2019-09-13drm/amd/display: remove hw access from dc_destroyJun Lei2-4/+0
[why] dc_destroy should only clean up SW, this is because GPUs may be removed before driver unload, leading to HW to be unavailable. [how] remove GPIO close as part of GPIO destroy, this is unnecessary because GPIO is not shared, and GPIOs are generally closed after being opened Add tracking to HW access during destructor to make future issues easier to pinpoint, and block access to prevent hangs.

2018-11-30drm/amd/display: fix sporadic multiple aux transaction failureYogesh Mohan Marimuthu2-51/+21
[why] When there are multiple aux transaction in parallel, it is sometime sporadically the aux transaction starts to continuously fail. The aux transaction was failing because the busy bit for the given gpio pin was always set. The busy bit was alway set because the programming sequence to read, modify and write busy bit was not atomic. Due to which when multiple threads are trying to modify the busy bits for their gpio pins in the same integer variable sometimes the busy bits integer variable is written with old data causing failure. [how] Instead of using individual bits to track gpio pins and grouping them to integers, one byte will be allcoated for each gpio pin. Now whenever a gpio pin needs to be set to mark being used, only writing a value of one to that byte is sufficient, other bytes are not impacted. Also no need to have atomicity with bytes unlike with bits.

2018-06-12treewide: kzalloc() -> kcalloc()Kees Cook1-1/+2
The kzalloc() function has a 2-factor argument form, kcalloc(). This patch replaces cases of: kzalloc(a * b, gfp) with: kcalloc(a * b, gfp) as well as handling cases of: kzalloc(a * b * c, gfp) with: kzalloc(array3_size(a, b, c), gfp) as it's slightly less ugly than: kzalloc_array(array_size(a, b), c, gfp) This does, however, attempt to ignore constant size factors like: kzalloc(4 * 1024, gfp) though any constants defined via macros get caught up in the conversion. Any factors with a sizeof() of "unsigned char", "char", and "u8" were dropped, since they're redundant. The Coccinelle script used for this was: // Fix redundant parens around sizeof(). @@ type TYPE; expression THING, E; @@ ( kzalloc( - (sizeof(TYPE)) * E + sizeof(TYPE) * E , ...) | kzalloc( - (sizeof(THING)) * E + sizeof(THING) * E , ...) ) // Drop single-byte sizes and redundant parens. @@ expression COUNT;
