* gpu: nvgpu: separate IOCTL to set preemption modeDeepak Nibade2016-05-09
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Add separate IOCTL NVGPU_IOCTL_CHANNEL_SET_PREEMPTION_MODE to allow setting preemption modes from UMD Define preemption modes in nvgpu.h and use them everywhere Remove mode definitions from mm_gk20a.h Also, we support setting only one preemption mode in a channel But it is possible to have multiple preemption modes (one from graphics and one from compute) set simultaneously Hence, update struct gr_ctx_desc to include two separate preemption modes (graphics_preempt_mode and compute_preempt_mode) API NVGPU_IOCTL_CHANNEL_SET_PREEMPTION_MODE also supports setting two separate preemption modes i.e. one for graphics and one for compute Make necessary changes in code to support two preemption modes Bug 1646259 Change-Id: Ia1dea19e609ba8cc0de2f39ab6c0c4cd6b0a752c Signed-off-by: Deepak Nibade <dnibade@nvidia.com> Reviewed-on: http://git-master/r/1131805 Reviewed-by: Terje Bergstrom <tbergstrom@nvidia.com> Tested-by: Terje Bergstrom <tbergstrom@nvidia.com>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | We currently free sync when we find job list empty If aggressive_sync is set to true, we try to free sync during channel unbind() call But we rarely free sync from channel_unbind() call since freeing it when job list is empty is aggressive enough Hence remove sync free code from channel_unbind() Implement refcounting for sync: - get a refcount while submitting a job (and allocate sync if it is not allocated already) - put a refcount while freeing the job - if refcount==0 and if aggressive_sync_destroy is set, free the sync - if aggressive_sync_destroy is not set, we will free the sync during channel close time Bug 200187553 Change-Id: I74e24adb15dc26a375ebca1fdd017b3ad6d57b61 Signed-off-by: Deepak Nibade <dnibade@nvidia.com> Reviewed-on: http://git-master/r/1120410 Reviewed-by: Terje Bergstrom <tbergstrom@nvidia.com> Tested-by: Terje Bergstrom <tbergstrom@nvidia.com>

* gpu: nvgpu: support binding multiple channels to a debug sessionDeepak Nibade2016-04-19
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | We currently bind only one channel to a debug session But some use cases might need multiple channels bound to same debug session Add this support by adding a list of channels to debug session. List structure is implemented as struct dbg_session_channel_data List node dbg_s_list_node is currently defined in struct dbg_session_gk20a. But this is inefficient when we need to add debug session to multiple channels Hence add new reference structure dbg_session_data to store dbg_session pointer and list entry For each NVGPU_DBG_GPU_IOCTL_BIND_CHANNEL call, create two reference structure dbg_session_channel_data for channel and dbg_session_data for debug session and bind them together Define API nvgpu_dbg_gpu_get_session_channel() which will get first channel in the list of debug session Use this API wherever we refer to channel bound to debug session Remove dbg_sessions define in struct gk20a since it is not being used anywhere Add new API NVGPU_DBG_GPU_IOCTL_UNBIND_CHANNEL to support unbinding of channel from debug sesssion Bug 200156699 Change-Id: I3bfa6f9cd5b90e7254a75c7e64ac893739776b7f Signed-off-by: Deepak Nibade <dnibade@nvidia.com> Reviewed-on: http://git-master/r/1120331 GVS: Gerrit_Virtual_Submit Reviewed-by: Terje Bergstrom <tbergstrom@nvidia.com>
