2021-07-08drm/i915: Drop the CONTEXT_CLONE API (v2)Jason Ekstrand-13/+3
This API allows one context to grab bits out of another context upon creation. It can be used as a short-cut for setparam(getparam()) for things like I915_CONTEXT_PARAM_VM. However, it's never been used by any real userspace. It's used by a few IGT tests and that's it. Since it doesn't add any real value (most of the stuff you can CLONE you can copy in other ways), drop it. There is one thing that this API allows you to clone which you cannot clone via getparam/setparam: timelines. However, timelines are an implementation detail of i915 and not really something that needs to be exposed to userspace. Also, sharing timelines between contexts isn't obviously useful and supporting it has the potential to complicate i915 internally. It also doesn't add any functionality that the client can't get in other ways. If a client really wants a shared timeline, they can use a syncobj and set it as an in and out fence on every submit. v2 (Jason Ekstrand): - More detailed commit message Signed-off-by: Jason Ekstrand <jason@jlekstrand.net> Reviewed-by: Daniel Vetter <daniel.vetter@ffwll.ch> Signed-off-by: Daniel Vetter <daniel.vetter@ffwll.ch> Link: https://patchwork.freedesktop.org/patch/msgid/20210708154835.528166-7-jason@jlekstrand.net
2021-07-08drm/i915: Drop I915_CONTEXT_PARAM_NO_ZEROMAPJason Ekstrand-0/+4
The idea behind this param is to support OpenCL drivers with relocations because OpenCL reserves 0x0 for NULL and, if we placed memory there, it would confuse CL kernels. It was originally sent out as part of a patch series including libdrm [1] and Beignet [2] support. However, the libdrm and Beignet patches never landed in their respective upstream projects so this API has never been used. It's never been used in Mesa or any other driver, either. Dropping this API allows us to delete a small bit of code.

2021-07-08drm/i915: Drop I915_CONTEXT_PARAM_RINGSIZEJason Ekstrand-18/+2
This reverts commit 88be76cdafc7 ("drm/i915: Allow userspace to specify ringsize on construction"). This API was originally added for OpenCL but the compute-runtime PR has sat open for a year without action so we can still pull it out if we want. I argue we should drop it for three reasons: 1. If the compute-runtime PR has sat open for a year, this clearly isn't that important. 2. It's a very leaky API. Ring size is an implementation detail of the current execlist scheduler and really only makes sense there. It can't apply to the older ring-buffer scheduler on pre-execlist hardware because that's shared across all contexts and it won't apply to the GuC scheduler that's in the pipeline. 3. Having userspace set a ring size in bytes is a bad solution to the problem of having too small a ring. There is no way that userspace has the information to know how to properly set the ring size so it's just going to detect the feature and always set it to the maximum of 512K. This is what the compute-runtime PR does. The scheduler in i915, on the other hand, does have the information to make an informed choice. It could detect if the ring size is a problem and grow it itself. Or, if that's too hard, we could just increase the default size from 16K to 32K or even 64K instead of relying on userspace to do it. Let's drop this API for now and, if someone decides they really care about solving this problem, they can do it properly.

2021-06-04drm/panfrost: Add AFBC_FEATURES parameterAlyssa Rosenzweig-0/+1
The value of the AFBC_FEATURES register is required by userspace to determine AFBC support on Bifrost. A user on our IRC channel (#panfrost) reported a workload that raised a fault on one system's Mali G31 but worked flawlessly with another system's Mali G31. We determined the cause to be missing AFBC support on one vendor's Mali implementation -- it turns out AFBC is optional on Bifrost! Whether AFBC is supported or not is exposed in the AFBC_FEATURES register on Bifrost, which reads back as 0 on Midgard. A zero value indicates AFBC is fully supported, provided the architecture itself supports AFBC, allowing backwards-compatibility with Midgard. Bits 0 and 15 indicate that AFBC support is absent for texturing and rendering respectively. The user experiencing the fault reports that AFBC_FEATURES reads back 0x10001 on their system, confirming the architectural lack of AFBC. Userspace needs this parameter to know to disable AFBC on that chip, and perhaps others. v2: Fix typo from copy-paste fail. v3: Bump the UABI version. This commit was cherry-picked from another series so chalking this up to a rebase fail.

These are 16 bits per color channel unsigned normalized formats. They are supported by at least AMD display hw, and suitable for direct scanout of Vulkan swapchain images in the format VK_FORMAT_R16G16B16A16_UNORM.

2021-05-21drm/amdgpu: Add new placement for preemptible SG BOsFelix Kuehling-0/+4
SG BOs such as dmabuf imports and userptr BOs do not consume system resources directly. Instead they point to resources owned elsewhere. They typically get evicted by DMABuf move notifiers of MMU notifiers. If those notifiers don't need to wait for hardware fences (i.e. the SG BOs are used in a preemptible context), then we don't need to limit them to the GTT size and we don't need TTM to evict them. Create a new placement for such preemptible SG BOs that does not impose artificial size limits and TTM evictions.

This is needed to support various upcoming usecases. v2:(Chris) - Use separate ioctl number for gem_create_ext, instead of hijacking the existing gem_create ioctl, otherwise we run into the issue with being unable to detect if the kernel supports the new extension behaviour. - We now have gem_create_ext.flags, which should be zeroed. - I915_GEM_CREATE_EXT_SETPARAM value is now zero, since this is the index into our array of extensions. - Setup a "vanilla" object which we can directly apply our extensions to. v3:(Daniel & Jason) - drop I915_GEM_CREATE_EXT_SETPARAM. Instead just have each extension do one thing only, instead of generic setparam which can cover various use cases. - add some kernel-doc.
