We enable a bunch more compiler warnings than the kernel defaults. However, they've drifted to become a unique set of warnings, and have increasingly fallen behind from the W=1 set. Align with the W=1 warnings from scripts/Makefile.extrawarn for clarity, by copy-pasting them with s/KBUILD_CFLAGS/subdir-ccflags-y/ to make it easier to compare in the future. Some of the -Wextra warnings do need to be disabled, just like in Makefile.extrawarn, but take care to not disable them for W=2 or W=3 builds, depending on the warning. v2: Add back some -Wextra warning disables (Nathan) Cc: Arnd Bergmann <arnd@arndb.de> Cc: Nick Desaulniers <ndesaulniers@google.com> Cc: Nathan Chancellor <nathan@kernel.org> Cc: Masahiro Yamada <masahiroy@kernel.org> Reviewed-by:

The kernel top level Makefile, and recently scripts/Makefile.extrawarn, have included -Wall, and the disables -Wno-format-security and $(call cc-disable-warning,frame-address,) for a very long time. They're redundant in our local subdir-ccflags-y and can be dropped.

Currently, with MFD/pin assignment D, the driver clears the pipe reset bit of lane 1 which is not owned by display. This causes the display to block S0iX. By not clearing this bit for lane 1 and keeping whatever default, S0ix started to work. This is already what the driver does at the end of the phy lane reset sequence (Step#8) Bspec: 65451 Fixes: 619a06db ("drm/i915/mtl: Reset only one lane in case of MFD") Cc: Mika Kahola <mika.kahola@intel.com> Cc: Gustavo Sousa <gustavo.sousa@intel.com> Signed-off-by:

Ville Syrjälä authored
The state checker overwrites the old crtc state with the current hardware state. While that does save a kmalloc() it seems rather dubious as there might still be something that we need in the old crtc state. Stop doing that and just allocate a temporary state for the state checker. Should the extra malloc during the commit phase turn out too annoying we could of course preallocate one for each crtc, but let's proceed with the straightforward approch for now. And while at it let's mark the new crtc state as const to make sure the state checker doesn't mess it up. Signed-off-by:

The 16k max plane stride limit seems to be originally from i965gm, and no explicit limit has been specified since (g4x+). So let's assume the max plane stride itself is a suitable limit also for the more recent FBC hardware. In fact even for i965gm the max X-tiled stride is also 16k so technically we don't need the check there either, but let's keep it there anyway since it's explicitly mentioned in the spec. Gen2/3 have more strict limits checked separately. Reviewed-by:

Use local64_try_cmpxchg instead of local64_cmpxchg (*ptr, old, new) == old in i915_pmu_event_read. x86 CMPXCHG instruction returns success in ZF flag, so this change saves a compare after cmpxchg (and related move instruction in front of cmpxchg). Also, try_cmpxchg implicitly assigns old *ptr value to "old" when cmpxchg fails. There is no need to re-read the value in the loop. No functional change intended.

Current vga arbiter implementation in i915 needs a re-design. The current approach would cause real problems if anyone actually needs to talk another GPU using legacy VGA resources. The main issue is that X becomes a slideshow if it thinks there are multiple GPUs that have VGA decoding enabled as it insists on adjusting the VGA routing pretty much for every little operation involving any of the GPUs. The cleanup will be planned for i915. Meanwhile to focus on Xe upstreaming and have a cleaner separation, the said functionality is being moved to a different file exclusive for i915. Xe driver will re-use rest of the display code from i915. v2: Addressed Jani Nikula's review comments. v3: Dropped a duplicate function (Jani) v4: Updated commit message with reasoning as sugested by Ville.

Atm the MST encoder config computation may use an out-of-date pbn_div value, if the sink is unplugged and a sink is replugged with different link rate/lane count capabilities. The current way of reinitializing pbn_div depends on pbn_div getting cleared via intel_atomic_check() -> drm_dp_mst_atomic_check() -> drm_dp_mst_atomic_check_payload_alloc_limits(), however the clearing won't happen if the sink got unplugged (and hence drm_dp_mst_topology_mgr::mst_state being false). To fix the above, simply update pbn_div unconditionally during config computation, making pbn_div always match the link rate and lane count. Cc: Lyude Paul <lyude@redhat.com> Reviewed-by:

This is to eliminate all cases of "*ERROR* LSPCON mode hasn't settled", followed by link training errors. Intel engineers recommended increasing this timeout and that does resolve the issue. On some CometLake-based device designs the Parade PS175 takes more than 400ms to settle in PCON mode. 100 reboot trials on one device resulted in a median settle time of 440ms and a maximum of 444ms. Even after increasing the timeout to 500ms, 2% of devices still had this error. So this increases the timeout to 800ms. Closes: https://gitlab.freedesktop.org/drm/intel/-/issues/9443Signed-off-by:
