| | | | | | | | | | | | | | | | | | | | | | | | In gk20a_fifo_tsg_unbind_channel(), we disable/preempt TSG, unbind one channel from TSG, and then re-enable rest of the channels in TSG But it is possible that TSG has already timed out due to some error and is already disabled If we re-enable all channels in such case, it can cause random issues right after re-enabling faulted channel Hence do not re-enable TSG if it has timedout Since we disable all channels of TSG if one channel encounters fatal error, it is safe to assume that TSG has timed out if one channel has timed out Bug 1958308 Bug 200327095 Change-Id: I958ca6a2b408ff1338f2e551a79c072f1e203eda Signed-off-by: Deepak Nibade <dnibade@nvidia.com> Reviewed-on: https://git-master.nvidia.com/r/1585421 Reviewed-by: mobile promotions <svcmobile_promotions@nvidia.com> Tested-by: mobile promotions <svcmobile_promotions@nvidia.com>
* gpu: nvgpu: add max_css_buffer_size characteristicPeter Daifuku2017-10-25
| | | | | | | | | | | | | | | | | | | | | | | | Add max_css_buffer_size to gpu characteristics. In the virtual case, the size of the cycle stats snapshot buffer is constrained by the size of the mempool shared between the guest OS and the RM server, so tools need to find out what is the maximum size allowed. In the native case, we return 0xffffffff to indicate that the buffer size is unbounded (subject to memory availability), in the virtual case we return the size of the mempool. Also collapse native init_cyclestats functions to a single version, as each chip had identical versions of the code.

* gpu: nvgpu: Fix race in PMU state transitions.Deepak Goyal2017-10-25
| | | | | | | | | | | | | | | | | | | | | PMU response(intr callback for messages) can run faster than the kthread posting commands to PMU. This causes the PMU message callback to skip important pmu state change(which happens just after the PMU command is posted). Solution: State change should be triggered from only inside the intr callback. Other places can only update the pmu_state variable. This change also adds error check to print in case command post fails.

* gpu: nvgpu: Begin reorganizing VM mapping/unmappingAlex Waterman2017-10-24
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Move vm_priv.h to <nvgpu/linux/vm.h> and rename nvgpu_vm_map() to nvgpu_vm_map_linux(). Also remove a redundant unmap function from the unmap path. These changes are the beginning of reworking the nvgpu Linux mapping and unmapping code. The rest of this patch is just the necessary changes to use the new map function naming and the new path to the Linux vm header. Patch Series Goal ----------------- There's two major goals for this patch series. Note that these goals are not achieved in this patch. There will be subsequent patches. 1. Remove all last vestiges of Linux code from common/mm/vm.c 2. Implement map caching in the common/mm/vm.c code To accomplish this firstly the VM mapping code needs to have the struct nvgpu_mapped_buf data struct be completely Linux free. That means implementing an abstraction for this to hold the Linux stuff that mapped buffers carry about (SGT, dma_buf). This is why the vm_priv.h code has been moved: it will need to be included by the <nvgpu/vm.h> header so that the OS specific struct can be pulled into struct nvgpu_mapped_buf. Next renaming the nvgpu_vm_map() to nvgpu_vm_map_linux() is in preparation for adding a new nvgpu_vm_map() that handles the map caching with nvgpu_mapped_buf. The mapping code is fairly straight forward: nvgpu_vm_map does OS generic stuff; each OS then calls this function from an nvgpu_vm_map_<OS>() or the like that does any OS specific adjustments/management. Freeing buffers is much more tricky however. The maps are all reference counted since userspace does not track buffers and expects us to handle this instead. Ugh! Since there's ref-counts the free code will require a callback into the OS specific code since the OS specific code cannot free a buffer directly. THis make's the path for freeing a buffer quite convoluted.

