2021-09-23drm/i915/display: Match PSR2 selective fetch sequences with specificationJosé Roberto de Souza
We were not completely following the selective fetch programming sequence, here some things we were doing wrong: - not programming plane selective fetch a PSR2_MAN_TRK_CTL registers when doing a modeset - programming PSR2_MAN_TRK_CTL out of vblank With this changes the last remainig underrun found in Alderlake-P is fixed.

2021-09-23drm/i915/guc, docs: Fix pdfdocs build error by removing nested gridAkira Yokosawa
Nested grids in grid-table cells are not specified as proper ReST constructs. Commit 572f2a5cd974 ("drm/i915/guc: Update firmware to v62.0.0") added a couple of kerneldoc tables of the form: +---+-------+------------------------------------------------------+ | 1 | 31:0 | +------------------------------------------------+ | +---+-------+ | | | |...| | | Embedded `HXG Message`_ | | +---+-------+ | | | | n | 31:0 | +------------------------------------------------+ | +---+-------+------------------------------------------------------+ For "make htmldocs", they happen to work as one might expect, but they are incompatible with "make latexdocs" and "make pdfdocs", and cause the generated gpu.tex file to become incomplete and unbuildable by xelatex.

2021-09-23drm/i915/adlp: Add support for remapping CCS FBsImre Deak
Add support for remapping CCS FBs on ADL-P to remove the restriction of the power-of-two sized stride and the 2MB surface offset alignment for these FBs. We can only remap the tiles on the main surface, not the tiles on the CCS surface, so userspace has to generate the CCS surface aligning to the POT size padded main surface stride (by programming the AUX pagetable accordingly). For the required AUX pagetable setup, this requires that either the main surface stride is 8 tiles or that the stride is 16 tiles aligned (= 64 kbytes, the area mapped by one AUX PTE). v2: - Init intel_remapped_info::plane_alignment only for remapped views and do this from intel_fb_view_init().

2021-09-23drm/i915/adlp: Require always a power-of-two sized CCS surface strideImre Deak
At the moment CCS FB strides must be power-of-two sized, but a follow-up change will add support remapping these FBs, allowing the FB passed in by userspace to have a non-POT sized stride. For these remapped FBs we can only remap the main surface, not the CCS surface. This means that userspace has to always generate the CCS surface aligning to the POT stride padded main surface (by setting up the CCS AUX pagetables accordingly). Adjust the CCS surface stride check to enforce this. No functional change. v2: - Fix the gen12_ccs_aux_stride() is not static sparse warning.

2021-09-23drm/i915: Use tile block based dimensions for CCS origin x, y checkImre Deak
The tile size for all surface types is 4 kbyte (or 2 kbyte on old platforms), with the exception of the TGL/ADL CCS surface where the tile size is 64 bytes. To be able to remap CCS FBs the CCS surface tile needs to be defined as 4 kbyte as well (the granularity of GTT pages in a remapped view). The only place using the dimension of the 64 byte CCS area is the initial check for the main vs. CCS plane origin coordinate match. To prepare for adding support for remapping CCS FBs let's call the 64 byte CCS area a 'tile block' and add a helper to retrieve the dimensions for it. No functional change.

2021-09-21drm/rockchip: add DRM_BRIDGE_ATTACH_NO_CONNECTOR flag to drm_bridge_attachAlex Bee
Commit a25b988ff83f ("drm/bridge: Extend bridge API to disable connector creation") added DRM_BRIDGE_ATTACH_NO_CONNECTOR bridge flag and all bridges handle this flag in some way since then. Newly added bridge drivers must no longer contain the connector creation and will fail probing if this flag isn't set. In order to be able to connect to those newly added bridges as well, make use of drm_bridge_connector API and have the connector initialized by the display controller.

2021-09-21drm/rockchip: handle non-platform devices in rockchip_drm_endpoint_is_subdriverAlex Bee
As discussed at [1] rockchip_drm_endpoint_is_subdriver will currently always return -ENODEV for non-platform-devices (e.g. external i2c bridges), what makes them never being considered in rockchip_rgb_init. As suggested at [1] this additionally adds a of_device_is_available for the node found, which will work for both platform and non-platform devices. Also we can return early for non-platform-devices if they are enabled, as rockchip_sub_drivers contains exclusively platform-devices.

2021-09-20drm/i915/xehp: Check new fuse bits for SFC availabilityMatt Roper
Xe_HP adds some new bits to the FUSE1 register to let us know whether a given SFC unit is present. We should take this into account while initializing SFC availability to our VCS and VECS engines. While we're at it, update the FUSE1 register definition to use REG_GENMASK / REG_FIELD_GET notation. Note that, the bspec confusingly names the fuse bits "disable" despite the register reflecting the *enable* status of the SFC units. The original architecture documents which the bspec is based on do properly name this field "SFC_ENABLE."

2021-09-20drm/i915/guc: put all guc objects in lmem when availableDaniele Ceraolo Spurio
The firmware binary has to be loaded from lmem and the recommendation is to put all other objects in there as well. Note that we don't fall back to system memory if the allocation in lmem fails because all objects are allocated during driver load and if we have issues with lmem at that point something is seriously wrong with the system, so no point in trying to handle it.
