2020-01-24drm: Avoid drm_global_mutex for simple inc/dec of dev->open_countChris Wilson1-1/+1
Since drm_global_mutex is a true global mutex across devices, we don't want to acquire it unless absolutely necessary. For maintaining the device local open_count, we can use atomic operations on the counter itself, except when making the transition to/from 0. Here, we tackle the easy portion of delaying acquiring the drm_global_mutex for the final release by using atomic_dec_and_mutex_lock(), leaving the global serialisation across the device opens.

With DSC, bpp can be fractional in multiples of 1/16. Change drm_dp_calc_pbn_mode to reflect this, adding a new parameter bool dsc. When this parameter is true, treat the bpp parameter as having units not of bits per pixel, but 1/16 of a bit per pixel v2: Don't add separate function for this v3: In the equation divide bpp by 16 as it is expected not to leave any remainder v4: Added DSC test parameters for selftest Reviewed-by: Manasi Navare <[email protected]> Reviewed-by: Lyude Paul <[email protected]> Reviewed-by: Harry Wentland <[email protected]> Signed-off-by: David Francis <[email protected]> Signed-off-by: Mikita Lipski <[email protected]> Signed-off-by: Alex Deucher <[email protected]>

git://git.kernel.org/pub/scm/linux/kernel/git/rdma/rdma Pull hmm updates from Jason Gunthorpe: "This is another round of bug fixing and cleanup. This time the focus is on the driver pattern to use mmu notifiers to monitor a VA range. This code is lifted out of many drivers and hmm_mirror directly into the mmu_notifier core and written using the best ideas from all the driver implementations. This removes many bugs from the drivers and has a very pleasing diffstat. More drivers can still be converted, but that is for another cycle. - A shared branch with RDMA reworking the RDMA ODP implementation - New mmu_interval_notifier API. This is focused on the use case of monitoring a VA and simplifies the process for drivers - A common seq-count locking scheme built into the mmu_interval_notifier API usable by drivers that call get_user_pages() or hmm_range_fault() with the VA range - Conversion of mlx5 ODP, hfi1, radeon, nouveau, AMD GPU, and Xen GntDev drivers to the new API.

2019-11-23drm/radeon: use mmu_interval_notifier_insertJason Gunthorpe2-176/+51
The new API is an exact match for the needs of radeon. For some reason radeon tries to remove overlapping ranges from the interval tree, but interval trees (and mmu_interval_notifier_insert()) support overlapping ranges directly. Simply delete all this code. Since this driver is missing a invalidate_range_end callback, but still calls get_user_pages(), it cannot be correct against all races.
