Fix up inconsistent usage of upper and lowercase letters in "Exynos" name. "EXYNOS" is not an abbreviation but a regular trademarked name. Therefore it should be written with lowercase letters starting with capital letter. The lowercase "Exynos" name is promoted by its manufacturer Samsung Electronics Co., Ltd., in advertisement materials and on website.

2020-01-15drm/vmwgfx: add ioctl for messaging from/to guest userspace to/from hostRoland Scheidegger
Up to now, guest userspace does logging directly to host using essentially the same rather complex port assembly stuff as the kernel. We'd rather use the same mechanism than duplicate it (it may also change in the future), hence add a new ioctl for relaying guest/host messaging (logging is just one application of it).

2019-12-04drm/i915: Introduce DRM_I915_GEM_MMAP_OFFSETAbdiel Janulgue
This is really just an alias of mmap_gtt. The 'mmap offset' nomenclature comes from the value returned by this ioctl which is the offset into the device fd which userpace uses with mmap(2). mmap_gtt was our initial mmap_offset implementation, this extends our CPU mmap support to allow additional fault handlers that depends on the object's backing pages. Note that we multiplex mmap_gtt and mmap_offset through the same ioctl, and use the zero extending behaviour of drm to differentiate between them, when we inspect the flags. To support multiple mmap types on an object we need to support multiple mmap_offsets for an object (each offset in the global device address space corresponding to a unique instance of the object for a file + mmap type). As we drop the simplified drm core idea of a single mmap_offset, we need to provide replacement hooks for the dumb mmap interface as well.

2019-10-29drm/i915/gem: Make context persistence optionalChris Wilson
Our existing behaviour is to allow contexts and their GPU requests to persist past the point of closure until the requests are complete. This allows clients to operate in a 'fire-and-forget' manner where they can setup a rendering pipeline and hand it over to the display server and immediately exit. As the rendering pipeline is kept alive until completion, the display server (or other consumer) can use the results in the future and present them to the user. The compute model is a little different. They have little to no buffer sharing between processes as their kernels tend to operate on a continuous stream, feeding the results back to the client application. These kernels operate for an indeterminate length of time, with many clients wishing that the kernel was always running for as long as they keep feeding in the data, i.e. acting like a DSP. Not all clients want this persistent "desktop" behaviour and would prefer that the contexts are cleaned up immediately upon closure. This ensures that when clients are run without hangchecking (e.g. for compute kernels of indeterminate runtime), any GPU hang or other unexpected workloads are terminated with the process and does not continue to hog resources. The default behaviour for new contexts is the legacy persistence mode, as some desktop applications are dependent upon the existing behaviour. New clients will have to opt in to immediate cleanup on context closure. If the hangchecking modparam is disabled, so is persistent context support -- all contexts will be terminated on closure. We expect this behaviour change to be welcomed by compute users, who have often been caught between a rock and a hard place. They disable hangchecking to avoid their kernels being "unfairly" declared hung, but have also experienced true hangs that the system was then unable to clean up. Naturally, this leads to bug reports.

2019-10-14drm/i915/perf: allow holding preemption on filtered ctxLionel Landwerlin
We would like to make use of perf in Vulkan. The Vulkan API is much lower level than OpenGL, with applications directly exposed to the concept of command buffers (pretty much equivalent to our batch buffers). In Vulkan, queries are always limited in scope to a command buffer. In OpenGL, the lack of command buffer concept meant that queries' duration could span multiple command buffers. With that restriction gone in Vulkan, we would like to simplify measuring performance just by measuring the deltas between the counter snapshots written by 2 MI_RECORD_PERF_COUNT commands, rather than the more complex scheme we currently have in the GL driver, using 2 MI_RECORD_PERF_COUNT commands and doing some post processing on the stream of OA reports, coming from the global OA buffer, to remove any unrelated deltas in between the 2 MI_RECORD_PERF_COUNT. Disabling preemption only apply to a single context with which want to query performance counters for and is considered a privileged operation, by default protected by CAP_SYS_ADMIN. It is possible to enable it for a normal user by disabling the paranoid stream setting. v2: Store preemption setting in intel_context (Chris) v3: Use priorities to avoid preemption rather than the HW mechanism v4: Just modify the port priority reporting function v5: Add nopreempt flag on gem context and always flag requests appropriately, regarless of OA reconfiguration.

