Our debug struct has the min_disp_clk_khz and min_dpp_clk_khz options,
which we ignore in the DCN32. This commit introduces those checks and
the necessary calculation.

[Why]
Several issues were discovered that caused link
training to fail when an LTTPR device is
connected downstream for the fixed VS sequence.
[How]
The following were added:
- workaround to configure AUX timeout
for fixed VS sequence
- additional delay before disabling
fixed VS intercept
- detection of fixed VS deadlock state and
performing DPCD sequence to recover

[why]
Only on VG, if external display is disconnected during S3 suspend, the
internal panel doesn't light up on resume because we set the power state
using an unsupported DPCD register SET_POWER. To check the register is
supported, we need to check SET_POWER_CAPABLE first which is
eDP-specific DPCD register field.

Check the SET_POWER_CAPABLE register field and decide the control of the
eDP power state based on the read register value.

[Why]
Observe that we have several problems while releasing remote dc_sink
under mst cases.
- When unplug mst branch device from the source, we now try to free all
remote dc_sinks in dm_helpers_dp_mst_stop_top_mgr(). However, there are
bugs while we're releasing dc_sinks here. First of all,
link->remote_sinks[] array get shuffled within
dc_link_remove_remote_sink(). As the result, increasing the array index
within the releasing loop is wrong. Secondly, it tries to call
dc_sink_release() to release the dc_sink of the same aconnector every
time in the loop. Which can't release dc_sink of all aconnector in the
mst topology.
- There is no code path for us to release remote dc_sink for disconnected
sst monitor which unplug event is notified by CSN sideband message. Which
means we'll use stale dc_sink data to represent later on connected
monitor. Also, has chance to break the maximum remote dc_sink number
constraint.
[How]
Distinguish unplug event of mst scenario into 2 cases.
* Unplug sst/legacy stream sink off the mst topology
- Release related remote dc_sink in detec_ctx().
* Unplug mst branch device off the mst topology
- Release related remote dc_sink in early_unregister()

This reverts commit 3c4d55c9b9becedd8d31a7c96783a364533713ab.
Revert the commit because:
- It's incomplete of the function dm_set_dpms_off() for mst case. For
stream sinks whithin the same mst topology, they share the same dc_link.
dm_set_dpms_off() tries to update one mst stream only which is
incomplete.
- Setting dpms off should be triggered by usermode. Besdies, it seems
usermode does release relevant resource for mst & non-mst case when
unplug connecotr now.

This reverts commit 035f54969bb2c1a5ced52f43e4ef393e0c0f6bfa.
The reverted commit was trying to fix side effect brought by
commit 3c4d55c9b9be ("drm/amd/display: turn DPMS off on connector unplug")
However,
* This reverted commit will have mst case never call dm_set_dpms_off()
which conflicts the idea of original commit 3c4d55c9b9be ("drm/amd/display: turn DPMS off on connector unplug")
That's due to dm_crtc_state is always null since the input parameter
aconnector is the root device (source) of mst topology. It's not an
end stream sink within the mst topology.
* Setting dpms off should be triggered by usermode. Besdies, it seems
usermode does release relevant resource for mst & non-mst case when
unplug connecotr now. Which means we no longer need both commits now:
commit 3c4d55c9b9be ("drm/amd/display: turn DPMS off on connector unplug")
commit 035f54969bb2 ("drm/amd/display: Add flag to detect dpms force off during HPD")

Certain GL unit tests for large textures can cause problems
with the OOM killer since there is no way to link this memory
to a process. This was originally mitigated (but not necessarily
eliminated) by limiting the GTT size. The problem is this limit
is often too low for many modern games so just make the limit 1/2
of system memory. The OOM accounting needs to be addressed, but
we shouldn't prevent common 3D applications from being usable
just to potentially mitigate that corner case.
Set default GTT size to max(3G, 1/2 of system ram) by default.
v2: drop previous logic and default to 3/4 of ram
v3: default to half of ram to align with ttm
v4: fix spelling in comment (Kent)

The device is created, and then there is a check if a driver succesfully
bound to it. In event of failing the bind (e.g. failure in cxl_port_probe())
the device is left registered. When a bus rescan later occurs, fresh
devices are created leading to a multiple device representing the same
underlying hardware. Bad things may follow and at very least we have far too many
devices.
Fix by ensuring autoremove is registered if the device create succeeds,
but doesn't depend on sucessful binding to a driver.

