2021-09-16drm/amd/display: Fix white screen page fault for gpuvmNicholas Kazlauskas
[Why] The "base_addr_is_mc_addr" field was added for dcn3.1 support but pa_config was never updated to set it to false. Uninitialized memory causes it to be set to true which results in address mistranslation and white screen. [How] Use memset to ensure all fields are initialized to 0 by default.

2021-09-16amd/display: enable panel orientation quirksSimon Ser
This patch allows panel orientation quirks from DRM core to be used. They attach a DRM connector property "panel orientation" which indicates in which direction the panel has been mounted. Some machines have the internal screen mounted with a rotation. Since the panel orientation quirks need the native mode from the EDID, check for it in amdgpu_dm_connector_ddc_get_modes.

2021-09-16drm/amd/pm: fix runpm hang when amdgpu loaded prior to sound driverEvan Quan
Current RUNPM mechanism relies on PMFW to master the timing for BACO in/exit. And that needs cooperation from sound driver for dstate change notification for function 1(audio). Otherwise(on sound driver missing), BACO cannot be kicked in correctly and hang will be observed on RUNPM exit.

2021-09-16drm/amd/display: Get backlight from PWM if DMCU is not initializedHarry Wentland
On Carrizo/Stoney systems we set backlight through panel_cntl, i.e. directly via the PWM registers, if DMCU is not initialized. We always read it back through ABM registers which leads to a mismatch and forces atomic_commit to program the backlight each time. Instead make sure we use the same logic for backlight readback, i.e. read it from panel_cntl if DMCU is not initialized. We also need to remove some extraneous and incorrect calculations at the end of dce_get_16_bit_backlight_from_pwm.

2021-09-16mlxbf_gige: clear valid_polarity upon openDavid Thompson
The network interface managed by the mlxbf_gige driver can get into a problem state where traffic does not flow. In this state, the interface will be up and enabled, but will stop processing received packets. This problem state will happen if three specific conditions occur: 1) driver has received more than (N * RxRingSize) packets but less than (N+1 * RxRingSize) packets, where N is an odd number Note: the command "ethtool -g <interface>" will display the current receive ring size, which currently defaults to 128 2) the driver's interface was disabled via "ifconfig oob_net0 down" during the window described in #1. 3) the driver's interface is re-enabled via "ifconfig oob_net0 up" This patch ensures that the driver's "valid_polarity" field is cleared during the open() method so that it always matches the receive polarity used by hardware. Without this fix, the driver needs to be unloaded and reloaded to correct this problem state.

Paket Size: 64904 This is what you see on igb, the code igc has been taken from. However, on igc the output is Max. Paket Size: 1516 so the GSO aggregate packets are segmented by the kernel before calling igc_xmit_frame. Inside the subsequent call to igc_tso, the check for skb_is_gso(skb) fails and the function returns prematurely. It turns out that this occurs because the feature flags aren't set entirely correctly in igc_probe. In contrast to the original code from igb_probe, igc_probe neglects to set the flags required to allow tunnel offloading. Setting the same flags as igb fixes the issue on igc.

Invoke release_firmware() when the firmware fails to boot in sof_probe_continue(). The request_firmware() framework must be informed of failures in sof_probe_continue() otherwise its internal "batching" feature (different from caching) cached the firmware image forever. Attempts to correct the file in /lib/firmware/ were then silently and confusingly ignored until the next reboot. Unloading the drivers did not help because from their disconnected perspective the firmware had failed so there was nothing to release. Also leverage the new snd_sof_fw_unload() function to simplify the snd_sof_device_remove() function.

2021-09-16drm/etnaviv: add missing MMU context put when reaping MMU mappingLucas Stach
When we forcefully evict a mapping from the the address space and thus the MMU context, the MMU context is leaked, as the mapping no longer points to it, so it doesn't get freed when the GEM object is destroyed. Add the mssing context put to fix the leak.

2021-09-16drm/etnaviv: keep MMU context across runtime suspend/resumeLucas Stach
The MMU state may be kept across a runtime suspend/resume cycle, as we avoid a full hardware reset to keep the latency of the runtime PM small. Don't pretend that the MMU state is lost in driver state. The MMU context is pushed out when new HW jobs with a different context are coming in. The only exception to this is when the GPU is unbound, in which case we need to make sure to also free the last active context.
