* gpu: nvgpu: add safe channel id lookupKonsta Holtta2019-02-05
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Add gk20a_channel_from_id() to retrieve a channel, given a raw channel ID, with a reference taken (or NULL if the channel was dead). This makes it harder to mistakenly use a channel that's dead and thus uncovers bugs sooner. Convert code to use the new lookup when applicable; work remains to convert complex uses where a ref should have been taken but hasn't. The channel ID is also validated against FIFO_INVAL_CHANNEL_ID; NULL is returned for such IDs. This is often useful and does not hurt when unnecessary. However, this does not prevent the case where a channel would be closed and reopened again when someone would hold a stale channel number. In all such conditions the caller should hold a reference already. The only conditions where a channel can be safely looked up by an id and used without taking a ref are when initializing or deinitializing the list of channels.

This is Mode-B context switch of PMs with Mode-E streamout on one context.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

* gpu: nvgpu: fix channel unbind sequence from TSGDeepak Nibade2017-09-15
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | We right now remove a channel from TSG list and disable all the channels in TSG while removing a channel from TSG With this sequence if any one channel in TSG is closed, rest of the channels are set as timed out and cannot be used anymore We need to fix this sequence as below to allow removing a channel from active TSG so that rest of the channels can still be used - disable all channels of TSG - preempt TSG - check if CTX_RELOAD is set if support is available if CTX_RELOAD is set on channel, it should be moved to some other channel - check if FAULTED is set if support is available - if NEXT is set on channel then it means channel is still active print out an error in this case for the time being until properly handled - remove the channel from runlist - remove channel from TSG list - re-enable rest of the channels in TSG - clean up the channel (same as regular channels) Add below fifo operations to support checking channel status g->ops.fifo.tsg_verify_status_ctx_reload g->ops.fifo.tsg_verify_status_faulted Define ops.fifo.tsg_verify_status_ctx_reload operation for gm20b/gp10b/gp106 as gm20b_fifo_tsg_verify_status_ctx_reload() This API will check if channel to be released has CTX_RELOAD set, if yes CTX_RELOAD needs to be moved to some other channel in TSG Remove static from channel_gk20a_update_runlist() and export it Bug 200327095 Change-Id: I0dd4be7c7e0b9b759389ec12c5a148a4b919d3e2 Signed-off-by: Deepak Nibade <dnibade@nvidia.com> Reviewed-on: https://git-master.nvidia.com/r/1560637 Reviewed-by: svc-mobile-coverity <svc-mobile-coverity@nvidia.com> GVS: Gerrit_Virtual_Submit Reviewed-by: Seshendra Gadagottu <sgadagottu@nvidia.com> Reviewed-by: Terje Bergstrom <tbergstrom@nvidia.com>

* 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.