Calling synchronize_irq() right before free_irq() is quite useless. On one
hand the IRQ can easily fire again before free_irq() is entered, on the
other hand free_irq() itself calls synchronize_irq() internally (in a race
condition free way), before any state associated with the IRQ is freed.

Add ability to change speed through ethtool -s <interface> speed <speed in Mb>
Driver advertises all link modes that support requested speed.
Autoneg must be set off e.g.:
ethtool -s <interface> autoneg off speed <speed in Mb>.
Add helper function that translate speed in Mb to
enum i40e_aq_link_speed and compare it to supported speeds from
given ethtool_link_ksettings. Add in i40e_set_link_ksettings hold
for requested speed and set copy_ks.base.speed to safe_ks.base.speed
to be sure that user is not changing unsupported setting.
In i40e_speed_to_link_speed compare requested speed with supported
speeds. Set speed to requested speed.

In current implementation ice_update_phy_type enables all link modes
for selected speed. This approach doesn't work for 1000M speeds,
because both copper (1000baseT) and optical (1000baseX) standards
cannot be enabled at once.
Fix this, by adding the function `ice_set_phy_type_from_speed()`
for 1000M speeds.

Adding two filters with same matching criteria ends up with
one rule in hardware with act = ICE_FWD_TO_VSI_LIST.
In order to remove them properly we have to keep the
information about vsi handle which is used in VSI bitmap
(ice_adv_fltr_mgmt_list_entry::vsi_list_info::vsi_map).

There are sleep in atomic context bugs when uploading device dump
data in mwifiex. The root cause is that dev_coredumpv could not
be used in atomic contexts, because it calls dev_set_name which
include operations that may sleep. The call tree shows execution
paths that could lead to bugs:
(Interrupt context)
fw_dump_timer_fn
mwifiex_upload_device_dump
dev_coredumpv(..., GFP_KERNEL)
dev_coredumpm()
kzalloc(sizeof(*devcd), gfp); //may sleep
dev_set_name
kobject_set_name_vargs
kvasprintf_const(GFP_KERNEL, ...); //may sleep
kstrdup(s, GFP_KERNEL); //may sleep
The corresponding fail log is shown below:

[ 135.389205] usb 1-1: == mwifiex dump information to /sys/class/devcoredump end
This patch uses delayed work to replace timer and moves the operations
that may sleep into a delayed work in order to mitigate bugs, it was
tested on Marvell 88W8801 chip whose port is usb and the firmware is
usb8801_uapsta.bin. The following is the result after using delayed
work to replace timer.

[ 135.043344] usb 1-1: == mwifiex dump information to /sys/class/devcoredump end
As we can see, there is no bug now.

The dev_coredumpv() and dev_coredumpm() could not be used in atomic
context, because they call kvasprintf_const() and kstrdup() with
GFP_KERNEL parameter. The process is shown below:
dev_coredumpv(.., gfp_t gfp)
dev_coredumpm(.., gfp_t gfp)
dev_set_name
kobject_set_name_vargs
kvasprintf_const(GFP_KERNEL, ...); //may sleep
kstrdup(s, GFP_KERNEL); //may sleep
This patch removes gfp_t parameter of dev_coredumpv() and dev_coredumpm()
and changes the gfp_t parameter of kzalloc() in dev_coredumpm() to
GFP_KERNEL in order to show they could not be used in atomic context.
