For GF119:GV100, we can enable DEGAMMA/CTM/GAMMA. For earlier GPUs, as there is no CTM, having both degamma and gamma is a bit pointless. Later GPUs currently lack an implementation. Signed-off-by:

Pascal was particularly incorrect, as the register changed to be more in the same format as the MMU fault buffers are. Shouldn't have impacted much more than confusing MMU fault log messages. Signed-off-by: -

Signal that the reset sequence has completed. This opcode signals that the software reset sequence has completed. Ordinarily, no actual operations are performed by the opcode. However it allows for possible software work arounds by devinit engines in software agents other than the VBIOS, such as the resman, FCODE, and EFI driver. Signed-off-by:

Absence of a TMDS Info Table is common on Optimus setups where the NVIDIA gpu is not connected directly to any outputs. Reporting an error in this scenario is too harsh. Accordingly, change the error message to an info message. By default the error message also causes a boot flicker for these sytems. Signed-off-by:

On Turing, an input LUT is required to transform inputs in fixed-point formats to FP16 for the internal display pipe. We provide an identity mapping whenever a window is enabled for this reason. HW has error checks to ensure when the input is already FP16, that the input LUT is also disabled. Signed-off-by: -

Make use of the struct_size() helper instead of an open-coded version in order to avoid any potential type mistakes, in particular in the context in which this code is being used. So, replace the following form: sizeof(*kind) + sizeof(*kind->data) * mmu->kind_nr; with: struct_size(kind, data, mmu->kind_nr) This code was detected with the help of Coccinelle. Signed-off-by:

Most importantly per-process address spaces on GPUs that are capable of providing proper isolation has finished baking. This is the base for our softpin implementation, which allows us to support the texture descriptor buffers used by GC7000 series GPUs without a major UAPI extension/rework. Shortlog of notable changes: - code cleanup from Fabio - fix performance counters on GC880 and GC2000 GPUs from Christian - drmP.h header removal from Sam - per process address space support on MMUv2 GPUs from me - softpin support from me Signed-off-by:

Static structure fb_funcs, of type drm_framebuffer_funcs, is used only when it is passed to drm_gem_fb_create_with_funcs() as its last argument. drm_gem_fb_create_with_funcs does not modify its lst argument (fb_funcs) and hence fb_funcs is never modified. Therefore make fb_funcs constant to protect it from further modification. Issue found with Coccinelle. Signed-off-by:

The timestamp and the cb_list are mutually exclusive, the cb_list can only be added to prior to being signaled (and once signaled we drain), while the timestamp is only valid upon being signaled. Both the timestamp and the cb_list are only valid while the fence is alive, and as soon as no references are held can be replaced by the rcu_head. By reusing the union for the timestamp, we squeeze the base dma_fence struct to 64 bytes on x86-64. v2: Sort the union chronologically Suggested-by:

Currently dma_fence_signal() tries to avoid the spinlock and only takes it if absolutely required to walk the callback list. However, to allow for some users to surreptitiously insert lazy signal callbacks that do not depend on enabling the signaling mechanism around every fence, we always need to notify the callbacks on signaling. As such, we will always need to take the spinlock and dma_fence_signal() effectively becomes a clone of dma_fence_signal_locked(). v2: Update the test_and_set_bit() before entering the spinlock. v3: Drop the test_[and_set]_bit() before the spinlock, it's a caller error so expected to be very unlikely.

Before we notify the fence signal callback, we remove the cb from the list. However, since we are processing the entire list from underneath the spinlock, we do not need to individual delete each element, but can simply reset the link and the entire list. Signed-off-by:

Standard DRM panel drivers for several panels used by omapfb2 are now available. Their module name clashes with the modules from drivers/video/fbdev/omap2/omapfb/displays, part of the deprecated omapfb2 fbdev driver. As omapfb2 can only be compiled when the omapdrm driver is disabled, and the DRM panel drivers are useless in that case, make the omapfb2 panels depend on the standard DRM panels being disabled to fix the name clash.

This reverts 67c97fb7 ("dma-buf: add reservation_object_fences helper") dd7a7d1f ("drm/i915: use new reservation_object_fences helper") 0e1d8083 ("dma-buf: further relax reservation_object_add_shared_fence") 5d344f58 ("dma-buf: nuke reservation_object seq number") The scenario that defeats simply grabbing a set of shared/exclusive fences and using them blissfully under RCU is that any of those fences may be reallocated by a SLAB_TYPESAFE_BY_RCU fence slab cache. In this scenario, while keeping the rcu_read_lock we need to establish that no fence was changed in the dma_resv after a read (or full) memory barrier. Signed-off-by:

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. Signed-off-by:
