* gpu: nvgpu: Direct GMMU PTE kind controlSami Kiminki2017-09-15
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Allow userspace to control directly the PTE kind for the mappings by supplying NVGPU_AS_MAP_BUFFER_FLAGS_DIRECT_KIND_CTRL for MAP_BUFFER_EX. In particular, in this mode, the userspace will tell the kernel whether the kind is compressible, and if so, what is the incompressible fallback kind. By supplying only the compressible kind, the userspace can require that the map kind will not be demoted to the incompressible fallback kind in case of comptag allocation failure. Add also a GPU characteristics flag NVGPU_GPU_FLAGS_SUPPORT_MAP_DIRECT_KIND_CTRL to signal whether direct kind control is supported. Fix indentation of nvgpu_as_map_buffer_ex_args header comment.

* gpu: nvgpu: hold ch ref when getting ch from fdKonsta Holtta2017-09-11
| | | | | | | | | | | | | | | | | Fix a race condition in gk20a_get_channel_from_file() that returns a channel pointer from an fd: take a reference to the channel before putting the file ref back. Now the caller is responsible of releasing the channel reference eventually. Also document why dbg_session_channel_data has to hold a ref to the channel file instead of just the channel: that might deadlock if the fds were closed in "wrong" order.

* gpu: nvgpu: Add and use VM init/deinit APIsAlex Waterman2017-05-26
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Remove the VM init/de-init from the HAL and instead use a single set of routines that init/de-init VMs. This prevents code divergence between vGPUs and regular GPUs. This patch also clears up the naming of the routines a little bit. Since some VMs are used inplace and others are dynamically allocated the APIs for freeing them were confusing. Also some free calls also clean up an instance block (this is API abuse - but this is how it currently exists). The new API looks like this: void __nvgpu_vm_remove(struct vm_gk20a *vm); void nvgpu_vm_remove(struct vm_gk20a *vm); void nvgpu_vm_remove_inst(struct vm_gk20a *vm, struct nvgpu_mem *inst_block); void nvgpu_vm_remove_vgpu(struct vm_gk20a *vm); int nvgpu_init_vm(struct mm_gk20a *mm, struct vm_gk20a *vm, u32 big_page_size, u64 low_hole, u64 kernel_reserved, u64 aperture_size, bool big_pages, bool userspace_managed, char *name); void nvgpu_deinit_vm(struct vm_gk20a *vm); JIRA NVGPU-12 JIRA NVGPU-30 Change-Id: Ia4016384c54746bfbcaa4bdd0d29d03d5d7f7f1b Signed-off-by: Alex Waterman <alexw@nvidia.com> Reviewed-on: http://git-master/r/1477747 Reviewed-by: Automatic_Commit_Validation_User GVS: Gerrit_Virtual_Submit Reviewed-by: Terje Bergstrom <tbergstrom@nvidia.com>

* gpu: nvgpu: Split VM implementation outAlex Waterman2017-05-19
| | | | | | | | | | | | | | | | | | | | This patch begins splitting out the VM implementation from mm_gk20a.c and moves it to common/linux/vm.c and common/mm/vm.c. This split is necessary because the VM code has two portions: first, an interface for the OS specific code to use (i.e userspace mappings), and second, a set of APIs for the driver to use (init, cleanup, etc) which are not OS specific. This is only the beginning of the split - there's still a lot of things that need to be carefully moved around.

* gpu: nvgpu: Split VM interface outAlex Waterman2017-05-19
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch begins the major rework of the GPU's virtual memory manager (VMM). The VMM is the piece of code that handles the userspace interface to buffers and their mappings into the GMMU. The core data structure is the VM - for now still known as 'struct vm_gk20a'. Each one of these structs represents one addres space to which channels or TSGs may bind themselves to. The VMM splits the interface up into two broad categories. First there's the common, OS independent interfaces; and second there's the OS specific interfaces. OS independent -------------- This is the code that manages the lifetime of VMs, the buffers inside VMs (search, batch mapping) creation, destruction, etc. OS Specific ----------- This handles mapping of buffers represented as they are represented by the OS (dma_buf's for example on Linux). This patch is by no means complete. There's still Linux specific functions scattered in ostensibly OS independent code. This is the first step. A patch that rewrites everything in one go would simply be too big to effectively review. Instead the goal of this change is to simply separate out the basic OS specific and OS agnostic interfaces into their own header files. The next series of patches will start to pull the relevant implementations into OS specific C files and common C files.

| | | | | | | | | | | | | | | | | | | | | | Change nvgpu_kalloc() to nvgpu_big_[mz]alloc(). This is necessary since the natural free function name for this is nvgpu_kfree() but that conflicts with nvgpu_k[mz]alloc() (implemented in a subsequent patch). This API exists becasue not all allocation sizes can be determined at compile time and in some cases sizes may vary across the system page size. Thus always using kmalloc() could lead to OOM errors due to fragmentation. But always using vmalloc() is wastful of memory for small allocations. This API tries to alleviate those problems.
