In function enable_stream_features(), the variable "old_downspread.raw" could be uninitialized if core_link_read_dpcd() fails, however, it is used in the later if statement, and further, core_link_write_dpcd() may write random value, which is potentially unsafe.

It's not only supported by HG/PX laptops. It's supported by all dGPUs which supports BOCO/BACO functionality (runtime D3). BOCO - Bus Off, Chip Off. The entire chip is powered off. This is controlled by ACPI. BACO - Bus Active, Chip Off. The chip still shows up on the PCI bus, but the device itself is powered down. v2: fix missed HG/PX reference Reviewed-by: -

== Description == Setting values of pm attributes through sysfs should not be allowed in SRIOV mode. These calls will not be processed by FW anyway, but error handling on sysfs level should be improved. == Changes == This patch prohibits performing of all set commands in SRIOV mode on sysfs level. It offers better error handling as calls that are not allowed will not be propagated further. == Test == Writing to any sysfs file in passthrough mode will succeed. Writing to any sysfs file in ONEVF mode will yield error: "calling process does not have sufficient permission to execute a command". Signed-off-by:

[why] There will be a series of re-arch changes in Link Resource Management. They are more and more muxable link resource objects and the resource is insufficient for a one to one allocation to all links created. Therefore a link resource sharing logic is required to determine which link should use certain link resource. This commit is the first one in this series that starts by defining a link resource struct, this struct will be available to all interfaces that need to perform link programming sequence. In later commits, we will granduately decouple link resource objects out of dc link. So instead of access a link resource from dc link. Current link's resource can be accessible through pipe_ctx->link_res during commit, or by calling dc_link_get_cur_link_res function with current link passed in after commit. Tested-by:

[Why] Stutter period won't be less than 5000.0, but if PSR is enabled then we can potentially enter Z9 when MPO is enabled. SMU will try to enter Z9 too early in these cases (before PSR is enabled) and we'll see underflow.

If the event guard is enabled and VF doesn't receive an ack from PF for full access, the guest driver load crashes.

drm/amdgpu: Call amdgpu_device_unmap_mmio() if device is unplugged to prevent crash in GPU initialization failure [Why] In amdgpu_driver_load_kms, when amdgpu_device_init returns error during driver modprobe, it will start the error handle path immediately and call into amdgpu_device_unmap_mmio as well to release mapped VRAM. However, in the following release callback, driver stills visits the unmapped memory like vcn.inst[i].fw_shared_cpu_addr in vcn_v3_0_sw_fini. So a kernel crash occurs.
