* gpu: nvgpu: Use only contig CBCsAlex Waterman2017-11-08
| | | | | | | | | | | | | | | | | | | | | | | | | | | Modify the LTC code to only use a contiguous CompBit Cache (CBC). The original code had two allocation schemes: "physical" and "virtual" - what they meant was virtually contiguous or physically contiguous. The CBC must appear contiguous to the GPU be it either from the IOMMU or from physical pages allocated contiguously. This change makes the CBC get allocated with the FORCE_CONTIGUOUS flag if the GPU is not IOMMU'able. If we can get contiguous mem with the IOMMU then no need to force the underlying pages to be contiguous. However, not all GPUs may be IOMMU'able so we do need to handle that case. Also delete the gk20a/ltc_gk20a.[ch] code. All that remained in these files was the CBC alloc functions which were completely chip agnostic. As a result these functions were consolidated and moved to common/ltc.c.

| | | | | | | | | | | | | | | | | | | | Request explicitly contiguous DMA memory for large page directory allocations. Large in this case means greater than PAGE_SIZE.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | -Power features should be enabled only if s/w flags xxcg_enabled are set for corresponding features. These flags control whether feature should be kept disabled in the hardware or not. For disable case, register programming will happen for CG registers and they will be set to disabled. For ELPG, init command will be sent to PMU, but “ELPG_ALLOW” will not be sent to PMU. Also these flags can be modified using sysfs. These flags are noop if corresponding can_xxxg flags are set to flase. S/w flags can_xxxg tell the ability of platform to support a power feature and cannot be modified by syfs. Setting these flags to false will avoid any HW register write or init sequence for the power feature from executing. For ELPG, no commands will be sent to PMU. -g->elcg_enabled flag should not be modified here. It should be modified only by sysfs. This will be cleaned up in follow up implementation where debug session will have some kind of lock where it will keep power features disabled as long as it wants to. Debugger cannot rely on this flag to keep power management disabled as these flags can be changed from sysfs. Due to this issue someone can easily break debugging session by accidentally changing something in sysfs.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | Remove the always true field 'user_mapped' from the mapped_buf struct. All mapped_bufs are mapped by a user request since they always originate from a dma_buf (for Linux, that is). As such there is a fair amount of logic that could be deleted. Linux specific: the own_mem_ref field was also be deleted. The logic of only storing a dma_buf ref when the buffer is mapped for the first time by a user is easy: when the mapped buffer is found in the map cache release the outstanding dma_buf ref taken earlier on in the map path. If the map cache does not have the buffer simply let the higher level map code keep the dma_buf ref. The dma_buf ref is released when the nvgpu_vm_unmap_system() call-back is called by the unmap path.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Re-organize the unmap code to be better split between OS specific requirements and common core requirements. The new code flow works as follows: nvgpu_vm_unmap() Is the primary entrance to the unmap path. It takes a VM and a GPU virtual address to unmap. There's also an optional batch mapping struct. This function is responsible for making sure there is a real buffer and that if it's being called on a fixed mapping then the mapping will definitely be freed (since buffers are ref-counted). Then this function decrements the ref-count and returns. If the ref-count hits zero then __nvgpu_vm_unmap_ref() is called which just calls __nvgpu_vm_unmap() with the relevant batch struct if present. This is where the real work is done. __nvgpu_vm_unmap() clears the GMMU mapping, removes the mapped buffer from the various lists and trees it may be in and then calls the nvgpu_vm_unmap_system() function. This function handles any OS specific stuff and must be defined by all VM OS implementations. There's a a short cut used by some other core VM code to free mappings without going through nvgpu_vm_map(). Mostly they just directly decrement the mapping ref-count which can then call __nvgpu_vm_unmap_ref() if the ref-count hits zero.