Introduce a new perf_ioctl command to change the OA configuration of the active stream. This allows the OA stream to be reconfigured between batch buffers, giving greater flexibility in sampling. We inject a request into the OA context to reconfigure the stream asynchronously on the GPU in between and ordered with execbuffer calls.

2019-10-11drm/omap: add OMAP_BO flags to affect buffer allocationTomi Valkeinen
On SoCs with DMM/TILER, we have two ways to allocate buffers: normal dma_alloc or via DMM (which basically functions as an IOMMU). DMM can map 128MB at a time, and we only map the DMM buffers when they are used (i.e. not at alloc time). If DMM is present, omapdrm always uses DMM. There are use cases that require lots of big buffers that are being used at the same time by different IPs. At the moment the userspace has a hard maximum of 128MB. This patch adds three new flags that can be used by the userspace to solve the situation: OMAP_BO_MEM_CONTIG: The driver will use dma_alloc to get the memory. This can be used to avoid DMM if the userspace knows it needs more than 128M of memory at the same time. OMAP_BO_MEM_DMM: The driver will use DMM to get the memory. There's not much use for this flag at the moment, as on platforms with DMM it is used by default, but it's here for completeness. OMAP_BO_MEM_PIN: The driver will pin the memory at alloc time, and keep it pinned. This can be used to 1) get an error at alloc time if DMM space is full, and 2) get rid of the constant pin/unpin operations which may have some effect on performance. If none of the flags are given, the behavior is the same as currently.

2019-08-15drm/etnaviv: implement softpinLucas Stach
With softpin we allow the userspace to take control over the GPU virtual address space. The new capability is relected by a bump of the minor DRM version. There are a few restrictions for userspace to take into account: 1. The kernel reserves a bit of the address space to implement zero page faulting and mapping of the kernel internal ring buffer. Userspace can query the kernel for the first usable GPU VM address via ETNAVIV_PARAM_SOFTPIN_START_ADDR. 2. We only allow softpin on GPUs, which implement proper process separation via PPAS. If softpin is not available the softpin start address will be set to ~0. 3. Softpin is all or nothing. A submit using softpin must not use any address fixups via relocs.

2019-08-12drm/panfrost: Add support for GPU heap allocationsRob Herring
The midgard/bifrost GPUs need to allocate GPU heap memory which is allocated on GPU page faults and not pinned in memory. The vendor driver calls this functionality GROW_ON_GPF. This implementation assumes that BOs allocated with the PANFROST_BO_NOEXEC flag are never mmapped or exported. Both of those may actually work, but I'm unsure if there's some interaction there. It would cause the whole object to be pinned in memory which would defeat the point of this. On faults, we map in 2MB at a time in order to utilize huge pages (if enabled). Currently, once we've mapped pages in, they are only unmapped if the BO is freed. Once we add shrinker support, we can unmap pages with the shrinker.

2019-08-12drm/panfrost: Add a no execute flag for BO allocationsRob Herring
Executable buffers have an alignment restriction that they can't cross 16MB boundary as the GPU program counter is 24-bits. This restriction is currently not handled and we just get lucky. As current userspace assumes all BOs are executable, that has to remain the default. So add a new PANFROST_BO_NOEXEC flag to allow userspace to indicate which BOs are not executable. There is also a restriction that executable buffers cannot start or end on a 4GB boundary. This is mostly avoided as there is only 4GB of space currently and the beginning is already blocked out for NULL ptr detection. Add support to handle this restriction fully regardless of the current constraints. For existing userspace, all created BOs remain executable, but the GPU VA alignment will be increased to the size of the BO. This shouldn't matter as there is plenty of GPU VA space.

2019-08-08drm/panfrost: Add madvise and shrinker supportRob Herring
Add support for madvise and a shrinker similar to other drivers. This allows userspace to mark BOs which can be freed when there is memory pressure. Unlike other implementations, we don't depend on struct_mutex. The driver maintains a list of BOs which can be freed when the shrinker is called. Access to the list is serialized with the shrinker_lock.
