| | | | | | | | | | | | | | | | | | Move the platform_gk20a.h include out of the ifdef CONFIG_DEBUG_FS in the CDE code since dev_from_gk20a() is used regardless of whether debugfs is enabled. Also modify some of the CE ops to take a struct gk20a instead of a struct device. This avoids any requirement for including linux/device.h or platform_gk20a.h.

* gpu: nvgpu: remove duplicate \n from log messagesStephen Warren2017-05-26
| | | | | | | | | | | | | | | nvgpu_log/info/warn/err() internally add a \n to the end of the message. Hence, callers should not include a \n at the end of the message. Doing so results in duplicate \n being printed, which ends up creating empty log messages. Remove the duplicate \n from all err/warn messages.

* gpu: nvgpu: Split stalling interrupt handlingTerje Bergstrom2017-05-26
| | | | | | | | | | | | | | | | | | | | | | Split handling of stalling interrupt to Linux specific chip agnostic and OS independent chip specific parts. Linux specific chip independent part contains handler for ISR and passing the control to a bottom half. It uses the new MC HALs intr_stall (query interrupt status), intr_pause (pause interrupts) and intr_resume (resume interrupts). MC HAL isr_stall now returns void and gets called in thread context and thus remove isr_thread_stall and replace the implementation with isr_stall.

* 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_area management into vm codeAlex Waterman2017-05-19
| | | | | | | | | | | | | | | | | | | | | | | | | | The vm_reserve_va_node struct is essentially a special VM area that can be used for sparse mappings and fixed mappings. The name of this struct is somewhat confusing (as node is typically used for list items). Though this struct is a part of a list it doesn't really make sense to call this a list item since it's much more. Based on that the struct has been renamed to nvgpu_vm_area to capture the actual use of the struct more accurately. This also moves all of the management code of vm areas to a new file devoted solely to vm_area management. Also add a brief overview of the VM architecture. This should help other people follow along the hierachy of ownership and lifetimes in the rather complex MM code.

* 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.
