drm/tegra: Changes for v4.18-rc1 This set enables IOMMU support in the gr2d and gr3d drivers and adds support for the zpos property on older Tegra generations. It also enables scaling filters and incorporates some rework to eliminate a private wrapper around struct drm_framebuffer. The remainder is mostly a random assortment of fixes and cleanups, as well as some preparatory work for destaging the userspace ABI, which is almost ready and is targetted for v4.19-rc1.

So what we have for this cycle is a bit of spring cleaning with removal of unused register logging code and getting rid of the license text in favor of SPDX, a few smaller MMU handling improvements and a timeout calculation change, fixing premature fence wait timeouts after 50 days of uptime.

Document the userspace ABI with kerneldoc to provide some information on how to use it. v3: - reword description of arrays and array lengths v2: - keep GEM object creation flags for ABI compatibility - fix typo in struct drm_tegra_syncpt_incr kerneldoc - fix typos in struct drm_tegra_submit kerneldoc - reworded some descriptions as suggested Reviewed-by:

Userspace needs to know the version of the interface implemented by a client so it can create the proper command streams. Allow individual drivers to store this version along with the client so that it can be returned to userspace upon opening a channel. Acked-by:

Currently only the DRM_MODE_REFLECT_Y rotation is supported. The driver already supports reflection on the Y axis via a custom flag which is not very useful because it requires custom userspace. Add the standard rotation property that supports 0 degree rotation and Y axis reflection for primary and overlay planes to provide a better interface than the custom flag. v2: keep custom flag for ABI compatibility (Dmitry) Reviewed-by:

The job submission userspace ABI doesn't support this and there are no plans to implement it, so all of this code is dead and can be removed. Reviewed-by:

This replaces the repetitive GPL-2.0 license text in code and header files with the SPDX tags. Generated hardware headers aren't changed, as any changes there need to be done in the upstream rnndb repository. Signed-off-by:

MMUv2 supports up to 40 bits of physical address by folding the upper 8 bits into bits [4:11] of the PTE. Signed-off-by: -

With etnaviv not being tied into the IOMMU framework anymore, the MMU functions will only be called under sleeping locks. Thus we are able to allocate the memory for the 2nd level page tables on demand without having to deal with memory allocation in atomic context. This speeds up driver intitialization on MMUv2 GPU cores, as we don't need to preallocate all the page table memory and also reduces memory consumption for most workloads, as most of them won't use the full GPU virtual address space.

We are likely to write multiple page entries at once and already ensure proper write buffer flushing before GPU submit, so this improves CPU time usage in the submit path without any downsides. Signed-off-by:

I'm not aware of any case where tracing GPU register manipulation at the kernel level would have been useful. It only adds more indirections and adds to the code size. Signed-off-by:

This was useful on MMUv1 GPUs, which don't generate proper faults, when the GPU write caches weren't fully understood and not properly handled by the kernel driver. As this has been fixed for quite some time, the cycling though the MMU address space needlessly spreads out the MMU mappings. Signed-off-by: -

The old way did clamp the jiffy conversion and thus caused the timeouts to become negative after some time. Also it didn't work with userspace which actually fills the upper 32bits of the 64bit timestamp value. clock_gettime() is 32-bit on 32-bit architectures. Using 64-bit timespec math, like we do in this commit, means that when a wrap occurs, the specified timeout goes into the past and we can't request a timeout in the future. As the Linux implementation of CLOCK_MONOTONIC is reasonable and starts at 0, the first such timer wrap will occur after approx. 68 years of system uptime. Signed-off-by:

The compiler is complaining with the following errors: drivers/gpu/host1x/cdma.c:94:48: error: passing argument 3 of ‘dma_alloc_wc’ from incompatible pointer type [-Werror=incompatible-pointer-types] drivers/gpu/host1x/cdma.c:113:48: error: passing argument 3 of ‘dma_alloc_wc’ from incompatible pointer type [-Werror=incompatible-pointer-types] The expected pointer type of the third argument to dma_alloc_wc() is dma_addr_t but phys_addr_t is passed. Change the phys member of struct push_buffer to be dma_addr_t so that we pass the correct type to dma_alloc_wc(). Also check pb->mapped for non-NULL in the destroy function as that is the right way of checking if dma_alloc_wc() was successful. Signed-off-by:

The main thing here is the addition of support for Volta GV100 GPUs, everything else basically restructuring display / graphics init code to make it possible to fit Volta support in more nicely. There's a bunch of improvements/fixes scattered in there for earlier GPUs too, particularly graphics engine init on all GPUs from Fermi onwards. Signed-off-by:

It's better to use "list_for_each_entry_from_reverse" for iterating list than "for loop" as it makes the code more clear to read. This patch replace "for loop" with "list_for_each_entry_from_reverse" and "start" variable with "cstate" which helps in refactoring the code and also "cstate" variable is more commonly used in the other functions. changes in v2: "start" variable is removed, before "cstate" variable was removed but "cstate" is more common so preferred "cstate" over "start".
