| | | | | | | | | | | Make pagepool size query into a function instead of storing the value during boot time in a structure. This simplifies the structure and users of pagepool size do not need to worry about whether it has already been set.

* gpu: nvgpu: fix gm20b floorsweep APIDeepak Nibade2015-03-18
| | | | | | | | | | | | | | | | | | | | | | | | Rewrite gr_gm20b_ctx_state_floorsweep() to include necessary register writes for gm20b tpc floorsweeping. This includes : - update the loop to write gr_gpc0_tpc0_sm_cfg_r() and gr_gpc0_gpm_pd_sm_id_r() - for gr_pd_num_tpc_per_gpc_r(i), we just need to write register with i = 0 and the value being written is tpc count in that gpc - gr_fe_tpc_fs_r() needs to have logical list of TPCs after floorsweeping. Get this value from pes_tpc_mask. - gr_cwd_gpc_tpc_id_tpc0_f() and gr_cwd_sm_id_tpc0_f() also refer to logical ids and hence no need to check tpc_fs_mask to configure these registers Bug 1513685 Change-Id: I82dc36a223fbd21e814e58e4d67738d7c63f04a7 Signed-off-by: Deepak Nibade <dnibade@nvidia.com> Reviewed-on: http://git-master/r/601117 Reviewed-by: Sachin Nikam <snikam@nvidia.com>
* gpu: nvgpu: support config of TPC FUSE dynamicallyDeepak Nibade2015-03-18
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | Follow steps below to config active TPC number: echo 1 > /sys/devices/platform/host1x/gpu.0/force_idle echo 0x1/0x2/0x3 > /sys/devices/platform/host1x/gpu.0/tpc_fs_mask echo 0 > /sys/devices/platform/host1x/gpu.0/force_idle where, 0x1 : disable TPC1 0x2 : disable TPC0 0x3 : both TPCs active Also, add API set_gpc_tpc_mask to update the TPCs and call this API after update to sysfs "tpc_fs_mask" Once fuses are updated for new TPC settings, we need to reconfigure GR and golden_image. Hence disable gr->sw_ready and golden_image_initialized flags. Also, initialize gr->tpc_count = 0 each time in gr_gk20a_init_gr_config(), otherwise it goes on adding tpc count Bug 1513685 Change-Id: Ib50bafef08664262f8426ac0d6cbad74b32c5909 Signed-off-by: Kevin Huang <kevinh@nvidia.com> Signed-off-by: Deepak Nibade <dnibade@nvidia.com> Reviewed-on: http://git-master/r/552606 Reviewed-by: Sachin Nikam <snikam@nvidia.com>