* gpu: nvgpu: Cleanup generic MM code in gk20a/mm_gk20a.cAlex Waterman2017-10-24
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Move much of the remaining generic MM code to a new common location: common/mm/mm.c. Also add a corresponding <nvgpu/mm.h> header. This mostly consists of init and cleanup code to handle the common MM data structures like the VIDMEM code, address spaces for various engines, etc. A few more indepth changes were made as well. 1. alloc_inst_block() has been added to the MM HAL. This used to be defined directly in the gk20a code but it used a register. As a result, if this register hypothetically changes in the future, it would need to become a HAL anyway. This path preempts that and for now just defines all HALs to use the gk20a version. 2. Rename as much as possible: global functions are, for the most part, prepended with nvgpu (there are a few exceptions which I have yet to decide what to do with). Functions that are static are renamed to be as consistent with their functionality as possible since in some cases function effect and function name have diverged.

Reset patch_ctx.data_count before beginning patch write otherwise system might not be in a state to accept all patch writes even if patch buffer has valid entries.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Convert the work_struct used by the vidmem background clearing to a thread to make it more cross platform. The thread waits on a condition variable to determine when work needs to be done. The signal comes from the DMA API when it enqueues a new nvgpu_mem that needs clearing. Add logic for handling suspend: the CE cannot be accessed while the GPU is suspended. As such the background thread must be paused while the GPU is suspended and the CE is not available. Several other changes were also made: o Move the code that enqueues a nvgpu_mem from the DMA API code to a function in the VIDMEM code. o Move nvgpu_vidmem_get_pending_alloc() to the Linux specific code as this function is only used there. It's a trivial function that QNX can easily implement as well. o Remove the was_empty logic from the enqueue. Now just always signal the condition variable when anew nvgpu_mem comes in. o Move CE suspend to after MM suspend.

This removes some usages of dma_buf from the mm_gk20a.c code, too, which helps make mm_gk20a.c less Linux specific. Also delete some header files that are no longer necessary in gk20a/mm_gk20a.c which are Linux specific. The mm_gk20a.c code is now quite close to being Linux free.

* gpu: nvgpu: Move dma_buf usage from mm_gk20a.cAlex Waterman2017-10-18
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Move most of the dma_buf usage present in the mm_gk20a.c code out to Linux specific code and some commom/mm code. There's two primary groups of code: 1. dma_buf priv field code (for holding comptag data) 2. Comptag usage that relies on dma_buf pointers For (1) the dma_buf code was simply moved to common/linux/dmabuf.c since most of this code is clearly Linux specific. The comptag code was a bit more complicated since there is two parts to the comptag code. Firstly there's the code that manages the comptag memory. This is essentially a simple allocator. This was moved to common/mm/comptags.c since it can be shared across all chips. The second set of code is moved to common/linux/comptags.c since it is the interface between dma_bufs and the comptag memory. Two other fixes were done as well: - Add struct gk20a to the comptag allocator init so that the proper nvgpu_vzalloc() function could be used. - Add necessary includes to common/linux/vm_priv.h.

| | | | | | | | | | | | | | | | | | | | | | | | | | | This change contains a generic cleanup of linux dependent parts of the dbg_gpu_gk20a.* files. The following changes have been made 1) Moving methods into ioctl_dbg.* inside common/linux/ 2) The structures dbg_session_gk20a and dbg_session_channel_data have been split into two parts. struct device *dev is removed from struct dbg_session_gk20a and instead packed into struct dbg_session_gk20a_linux alongwith dbg_session_gk20a and is moved into ioctl_dbg. dbg_session_gk20a is now rid of any linux dependencies and remains in dbg_gpu_gk20a. Similarly, struct file is removed from struct dbg_session_channel_data and is now packed into struct dbg_session_channel_data_linux alongwith dbg_session_channel_data and is moved into ioctl_dbg. struct dbg_session_channel_data is now rid of linux dependencies and remains in dbg_gpu_gk20a. 3) A callback function is added in order to release the dbg_session_channel_data.
