drm/nouveau: fix relocations applying logic and a double-free 2020-12-02T07:51:59+00:00 Matti Hamalainen ccr@tnsp.org 2020-11-20T15:23:38+00:00 32083f0da6869aa6ef11dbda93394aa5f398d594 [ Upstream commit 2be65641642ef423f82162c3a5f28c754d1637d2 ] Commit 03e0d26fcf79 ("drm/nouveau: slowpath for pushbuf ioctl") included a logic-bug which results in the relocations not actually getting applied at all as the call to nouveau_gem_pushbuf_reloc_apply() is never reached. This causes a regression with graphical corruption, triggered when relocations need to be done (for example after a suspend/resume cycle.) Fix by setting *apply_relocs value only if there were more than 0 relocations. Additionally, the never reached code had a leftover u_free() call, which, after fixing the logic, now got called and resulted in a double-free. Fix by removing one u_free(), moving the other and adding check for errors.

which, after fixing the logic, now got called and resulted in a

EDID can declare the maximum supported bpc up to 16, and apparently there are displays that do so. Currently we assume 12 bpc is tha max. Fix the assumption and toss in a MISSING_CASE() for any other value we don't expect to see. This fixes modesets with a display with EDID max bpc > 12. Previously any modeset would just silently fail on platforms that didn't otherwise limit this via the max_bpc property. In particular we don't add the max_bpc property to HDMI ports on gmch platforms, and thus we would see the raw max_bpc coming from the EDID. I suppose we could already adjust this to also allow 16bpc, but seeing as no current platform supports that there is little point.
