* gpu: nvgpu: initialze bundle64 stateDeepak Nibade2018-06-14
| | | | | | | | | | | | | | | | | | | | | | | | | | | We receive bundle with address and 64 bit values from ucode on some platforms This patch adds the support to handle 64 bit values Add struct av64_gk20a to store an address and corresponding 64 bit value Add struct av64_list_gk20a to store count and list of av64_gk20a Add API alloc_av64_list_gk20a() to allocate the list that supports 64bit values In gr_gk20a_init_ctx_vars_fw(), if we see NETLIST_REGIONID_SW_BUNDLE64_INIT, load the bundle64 state into above local structures Add new HAL gops.gr.init_sw_bundle64() and call it from gk20a_init_sw_bundle() if defined Also load the bundle for simulation cases in gr_gk20a_init_ctx_vars_sim() Jira NVGPUT-96 Change-Id: I1ab7fb37ff91c5fbd968c93d714725b01fd4f59b Signed-off-by: Deepak Nibade <dnibade@nvidia.com> Reviewed-on: https://git-master.nvidia.com/r/1736450 Reviewed-by: mobile promotions <svcmobile_promotions@nvidia.com> Tested-by: mobile promotions <svcmobile_promotions@nvidia.com>

* gpu: nvgpu: fix crash due to accessing incorrect TSG pointerDeepak Nibade2018-06-14
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | In gk20a_gr_isr(), we handle various errors including GPC/TPC errors. And then if BPT errors are pending we call gk20a_gr_post_bpt_events() at the end and pass channel pointer to it gk20a_gr_post_bpt_events() extracts TSG pointer based on ch->tsgid But in some race conditions it is possible that we clear the error and trigger recovery and as a result channel is unbounded from TSG and closed by user space before calling gk20a_gr_post_bpt_events() And in that case the code above results in getting incorrect TSG pointer and hence crashes as below Unable to handle kernel paging request at virtual address ffffff8012000c08 ...

* gpu: nvgpu: handle clk arb event posting in OS specific codeSourab Gupta2018-05-18
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | The mechanism of posting events to userspace is OS specific. In linux this works through poll fd, wherein we can make use of nvgpu_cond variables to poll and trigger the corresponding wait_queue. The post event functionality on QNX doesn't work on poll though. It uses iofunc_notify_trigger to post the events to the calling process. As such QNX can't work with nvgpu_cond's. To overcome this issue, it is proposed to create OS specific interface function for posting clk arb events. Linux can call nvgpu_cond based implementation, which makes sense since these are already initialized and poll'ed in Linux specific code only. QNX can implement this interface to call iofunc_notify_* functions, as per its need.
