During i915_request_retire() we decouple the i915_request.hwsp_seqno
from the intel_timeline so that it may be freed before the request is
released. However, we need to warn the compiler that the pointer may
update under its nose.

Implement drm_sched_entity_modify_sched() which modifies existing

userspace changes priority of a ctx/entity then the driver can switch
to the corresponding HW scheduler list for that priority.

We were changing compute ring priority while rings were being used
before every job submission which is not recommended. This patch
sets compute queue priority at mqd initialization for gfx8, gfx9 and
gfx10.
Policy: make queue 0 of each pipe as high priority compute queue
High/normal priority compute sched lists are generated from set of high/normal
priority compute queues. At context creation, entity of compute queue
get a sched list from high or normal priority depending on ctx->priority

Problem Description:
Currently we are checking internal fused rev id with pci rev id. However, fused
internal rev id is the same on all raven2 parts (in which Dali and Pollock were
based on too), thus Pollock detection fails
Fix:
use the pci rev to preform the detection for bandwidth calculations.

Raven provides retimer feature support that requires i2c interaction in
order to make it work well, all settings required for this configuration
are loaded from the Atom bios which include the i2c address. If the
retimer feature is not available, we should abort the attempt to set
this feature, otherwise, it makes the following line return
I2C_CHANNEL_OPERATION_NO_RESPONSE:
i2c_success = i2c_write(pipe_ctx, slave_address, buffer, sizeof(buffer));
...
if (!i2c_success)
ASSERT(i2c_success);
This ends up causing problems with hotplugging HDMI displays on Raven,
and causes retimer settings to warn like so:

This commit reworks the way that we handle i2c write for retimer in the
way that we abort this configuration if the feature is not available in
the device. For debug sake, we kept a simple log message in case the
retimer is not available.

rx id list size = 2+3+16+5*device_count. We will read 16 bytes at a

[why]
Link or DIG BE can't be exposed to a higher stream bandwidth than they
can handle. When DSC is required to fit the stream into the link
bandwidth, DSC has to be programmed during timing programming to ensure
this. Without it, intermittent issues such as black screen after S3 or a
hot-plug can be seen.
[how]
Move DSC programming from enabling stream on link to timing setup.

Be sure to wait for the vma to be in place before we tell the GPU to
execute from the wa batch. Since initialisation is mostly synchronous
(or rather at some point during start up we will need to sync anyway),
we can affort to do an explicit i915_vma_sync() during wa batch
construction rather than check for a required await on every context
switch. (We don't expect to change the wa bb at run time so paying the
cost once up front seems preferrable.)

The current codebase makes use of the zero-length array language
extension to the C90 standard, but the preferred mechanism to declare
variable-length types such as these ones is a flexible array member[1][2],
introduced in C99:
struct foo {
int stuff;
struct boo array[];
};
By making use of the mechanism above, we will get a compiler warning
in case the flexible array does not occur last in the structure, which
will help us prevent some kind of undefined behavior bugs from being
inadvertently introduced[3] to the codebase from now on.
Also, notice that, dynamic memory allocations won't be affected by
this change:
"Flexible array members have incomplete type, and so the sizeof operator
may not be applied. As a quirk of the original implementation of
zero-length arrays, sizeof evaluates to zero."[1]
This issue was found with the help of Coccinelle.

If we stop filling the ELSP due to an incompatible virtual engine
request, check if we should enable the timeslice on behalf of the queue.
This fixes the case where we are inspecting the last->next element when
we know that the last element is the last request in the execution queue,
and so decided we did not need to enable timeslicing despite the intent
to do so!

Due to the ordering of cmpxchg()/dma_fence_signal() inside node_retire(),
we must also use the xchg() as our primary memory barrier to flush the
outstanding callbacks after expected completion of the i915_active.

This workaround is to disable FF DOP Clock gating. The fix
in B0 was backed out due to timing reasons and decided to
be made permanent.

On some platforms such as Elkhart Lake, although we may use DDI D
to drive a connector, we have to use PHY A (Combo Phy PORT A) to
detect the hotplug interrupts as per the spec because there is no
one-to-one mapping between DDIs and PHYs. Therefore, use the
function intel_port_to_phy() which contains the logic for such
mapping(s) to find the correct hpd_pin.
This change should not affect other platforms as there is always
a one-to-one mapping between DDIs and PHYs.
v2:
- Convert the case statements to use PHYs instead of PORTs (Jani)
v3:
- Refactor the function to reduce the number of return statements by
lumping all the case statements together except PHY_F which needs
special handling (Jose)
v4:
- Add a comment describing how the HPD pin value associated with any
port can be retrieved using port or phy enum value. (Jani)
v5:
- Use case ranges instead of individual labels and also normalize the
return statement by adding -PHY_A to the expression (Ville)

something need to do for VCN2.0 enablement on SRIOV:
1)use one dec ring and one enc ring
2)allocate MM table for MMSCH usage
3)implement SRIOV version vcn_start which orgnize vcn programing
with patcket format and implement start mmsch for to run those
packet
4)doorbell is changed for SRIOV
