Some monitors apparently forget to mark any mode as preferred in the
EDID. In this particular case we have a very generic looking ID
"PNP Model 0 Serial Number 4" / "LVDS 800x600" so a specific quirk
doesn't seem particularly wise. Also the quirk we have
(EDID_QUIRK_FIRST_DETAILED_PREFERRED) is actually defunct so we'd
have to fix it first.
When there is no preferred mode we currently fall back to the VBT.
That approach fails us here as the VBT mode is 1024x768 whereas
the panel resolution is 800x600. So instead of falling back to the
VBT when there is no preferred mode let's just pick the first
probed mode. Only if the EDID provided no modes we fall back to
the VBT.
For this machine the VBIOS would appear to select the 800x600
60Hz EST mode rather than the first detailed mode (which is
the new fallback will pick). The two modes differ only by
having opposite sync polarities, which does not seem to matter
to the panel in question.

Previously, our view has been always to run the engines independently
within a context. (Multiple engines happened before we had contexts and
timelines, so they always operated independently and that behaviour
persisted into contexts.) However, at the user level the context often
represents a single timeline (e.g. GL contexts) and userspace must
ensure that the individual engines are serialised to present that
ordering to the client (or forgot about this detail entirely and hope no
one notices - a fair ploy if the client can only directly control one
engine themselves ;)
In the next patch, we will want to construct a set of engines that
operate as one, that have a single timeline interwoven between them, to
present a single virtual engine to the user. (They submit to the virtual
engine, then we decide which engine to execute on based.)
To that end, we want to be able to create contexts which have a single
timeline (fence context) shared between all engines, rather than multiple
timelines.
v2: Move the specialised timeline ordering to its own function.

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.

The futex code requires that the user space addresses of futexes are 32bit
aligned. sys_futex() checks this in futex_get_keys() but the robust list
code has no alignment check in place.
As a consequence the kernel crashes on architectures with strict alignment
requirements in handle_futex_death() when trying to cmpxchg() on an
unaligned futex address which was retrieved from the robust list.

Empty chunk do not have a bo associated with them so no need to pin/unpin
on suspend/resume.
This fix suspend/resume on 5.1rc1 when NOUVEAU_SVM is enabled.

The "size" variable is unsigned. We never pass invalid sizes to this
function and we already used it as an array offset earlier so it's
too late to check here.

This reverts commit 9b638f9751308ae3ae8f28e0c6e9decffd97f5f9.
Adding this to the mapping is complete nonsense and the whole

and should be reverted for now.

Separate out all functions for SDMA and CPU based page table

This way we can keep most of the complexity of those from the
