2022-03-02drm/i915/xehp: Define context scheduling attributes in lrc descriptorMatt Roper
In Dual Context mode the EUs are shared between render and compute command streamers. The hardware provides a field in the lrc descriptor to indicate the prioritization of the thread dispatch associated to the corresponding context. The context priority is set to 'low' at creation time and relies on the existing context priority to set it to low/normal/high.

2022-03-02drm/i915/xehp: CCS should use RCS setup functionsMatt Roper
The compute engine handles the same commands the render engine can (except 3D pipeline), so it makes sense that CCS is more similar to RCS than non-render engines. The CCS context state (lrc) is also similar to the render one, so reuse it. Note that the compute engine has its own CTX_R_PWR_CLK_STATE register. In order to avoid having multiple RCS && CCS checks, add the following engine flag: - I915_ENGINE_HAS_RCS_REG_STATE - use the render (larger) reg state ctx.

Add execlists and GuC interrupts for compute CS into existing IRQ handlers.

2022-03-02drm/i915/xehp: CCS shares the render reset domainMatt Roper
The reset domain is shared between render and all compute engines, so resetting one will affect the others. Note: Before performing a reset on an RCS or CCS engine, the GuC will attempt to preempt-to-idle the other non-hung RCS/CCS engines to avoid impacting other clients (since some shared modules will be reset). If other engines are executing non-preemptable workloads, the impact is unavoidable and some work may be lost.

But if the command in previous transfer is requested with length 0, it's a no-op to anx7625 since it can't process this command. anx7625 requires the last command to be read command with length > 0.

2022-03-01drm/i915/guc: Initialize GuC submission locks and queues earlyDaniele Ceraolo Spurio
Move initialization of submission-related spinlock, lists and workers to init_early. This fixes an issue where if the GuC init fails we might still try to get the lock in the context cleanup code. Note that it is safe to call the GuC context cleanup code even if the init failed because all contexts are initialized with an invalid GuC ID, which will cause the GuC side of the cleanup to be skipped, so it is easier to just make sure the variables are initialized than to special case the cleanup to handle the case when they're not.

2022-03-01drm/i915/guc: Fix flag query helper function to not modify stateJohn Harrison
A flag query helper was actually writing to the flags word rather than just reading. Fix that. Also update the function's comment as it was out of date. NB: No need for a 'Fixes' tag. The test was only ever used inside a BUG_ON during context registration. Rather than asserting that the condition was true, it was making the condition true. So, in theory, there was no consequence because we should never have hit a BUG_ON anyway. Which means the write should always have been a no-op.

2022-02-28drm/i915: Clarify vma lifetimeThomas Hellström
It's unclear what reference the initial vma kref reference refers to. A vma can have multiple weak references, the object vma list, the vm's bound list and the GT's closed_list, and the initial vma reference can be put from lookups of all these lists. With the current implementation this means that any holder of yet another vma refcount (currently only i915_gem_object_unbind()) needs to be holding two of either *) An object refcount, *) A vm open count *) A vma open count in order for us to not risk leaking a reference by having the initial vma reference being put twice. Address this by re-introducing i915_vma_destroy() which removes all weak references of the vma and *then* puts the initial vma refcount. This makes a strong vma reference hold on to the vma unconditionally. Perhaps a better name would be i915_vma_revoke() or i915_vma_zombify(), since other callers may still hold a refcount, but with the prospect of being able to replace the vma refcount with the object lock in the near future, let's stick with i915_vma_destroy(). Finally this commit fixes a race in that previously i915_vma_release() and now i915_vma_destroy() could destroy a vma without taking the vm->mutex after an advisory check that the vma mm_node was not allocated. This would race with the ungrab_vma() function creating a trace similar to the below one. This was fixed in one of the __i915_vma_put() callsites in commit bc1922e5d349 ("drm/i915: Fix a race between vma / object destruction and unbinding") but although not seemingly triggered by CI, that is not sufficient. This patch is needed to fix that properly.

2022-02-28drm/i915: s/JSP2/ICP2/ PCHVille Syrjälä
This JSP2 PCH actually seems to be some special Apple specific ICP variant rather than a JSP. Make it so. Or at least all the references to it seem to be some Apple ICL machines. Didn't manage to find these PCI IDs in any public chipset docs unfortunately. The only thing we're losing here with this JSP->ICP change is Wa_14011294188, but based on the HSD that isn't actually needed on any ICP based design (including JSP), only TGP based stuff (including MCC) really need it. The documented w/a just never made that distinction because Windows didn't want to differentiate between JSP and MCC (not sure how they handle hpd/ddc/etc. then though...).

2022-02-28drm/tiny: Add MIPI DBI compatible SPI driverNoralf Trønnes
Add a driver that will work with most MIPI DBI compatible SPI panels. This avoids adding a driver for every new MIPI DBI compatible controller that is to be used by Linux. The 'compatible' Device Tree property with a '.bin' suffix will be used to load a firmware file that contains the controller configuration. Example (driver will load sainsmart18.bin): display@0 { compatible = "sainsmart18", "panel-mipi-dbi-spi"; ... }; v5: - kconfig: s/DRM_KMS_CMA_HELPER/DRM_GEM_CMA_HELPER/ (Sam) - kconfig: Add select VIDEOMODE_HELPERS (Sam) - kconfig: Add wiki url in the description (Sam) - Split out and use of_get_drm_panel_display_mode()(Sam) - Only use the first compatible to look for a firmware file since the binding mandates 2 compatibles. - Make having a firmware file mandatory so we can print an error message if it's missing to improve the user experience. It's very unlikely that a controller doesn't need to be initialized and if it doesn't, it's possible to have a firmware file containing only a DCS NOP. v4: - Move driver to drm/tiny where the other drivers of its kind are located. The driver module will not be shared with a future DPI driver after all. v3: - Move properties to DT (Maxime) - The MIPI DPI spec has optional support for DPI where the controller is configured over DBI. Rework the command functions so they can be moved to drm_mipi_dbi and shared with a future panel-mipi-dpi-spi driver v2: - Drop model property and use compatible instead (Rob) - Add wiki entry in MAINTAINERS Acked-by: Maxime Ripard <maxime@cerno.tech> Reviewed-by: Sam Ravnborg <sam@ravnborg.org> Signed-off-by: Noralf Trønnes <noralf@tronnes.org> Signed-off-by: Maxime Ripard <maxime@cerno.tech> Link: https://patchwork.freedesktop.org/patch/msgid/20220227124713.39766-6-noralf@tronnes.org
