2022-01-14drm/ttm: fix compilation on ARCH=umJohannes Berg1-1/+3
Even if it's probably not really useful, it can get selected by e.g. randconfig builds, and then failing to compile is an annoyance. Unfortunately, it's hard to fix in Kconfig, since DRM_TTM is selected by many things that don't really depend on any specific architecture, and just depend on PCI (which is indeed now available in ARCH=um via simulation/emulation). Fix this in the code instead by just ifdef'ing the relevant two lines that depend on "real X86".

2022-01-13drm/panfrost: Merge some feature listsAlyssa Rosenzweig1-33/+7
Now that we only list features of interest to kernel space, lots of GPUs have the same feature bits. To cut down on the repetition in the file, merge feature lists that are identical between similar GPUs. Note that this leaves some unmerged identical Bifrost feature lists, as there are more features affecting Bifrost kernel space that we do not yet handle.

2022-01-13drm/panfrost: Remove features meant for userspaceAlyssa Rosenzweig1-172/+0
Early versions of the legacy kernel driver included comprehensive feature lists for every GPU, even though most of the enumerated features only matter to userspace. For example, HW_FEATURE_INTERPIPE_REG_ALIASING was a feature bit indicating that a GPU had "interpipe register aliasing": arithmetic, load/store, and texture instruction all use common general-purpose registers. GPUs without this feature bit have dedicated load/store and texture "registers". Whether a GPU has this feature or not is irrelevant to the kernel; it only matters in the userspace compiler's register allocator. It's silly to enumerate it in kernel space, and the information is understandably unused. To underscore the point, this feature only makes sense in the context of the Midgard instruction set. Bifrost never had dedicated load/store or texture registers, so the feature bit was vacuously set for all Bifrost hardware, even though this conveys no useful information. To clean up the feature list, delete feature bits which could not possibly matter to the kernel, leaving only those which do affect the register-level operation of the chip.
