2022-06-14drm/ttm: fix bulk move handling v2Christian König1-4/+4
The resource must be on the LRU before ttm_lru_bulk_move_add() is called and we need to check if the BO is pinned or not before adding it. Additional to that we missed taking the LRU spinlock in ttm_bo_unpin().

LoongArch maintains cache coherency in hardware, but its WUC attribute (Weak-ordered UnCached, which is similar to WC) is out of the scope of cache coherency machanism.

2022-05-28drm: fix EDID struct for old ARM OABI formatLinus Torvalds1-3/+3
When building the kernel for arm with the "-mabi=apcs-gnu" option, gcc will force alignment of all structures and unions to a word boundary (see also STRUCTURE_SIZE_BOUNDARY and the "-mstructure-size-boundary=XX" option if you're a gcc person), even when the members of said structures do not want or need said alignment. This completely messes up the structure alignment of 'struct edid' on those targets, because even though all the embedded structures are marked with "__attribute__((packed))", the unions that contain them are not. This was exposed by commit f1e4c916f97f ("drm/edid: add EDID block count and size helpers"), but the bug is pre-existing. That commit just made the structure layout problem cause a build failure due to the addition of the BUILD_BUG_ON(sizeof(*edid) != EDID_LENGTH); sanity check in drivers/gpu/drm/drm_edid.c:edid_block_data(). This legacy union alignment should probably not be used in the first place, but we can fix the layout by adding the packed attribute to the union entries even when each member is already packed and it shouldn't matter in a sane build environment. You can see this issue with a trivial test program: union { struct { char c[5]; }; struct { char d; unsigned e; } __attribute__((packed)); } a = { "1234" }; where building this with a normal "gcc -S" will result in the expected 5-byte size of said union: .type a, @object .size a, 5 but with an ARM compiler and the old ABI: arm-linux-gnu-gcc -mabi=apcs-gnu -mfloat-abi=soft -S t.c you get .type a, %object .size a, 8 instead, because even though each member of the union is packed, the union itself still gets aligned. This was reported by Sudip for the spear3xx_defconfig target.

2022-05-02drm: handle kernel fences in drm_gem_plane_helper_prepare_fb v2Christian König2-5/+1
drm_gem_plane_helper_prepare_fb() was using drm_atomic_set_fence_for_plane() which ignores all implicit fences when an explicit fence is already set. That's rather unfortunate when the fb still has a kernel fence we need to wait for to avoid presenting garbage on the screen. So instead update the fence in the plane state directly. While at it also take care of all potential GEM objects and not just the first one. Also remove the now unused drm_atomic_set_fence_for_plane() function, new drivers should probably use the atomic helpers directly. v2: improve kerneldoc, use local variable and num_planes, WARN_ON_ONCE on missing planes.

2022-03-29drm/i915: Add a DP1.2 compatible way to read LTTPR capabilitiesImre Deak1-0/+2
At least some DELL monitors (P2715Q) with DPCD_REV 1.2 return corrupted DPCD register values when reading from the 0xF0000- LTTPR range with an AUX transaction block size bigger than 1. The DP standard requires 0 to be returned - as for any other reserved/invalid addresses - but these monitors return the DPCD_REV register value repeated in each byte of the read buffer. This will in turn corrupt the values returned by the LTTPRs between the source and the monitor: LTTPRs must adjust the values they read from the downstream DPRX, for instance right-shift/init the downstream DP_PHY_REPEATER_CNT value. Since the value returned by the monitor's DPRX is non-zero the adjusted values will be corrupt. Reading the LTTPR registers one-by-one instead of reading all of them with a single AUX transfer works around the issue. According to the DP standard's 0xF0000 register description: "LTTPR-related registers at DPCD Addresses F0000h through F02FFh are valid only for DPCD r1.4 (or higher)." While it's unclear if DPCD r1.4 refers to the DPCD_REV or to the LT_TUNABLE_PHY_REPEATER_FIELD_DATA_STRUCTURE_REV register (tickets filed at the VESA site to clarify this haven't been addressed), one possibility is that it's a restriction due to non-compliant monitors described above. Disabling the non-transparent LTTPR mode for all such monitors is not a viable solution: the transparent LTTPR mode has its own issue causing link training failures and this would affect a lot of monitors in use with DPCD_REV < 1.4. Instead this patch works around the problem by reading the LTTPR common and PHY cap registers one-by-one for any monitor with a DPCD_REV < 1.4. The standard requires the DPCD capabilities to be read after the LTTPR common capabilities are read, so re-read the DPCD capabilities after the LTTPR common and PHY caps were read out. v2: - Use for instead of a while loop. (Ville) - Add to code comment the monitor model with the problem.
