to revert things cleanly. Lessons learned: - Not a good idea to rush the review (done by someone fairly new to the area) and not make sure domain experts had a chance to read it. - Patches should be properly split up. I only looked at the two patches that should be reverted in detail, but both look like the mix up different things in one patch. - Patches really should have proper commit messages. Especially when doing more than one thing, and especially when touching critical and tricky core code. - Building a patch series and r-b stamping it when it has a built-in bisect breakage is not a good idea. - I also think we need to stop building up technical debt by postponing atomic igt testcases even longer. I think it's clear that there's enough corner cases in this beast that we really need to have the testcases _before_ the next step lands.

On Loading, GuC sets PM interrupts routing (bit 31) and clears ARAT expired interrupt (bit 9). Host turbo also updates this register in RPS flows. This patch ensures bit 31 and bit 9 setup by GuC persists. ARAT timer interrupt is needed in GuC for various features. It also facilitates halting GuC and hence achieving RC6. PM interrupt routing will not impact RPS interrupt reception by host as GuC will redirect them. This patch fixes igt test pm_rc6_residency that was failing with guc load/submission enabled.

Daniel Vetter pointed out that vga_switcheroo_client_probe_defer() could be needed by audio clients as well. To avoid mistakes when someone adds conditions for these in the future, constrain the single existing condition to VGA clients by checking for PCI_BASE_CLASS_DISPLAY. This encompasses both PCI_CLASS_DISPLAY_VGA as well as PCI_CLASS_DISPLAY_3D, which is used by some Nvidia Optimus GPUs. Any future checks for audio clients should then be constrained to PCI_BASE_CLASS_MULTIMEDIA. v6: Spun out from commit introducing vga_switcheroo_client_probe_defer() to keep it a pure refactoring change.

So far we've got one condition when DRM drivers need to defer probing on a dual GPU system and it's coded separately into each of the relevant drivers. As suggested by Daniel Vetter, deduplicate that code in the drivers and move it to a new vga_switcheroo helper. This yields better encapsulation of concepts and lets us add further checks in a central place. (The existing check pertains to pre-retina MacBook Pros and an additional check is expected to be needed for retinas.) One might be tempted to check deferred probing conditions in vga_switcheroo_register_client(), but this is usually called fairly late during driver load. The GPU is fully brought up and ready for switching at that point. On boot the ->probe hook is potentially called dozens of times until it finally succeeds, and each time we'd repeat bringup and teardown of the GPU, lengthening boot time considerably and cluttering logfiles. A separate helper is therefore needed which can be called right at the beginning of the ->probe hook. Note that amdgpu currently does not call this helper as the AMD GPUs built into MacBook Pros are only supported by radeon so far. v2: This helper could eventually be used by audio clients as well, so rephrase kerneldoc to refer to "client" instead of "GPU" and move the single existing check in an if block specific to PCI_CLASS_DISPLAY_VGA devices. Move documentation on that check from kerneldoc to a comment. (Daniel Vetter) v3: Mandate in kerneldoc that registration of client shall only happen after calling this helper. (Daniel Vetter) v4: Rebase on 412c8f7d ("drm/radeon: Return -EPROBE_DEFER when amdkfd not loaded") v5: Some Optimus GPUs use PCI_CLASS_DISPLAY_3D, make sure those are matched as well. (Emil Velikov) v6: The if-condition referring to PCI_BASE_CLASS_DISPLAY may be considered a functional change. Move to a separate commit to keep this a pure refactoring change.
