[PATCH] Revert "drm/mipi-dsi: Set the fwnode for mipi_dsi_device"

by Jason-JH.Lin via B4 Relay

From: "Jason-JH.Lin" <jason-jh.lin(a)mediatek.com> This reverts commit ac88a1f41f93499df6f50fd18ea835e6ff4f3200. Reason for revert: 1. The commit [1] does not land on linux-5.15, so this patch does not fix anything. 2. Since the fw_device improvements series [2] does not land on linux-5.15, using device_set_fwnode() causes the panel to flash during bootup. Incorrect link management may lead to incorrect device initialization, affecting firmware node links and consumer relationships. The fwnode setting of panel to the DSI device would cause a DSI initialization error without series[2], so this patch was reverted to avoid using the incomplete fw_devlink functionality.

Request to backport a fix to 6.10 and 6.11 stable kernels

by Dhananjay Ugwekar

Hello, The patch "[PATCH v3] perf/x86/rapl: Fix the energy-pkg event for AMD CPUs" fixes the RAPL energy-pkg event on AMD CPUs. It was broken by "commit 63edbaa48a57 ("x86/cpu/topology: Add support for the AMD 0x80000026 leaf")", which got merged in v6.10-rc1. I missed the "Fixes" tag while posting the patch on LKML. Please backport the fix to 6.10 (I see this is EOL so probably this wont be possible) and 6.11 stable kernels. Mainline commit ID for the fix is "8d72eba1cf8c". Thanks, Dhananjay

[PATCH v2 4/5] xhci: Don't perform Soft Retry for Etron xHCI host

by Kuangyi Chiang

Since commit f8f80be501aa ("xhci: Use soft retry to recover faster from transaction errors"), unplugging USB device while enumeration results in errors like this: [ 364.855321] xhci_hcd 0000:0b:00.0: ERROR Transfer event for disabled endpoint slot 5 ep 2 [ 364.864622] xhci_hcd 0000:0b:00.0: @0000002167656d70 67f03000 00000021 0c000000 05038001 [ 374.934793] xhci_hcd 0000:0b:00.0: Abort failed to stop command ring: -110 [ 374.958793] xhci_hcd 0000:0b:00.0: xHCI host controller not responding, assume dead [ 374.967590] xhci_hcd 0000:0b:00.0: HC died; cleaning up [ 374.973984] xhci_hcd 0000:0b:00.0: Timeout while waiting for configure endpoint command Seems that Etorn xHCI host can not perform Soft Retry correctly, apply XHCI_NO_SOFT_RETRY quirk to disable Soft Retry and then issue is gone.

[PATCH v2 3/5] xhci: Fix control transfer error on Etron xHCI host

by Kuangyi Chiang

Performing a stability stress test on a USB3.0 2.5G ethernet adapter results in errors like this: [ 91.441469] r8152 2-3:1.0 eth3: get_registers -71 [ 91.458659] r8152 2-3:1.0 eth3: get_registers -71 [ 91.475911] r8152 2-3:1.0 eth3: get_registers -71 [ 91.493203] r8152 2-3:1.0 eth3: get_registers -71 [ 91.510421] r8152 2-3:1.0 eth3: get_registers -71 The r8152 driver will periodically issue lots of control-IN requests to access the status of ethernet adapter hardware registers during the test. This happens when the xHCI driver enqueue a control TD (which cross over the Link TRB between two ring segments, as shown) in the endpoint zero's transfer ring. Seems the Etron xHCI host can not perform this TD correctly, causing the USB transfer error occurred, maybe the upper driver retry that control-IN request can solve problem, but not all drivers do this. | | ------- | TRB | Setup Stage ------- | TRB | Link ------- ------- | TRB | Data Stage ------- | TRB | Status Stage ------- | | To work around this, the xHCI driver should enqueue a No Op TRB if next available TRB is the Link TRB in the ring segment, this can prevent the Setup and Data Stage TRB to be breaked by the Link TRB. Check if the XHCI_ETRON_HOST quirk flag is set before invoking the workaround in xhci_queue_ctrl_tx(). Fixes: d0e96f5a71a0 ("USB: xhci: Control transfer support.")

On DCN401, the vblank interrupts never stop coming, and hence we never get a chance to trigger idle optimizations. Add a workaround to enable immediate disable only on APUs for now. This adds a 2-frame delay for triggering idle optimization, which is a negligible overhead.
