It can be useful to have a single ioctl to create a context with all
the initial parameters instead of a series of create + setparam + setparam
ioctls. This extension to create context allows any of the parameters
to be passed in as a linked list to be applied to the newly constructed
context.

An idea for extending uABI inspired by Vulkan's extension chains.
Instead of expanding the data struct for each ioctl every time we need
to add a new feature, define an extension chain instead. As we add
optional interfaces to control the ioctl, we define a new extension
struct that can be linked into the ioctl data only when required by the
user. The key advantage being able to ignore large control structs for
optional interfaces/extensions, while being able to process them in a
consistent manner.
In comparison to other extensible ioctls, the key difference is the
use of a linked chain of extension structs vs an array of tagged
pointers. For example,
struct drm_amdgpu_cs_chunk {
__u32 chunk_id;
__u32 length_dw;
__u64 chunk_data;
};
struct drm_amdgpu_cs_in {
__u32 ctx_id;
__u32 bo_list_handle;
__u32 num_chunks;
__u32 _pad;
__u64 chunks;
};
allows userspace to pass in array of pointers to extension structs, but
must therefore keep constructing that array along side the command stream.
In dynamic situations like that, a linked list is preferred and does not
similar from extra cache line misses as the extension structs themselves
must still be loaded separate to the chunks array.
v2: Apply the tail call optimisation directly to nip the worry of stack
overflow in the bud.
v3: Defend against recursion.
v4: Fixup local types to match new uabi
Opens:
- do we include the result as an out-field in each chain?
struct i915_user_extension {
__u64 next_extension;
__u64 name;
__s32 result;
__u32 mbz; /* reserved for future use */
};
* Undecided, so provision some room for future expansion.

Black screens or artifacting can occur when enabling FreeSync outside
of the supported range of the monitor. This can happen since the

There was previously a fix that prevented this from happening in the

If we are already in the desired write domain of a set-domain ioctl,
then there is nothing for us to do and we can quickly return back to
userspace, avoiding any lock contention. By recognising that the
write_domain is always a subset of the read_domains, and excluding the
no-op case of requiring 0 read_domains in the ioctl, we can infer if the
current write_domain matches the target read_domains, there is nothing
for us to do.
Secondary aspect of this is that we undo the arbitrary fetching and
potential flushing of all pages for a set-domain(.write=CPU) call on a
fresh object -- which was introduced simply because we do the get-pages
before taking the struct_mutex.

When we return pages to the system, we ensure that they are marked as
being in the CPU domain since any external access is uncontrolled and we
must assume the worst. This means that we need to always flush the pages
on acquisition if we need to use them on the GPU, and from the beginning
have used set-domain. Set-domain is overkill for the purpose as it is a
general synchronisation barrier, but our intent is to only flush the
pages being swapped in. If we move that flush into the pages acquisition
phase, we know then that when we have obj->mm.pages, they are coherent
with the GPU and need only maintain that status without resorting to
heavy handed use of set-domain.
The principle knock-on effect for userspace is through mmap-gtt
pagefaulting. Our uAPI has always implied that the GTT mmap was async
(especially as when any pagefault occurs is unpredicatable to userspace)
and so userspace had to apply explicit domain control itself
(set-domain). However, swapping is transparent to the kernel, and so on
first fault we need to acquire the pages and make them coherent for
access through the GTT. Our use of set-domain here leaks into the uABI
that the first pagefault was synchronous. This is unintentional and
baring a few igt should be unoticed, nevertheless we bump the uABI
version for mmap-gtt to reflect the change in behaviour.
Another implication of the change is that gem_create() is presumed to
create an object that is coherent with the CPU and is in the CPU write
domain, so a set-domain(CPU) following a gem_create() would be a minor
operation that merely checked whether we could allocate all pages for
the object. On applying this change, a set-domain(CPU) causes a clflush
as we acquire the pages. This will have a small impact on mesa as we move
the clflush here on !llc from execbuf time to create, but that should
have minimal performance impact as the same clflush exists but is now
done early and because of the clflush issue, userspace recycles bo and
so should resist allocating fresh objects.
Internally, the presumption that objects are created in the CPU
write-domain and remain so through writes to obj->mm.mapping is more
prevalent than I expected; but easy enough to catch and apply a manual
flush.
For the future, we should push the page flush from the central
set_pages() into the callers so that we can more finely control when it
is applied, but for now doing it one location is easier to validate, at
the cost of sometimes flushing when there is no need.

D71 consists of a number of Register Blocks, every Block controls a

its type and pipeline information.
GCU (Global Control Unit) is the first Block which describe the global

pipeline supported.
So the d71_enum_resources parsed GCU and create pipeline according
the GCU configuration, and then iterate and detect the blocks that
indicated by the GCU and block_header.
And this change also added two struct d71_dev/d71_pipeline to extend

There has unfortunately been a conflict with the following 3 commits:
commit e9961ab95af81b8d29054361cd5f0c575102cf87
Author: Ayan Kumar Halder <ayan.halder@arm.com>
Date: Fri Nov 9 17:21:12 2018 +0000
drm: Added a new format DRM_FORMAT_XVYU2101010
commit 7ba0fee247ee7a36b3bfbed68f6988d980aa3aa3
Author: Brian Starkey <brian.starkey@arm.com>
Date: Fri Oct 5 10:27:00 2018 +0100
drm/fourcc: Add AFBC yuv fourccs for Mali
and
commit 50bf5d7d595fd0705ef3785f80e679b6da501e5b
Author: Swati Sharma <swati2.sharma@intel.com>
Date: Mon Mar 4 17:26:33 2019 +0530
drm: Add Y2xx and Y4xx (xx:10/12/16) format definitions and fourcc
Unfortunately gcc didn't warn about the redefinitions, because the
double defines were the set to same value, and gcc apparently no longer
warns about that.
Fix this by using new XYVU for i915, without alpha, and making the
Y41x definitions match msdn, with alpha.
Fortunately we caught it early, and the conflict hasn't even landed in
drm-next yet.

This patch enables gfxoff and stutter mode again, since we take more testing on
raven series. For raven2 and picasso, we can enable it directly. And for raven,
we need check the RLC/SMC ucode version cannot be less than #531/0x1e45.
v2: add smc version checking for raven.

The if statement it mentions as potentially problematic is currently
always true because the read_smc_arg callback is assigned at the
bottom of this file but Clang can't tell that. If the callback were
ever to disappear, num_of_levels would never be initialized. Just
zero initialize it to ensure that the intent behind this code
remains the same.

We want DRM planes to be initialized in the following order:
- primary planes
- overlay planes
- cursor planes
to support existing userspace expectations for plane z-ordering. This
means that we also need to register CRTCs after all planes have been
initialized since overlay planes can be placed on any CRTC.
So the only reason why we have the mode_info->planes list is to
remember the primary planes for use later when we need to register
the CRTC.
Overlay planes have no purpose being in this list. DRM will cleanup
any planes that we've registered for us, so the only planes that need to
be explicitly cleaned up are the ones that have failed to register.
By dropping the explicit free on every plane in the mode_info->planes
list this patch also fixes a double-free in the case where we fail to
initialize only some of the planes.

[Why]
We need arbitrary read/write over DP AUX DPCD
for debugging
[How]
Three debugfs entries
Set the target address by writing to
"aux_dpcd_address"
(The first four bytes written are used)
Set the transaction size in bytes by writing to
"aux_dpcd_size"
(The first four bytes written are used)
Start a transaction by reading/writing
"aux_dpcd_data"
Do note: there is no concerrency protection at all
Accessing these entries in quick succession can lead
to strange behaviour
