| | | | | | | | | | | | | | | | | In gk20a_fifo_handle_sched_error(), we currently cancel the timeout on all the channels But this could cause us to miss one of stuck channel hence, instead of cancelling, restart the timeout of channel on which it is already active Bug 200133289 Change-Id: I40e7e0e5394911fc110ab6fde39592b885dfaf7d Signed-off-by: Deepak Nibade <dnibade@nvidia.com> Reviewed-on: http://git-master/r/816133 Reviewed-by: Ishan Mittal <imittal@nvidia.com> Tested-by: Ishan Mittal <imittal@nvidia.com>

| | | | | | | | | | | | | | | | | | | | | | In gk20a_channel_timeout_stop(), we take the channel's timeout lock and then cancel the timeout worker thread Timeout worker thread also tries to acquire same timeout lock.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Currently, if can_railgate = false, then we have below sequence to allocate secure_page - unrailgate GPU (forever) - reset_assert() - allocate secure_page - reset_deassert() But if we allocate secure page even before unrailgating GPU for first time, then we can avoid reset_assert()/deassert() calls since GPU should already be in reset/railgated at boot time hence, rework this sequence as below - init required mutex, set platform->reset_control - allocate secure page (GPU should already be in reset at this point) - gk20a_pm_init() which unrailgates GPU in case of can_railgate = false Bug 200137963 Bug 1678611 Change-Id: I79d0543bb5cf1eaf1009e1e6ac142532d84514a5 Signed-off-by: Deepak Nibade <dnibade@nvidia.com> Reviewed-on: http://git-master/r/797153 (cherry picked from commit 368004501943d38c003747f6bec0384fed57ee65) Reviewed-on: http://git-master/r/816005 GVS: Gerrit_Virtual_Submit Reviewed-by: Terje Bergstrom <tbergstrom@nvidia.com>

| | | | | | | | | | | | | | | | Add support for CDE scatter buffers. When the bus addresses for surfaces are not contiguous as seen by the GPU (e.g., when SMMU is bypassed), CDE swizzling needs additional per-page information.
