During Mode 1 reset, the ASIC undergoes a reset cycle and becomes
temporarily inaccessible via PCIe. Any attempt to access MMIO registers
during this window (e.g., from interrupt handlers or other driver threads)
can result in uncompleted PCIe transactions, leading to NMI panics or
system hangs.
To prevent this, set the `no_hw_access` flag to true immediately after
triggering the reset. This signals other driver components to skip
register accesses while the device is offline.
A memory barrier `smp_mb()` is added to ensure the flag update is
globally visible to all cores before the driver enters the sleep/wait
state.

Remove extra multiplication.
CIK GPUs such as Hawaii appear to use PP_TABLE_V0 in which case
the shutdown temperature is hardcoded in smu7_init_dpm_defaults
and is already multiplied by 1000. The value was mistakenly
multiplied another time by smu7_get_thermal_temperature_range.

- Updates PPSMC_Message_Count to 0x5F to account for new messages
2. Adding message mapping for ResetVCN in smu_v13_0_12_ppt.c:
- Maps SMU_MSG_ResetVCN to PPSMC_MSG_ResetVCN

Port of commit 227545b9a0 ("drm/radeon/dpm: Disable sclk
switching on Oland when two 4K 60Hz monitors are connected")
This is an ad-hoc DPM fix, necessary because we don't have
proper bandwidth calculation for DCE 6.
We define "high pixelclock" for SI as higher than necessary
for 4K 30Hz. For example, 4K 60Hz and 1080p 144Hz fall into
this category.
When two high pixel clock displays are connected to Oland,
additionally disable shader clock switching, which results in
a higher voltage, thereby addressing some visible flickering.

Based on some comments in dm_pp_display_configuration
above the crtc_index and line_time fields, these values
are programmed to the SMC to work around an SMC hang
when it switches MCLK.
According to Alex, the Windows driver programs them to:
mclk_change_block_cp_min = 200 / line_time
mclk_change_block_cp_max = 100 / line_time
Let's use the same for the sake of consistency.
Previously we used the watermark values, but it seemed buggy
as the code was mixing up low/high and A/B watermarks, and
was not saving a low watermark value on DCE 6, so
mclk_change_block_cp_max would be always zero previously.

to make it easier to bisect, in case it causes any issues.

The si_upload_smc_data function uses si_write_smc_soft_register
to set some register values in the SMC, and expects the result
to be PPSMC_Result_OK which is 1.
The PPSMC_Result_OK / PPSMC_Result_Failed values are used for
checking the result of a command sent to the SMC.
However, the si_write_smc_soft_register actually doesn't send
any commands to the SMC and returns zero on success,
so this check was incorrect.
Fix that by not checking the return value, just like other
calls to si_write_smc_soft_register.

The SMC can take an excessive amount of time to process some
messages under some conditions.
Background:
Sending a message to the SMC works by writing the message into
the mmSMC_MESSAGE_0 register and its optional parameter into
the mmSMC_SCRATCH0, and then polling mmSMC_RESP_0. Previously
the timeout was AMDGPU_MAX_USEC_TIMEOUT, ie. 100 ms.
Increase the timeout to 200 ms for all messages and to 1 sec for
a few messages which I've observed to be especially slow:
PPSMC_MSG_NoForcedLevel
PPSMC_MSG_SetEnabledLevels
PPSMC_MSG_SetForcedLevels
PPSMC_MSG_DisableULV
PPSMC_MSG_SwitchToSwState
This fixes the following problems on Tahiti when switching
from a lower clock power state to a higher clock state, such
as when DC turns on a display which was previously turned off.
* si_restrict_performance_levels_before_switch would fail
(if the user previously forced high clocks using sysfs)
* si_set_sw_state would fail (always)
It turns out that both of those failures were SMC timeouts and
that the SMC actually didn't fail or hang, just needs more time
to process those.
Add a warning when there is an SMC timeout to make it easier to
identify this type of problem in the future.

Swap mask and value arguments provided to phm_wait_on_register() so that

Found by Linux Verification Center (linuxtesting.org) with Svace static
analysis tool.
In practice this doesn't fix any issues because the only place this
function is used uses the same value for the value and mask.

amdgpu_dpm_set_soft_freq_range() is updated to take in any

ISP and other driver modules to set the min/max clocks. Any
clock specific restrictions are expected to be taken care in

aperture address, it is not compatible with SMU and PSP, it need to be

2. Since FB aperture address will change after switching to new GPU
