2020-07-16treewide: Remove uninitialized_var() usageKees Cook1-1/+1
Using uninitialized_var() is dangerous as it papers over real bugs[1] (or can in the future), and suppresses unrelated compiler warnings (e.g. "unused variable"). If the compiler thinks it is uninitialized, either simply initialize the variable or make compiler changes. In preparation for removing[2] the[3] macro[4], remove all remaining needless uses with the following script: git grep '\buninitialized_var\b' | cut -d: -f1 | sort -u | \ xargs perl -pi -e \ 's/\buninitialized_var\(([^\)]+)\)/\1/g; s:\s*/\* (GCC be quiet|to make compiler happy) \*/$::g;' drivers/video/fbdev/riva/riva_hw.c was manually tweaked to avoid pathological white-space. No outstanding warnings were found building allmodconfig with GCC 9.3.0 for x86_64, i386, arm64, arm, powerpc, powerpc64le, s390x, mips, sparc64, alpha, and m68k.

2020-07-09drm/edid: Iterate through all DispID ext blocksVille Syrjälä1-46/+38
Apparently there are EDIDs in the wild with multiple DispID extension blocks. Iterate through them all. In one particular case the tile information is specicied in the second DispID ext block, and since the current parser only looks at the first DispID ext block we don't notice that we're dealing with a tiled display. While at it change a few functions to return void since we have no use for the errno.

2020-06-30drm: Introduce epoch counter to drm_connectorStanislav Lisovskiy1-3/+5
This counter will be used by drm_helper_probe_detect caller to determine if anything had changed(including edid, connection status and etc). Hardware specific driver detect hooks are responsible for updating this counter when some change is detected to notify the drm part, which can trigger for example hotplug event. Also now call drm_connector_update_edid_property right after we get edid always to make sure there is a unified way to handle edid change, without having to change tons of source code as currently drm_connector_update_edid_property is called only in certain cases like reprobing and not right after edid is actually updated. v2: Added documentation for the new counter.

2020-03-18drm/edid: Fix DispID tile parsing for override EDIDVille Syrjälä1-23/+10
Currently the DispID tile block gets parsed in drm_get_edid(), which is an odd place for it considering we parse nothing else there. Also this doesn't work for override EDIDs since drm_connector_update_edid_property() refuses to do its job twice in such cases. Thus we never update the tile property with results of the DispID tile block parsing during drm_get_edid(). To fix this let's just move the tile block parsing to happen during drm_connector_update_edid_property(), which is where we parse a bunch of other stuff as well (and where we update both the EDID and tile properties).

Currently the code assumes that the entire EDID extesion block can be taken up by the DispID blocks. That is not true. There is at least always the DispID checksum, and potentially fill bytes if the extension block uses the interior fill scheme to pad out to fill EDID block size.

Variables declared in a switch statement before any case statements cannot be automatically initialized with compiler instrumentation (as they are not part of any execution flow). With GCC's proposed automatic stack variable initialization feature, this triggers a warning (and they don't get initialized). Clang's automatic stack variable initialization (via CONFIG_INIT_STACK_ALL=y) doesn't throw a warning, but it also doesn't initialize such variables[1]. Note that these warnings (or silent skipping) happen before the dead-store elimination optimization phase, so even when the automatic initializations are later elided in favor of direct initializations, the warnings remain.

Currently we assume any 18 byte descriptor to be a display descritor if only the tag byte matches the expected value. But for detailed timing descriptors that same byte is just the lower 8 bits of hblank, and as such can match any display descriptor tag. To properly validate that the 18 byte descriptor is in fact a display descriptor we must also examine bytes 0-2 (just byte 1 should actually suffice but the spec does say that bytes 0 and 2 must also always be zero for display descriptors so we check those too).
