2021-02-18drm/amd/display: Fix potential integer overflowGustavo A. R. Silva1-1/+1
Fix potential integer overflow by casting actual_calculated_clock_100hz to u64, in order to give the compiler complete information about the proper arithmetic to use. Notice that such variable is used in a context that expects an expression of type u64 (64 bits, unsigned) and the following expression is currently being evaluated using 32-bit arithmetic: actual_calculated_clock_100hz * post_divider Fixes: 7a03fdf628af ("drm/amd/display: fix 64bit division issue on 32bit OS") Addresses-Coverity-ID: 1501691 ("Unintentional integer overflow") Signed-off-by: Gustavo A.

2021-02-17drm/i915: Disallow plane x+w>stride on ilk+ with X-tilingVille Syrjälä3-6/+39
ilk+ planes get notably unhappy when the plane x+w exceeds the stride. This wasn't a problem previously because we always aligned SURF to the closest tile boundary so the x offset never got particularly large. But now with async flips we have to align to 256KiB instead and thus this becomes a real issue. On ilk/snb/ivb it looks like the accesses just wrap early to the next tile row when scanout goes past the SURF+n*stride boundary, hsw/bdw suffer more heavily and start to underrun constantly. i965/g4x appear to be immune. vlv/chv I've not yet checked. Let's borrow another trick from the skl+ code and search backwards for a better SURF offset in the hopes of getting the x offset below the limit. IIRC when I ran into a similar issue on skl years ago it was causing the hardware to fall over pretty hard as well. And let's be consistent and include i965/g4x in the check as well, just in case I just got super lucky somehow when I wasn't able to reproduce the issue. Not that it really matters since we still use 4k SURF alignment for i965/g4x anyway.

2021-02-16kcmp: Support selection of SYS_kcmp without CHECKPOINT_RESTOREChris Wilson1-0/+3
Userspace has discovered the functionality offered by SYS_kcmp and has started to depend upon it. In particular, Mesa uses SYS_kcmp for os_same_file_description() in order to identify when two fd (e.g. device or dmabuf) point to the same struct file. Since they depend on it for core functionality, lift SYS_kcmp out of the non-default CONFIG_CHECKPOINT_RESTORE into the selectable syscall category. Rasmus Villemoes also pointed out that systemd uses SYS_kcmp to deduplicate the per-service file descriptor store. Note that some distributions such as Ubuntu are already enabling CHECKPOINT_RESTORE in their configs and so, by extension, SYS_kcmp.
