2023-06-08drm/msm/dp: enable HDP plugin/unplugged interrupts at hpd_enable/disableKuogee Hsieh
The internal_hpd flag is set to true by dp_bridge_hpd_enable() and set to false by dp_bridge_hpd_disable() to handle GPIO pinmuxed into DP controller case. HDP related interrupts can not be enabled until internal_hpd is set to true. At current implementation dp_display_config_hpd() will initialize DP host controller first followed by enabling HDP related interrupts if internal_hpd was true at that time. Enable HDP related interrupts depends on internal_hpd status may leave system with DP driver host is in running state but without HDP related interrupts being enabled. This will prevent external display from being detected. Eliminated this dependency by moving HDP related interrupts enable/disable be done at dp_bridge_hpd_enable/disable() directly regardless of internal_hpd status.

2023-06-08bnxt_en: Implement .set_port / .unset_port UDP tunnel callbacksSomnath Kotur
As per the new udp tunnel framework, drivers which need to know the details of a port entry (i.e. port type) when it gets deleted should use the .set_port / .unset_port callbacks. Implementing the current .udp_tunnel_sync callback would mean that the deleted tunnel port entry would be all zeros. This used to work on older firmware because it would not check the input when deleting a tunnel port. With newer firmware, the delete will now fail and subsequent tunnel port allocation will fail as a result.

The firmware can send PHC_RTC_UPDATE async event on a PF that may not have PTP registered. In such a case, there will be a null pointer deference for bp->ptp_cfg when we try to handle the event. Fix it by not registering for this event with the firmware if !bp->ptp_cfg. Also, check that bp->ptp_cfg is valid before proceeding when we receive the event.

2023-06-08bnxt_en: Query default VLAN before VNIC setup on a VFSomnath Kotur
We need to call bnxt_hwrm_func_qcfg() on a VF to query the default VLAN that may be setup by the PF. If a default VLAN is enabled, the VF cannot support VLAN acceleration on the receive side and the VNIC must be setup to strip out the default VLAN tag. If a default VLAN is not enabled, the VF can support VLAN acceleration on the receive side. The VNIC should be set up to strip or not strip the VLAN based on the RX VLAN acceleration setting. Without this call to determine the default VLAN before calling bnxt_setup_vnic(), the VNIC may not be set up correctly. For example, bnxt_setup_vnic() may set up to strip the VLAN tag based on stale default VLAN information. If RX VLAN acceleration is not enabled, the VLAN tag will be incorrectly stripped and the RX data path will not work correctly.

Only older NIC controller's firmware uses the PROC AP reset type. Firmware on 5731X/5741X and newer chips does not support this reset type. When bnxt_reset() issues a series of resets, this PROC AP reset may actually fail on these newer chips because the firmware is not ready to accept this unsupported command yet.

2023-06-08accel/ivpu: Do not trigger extra VPU reset if the VPU is idleAndrzej Kacprowski
Turning off the PLL and entering D0i3 will reset the VPU so an explicit IP reset is redundant. But if the VPU is active, it may interfere with PLL disabling and to avoid that, we have to issue an additional IP reset to silence the VPU before turning off the PLL.

2023-06-07drm/amd: Disallow s0ix without BIOS support againMario Limonciello
commit cf488dcd0ab7 ("drm/amd: Allow s0ix without BIOS support") showed improvements to power consumption over suspend when s0ix wasn't enabled in BIOS and the system didn't support S3. This patch however was misguided because the reason the system didn't support S3 was because SMT was disabled in OEM BIOS setup. This prevented the BIOS from allowing S3. Also allowing GPUs to use the s2idle path actually causes problems if they're invoked on systems that may not support s2idle in the platform firmware. `systemd` has a tendency to try to use `s2idle` if `deep` fails for any reason, which could lead to unexpected flows. The original commit also fixed a problem during resume from suspend to idle without hardware support, but this is no longer necessary with commit ca4751866397 ("drm/amd: Don't allow s0ix on APUs older than Raven") Revert commit cf488dcd0ab7 ("drm/amd: Allow s0ix without BIOS support") to make it match the expected behavior again.

kafs incorrectly passes a zero mtime (ie. 1st Jan 1970) to the server when creating a file, dir or symlink because the mtime recorded in the afs_operation struct gets passed to the server by the marshalling routines, but the afs_mkdir(), afs_create() and afs_symlink() functions don't set it. This gets masked if a file or directory is subsequently modified. Fix this by filling in op->mtime before calling the create op.

2023-06-07ice: make writes to /dev/gnssX synchronousMichal Schmidt
The current ice driver's GNSS write implementation buffers writes and works through them asynchronously in a kthread. That's bad because: - The GNSS write_raw operation is supposed to be synchronous[1][2]. - There is no upper bound on the number of pending writes. Userspace can submit writes much faster than the driver can process, consuming unlimited amounts of kernel memory. A patch that's currently on review[3] ("[v3,net] ice: Write all GNSS buffers instead of first one") would add one more problem: - The possibility of waiting for a very long time to flush the write work when doing rmmod, softlockups. To fix these issues, simplify the implementation: Drop the buffering, the write_work, and make the writes synchronous. I tested this with gpsd and ubxtool.
