[PATCH 0/4] soc: qcom: ice: fix dev reference leaked through of_qcom_ice_get

by Tudor Ambarus

Hi! I was recently pointed to this driver for an example on how consumers can get a pointer to the supplier's driver data and I noticed a leak. Callers of of_qcom_ice_get() leak the device reference taken by of_find_device_by_node(). Introduce devm variant for of_qcom_ice_get() to spare consumers of an extra call to put the dev reference. This set touches mmc and scsi subsystems. Since the fix is trivial for them, I'd suggest taking everything through the SoC tree with Acked-by tags if people consider this useful. Thanks!

Each commit message is retained for reference. 1) Allow a GGTT mapped batch to be submitted to user exec queue For a OA use case, one of the HW registers needs to be modified by submitting an MI_LOAD_REGISTER_IMM command to the users exec queue, so that the register is modified in the user's hardware context. In order to do this a batch that is mapped in GGTT, needs to be submitted to the user exec queue. Since all user submissions use q->vm and hence PPGTT, add some plumbing to enable submission of batches mapped in GGTT. v2: ggtt is zero-initialized, so no need to set it false (Matt Brost) 2) xe/oa: Use MI_LOAD_REGISTER_IMMEDIATE to enable OAR/OAC To enable OAR/OAC, a bit in RING_CONTEXT_CONTROL needs to be set. Setting this bit cause the context image size to change and if not done correct, can cause undesired hangs. Current code uses a separate exec_queue to modify this bit and is error-prone. As per HW recommendation, submit MI_LOAD_REGISTER_IMM to the target hardware context to modify the relevant bit. In v2 version, an attempt to submit everything to the user-queue was made, but it failed the unprivileged-single-ctx-counters test. It appears that the OACTXCONTROL must be modified from a remote context. In v3 version, all context specific register configurations were moved to use LOAD_REGISTER_IMMEDIATE and that seems to work well. This is a cleaner way, since we can now submit all configuration to user exec_queue and the fence handling is simplified. v2: (Matt) - set job->ggtt to true if create job is successful - unlock vm on job error (Ashutosh) - don't wait on job submission - use kernel exec queue where possible v3: (Ashutosh) - Fix checkpatch issues - Remove extra spaces/new-lines - Add Fixes: and Cc: tags - Reset context control bit when OA stream is closed - Submit all config via MI_LOAD_REGISTER_IMMEDIATE (Umesh) - Update commit message for v3 experiment - Squash patches for easier port to stable v4: (Ashutosh) - No need to pass q to xe_oa_submit_bb - Do not support exec queues with width > 1 - Fix disabling of CTX_CTRL_OAC_CONTEXT_ENABLE v5: (Ashutosh) - Drop reg_lri related comments - Use XE_OA_SUBMIT_NO_DEPS in xe_oa_load_with_lri Fixes: 8135f1c09dd2 ("drm/xe/oa: Don't reset OAC_CONTEXT_ENABLE on OA stream close") Signed-off-by: Umesh Nerlige Ramappa <umesh.nerlige.ramappa(a)intel.com> Reviewed-by: Matthew Brost <matthew.brost(a)intel.com> # commit 1 Reviewed-by: Ashutosh Dixit <ashutosh.dixit(a)intel.com> Cc: stable(a)vger.kernel.org Reviewed-by: Jonathan Cavitt <jonathan.cavitt(a)intel.com> Signed-off-by: Ashutosh Dixit <ashutosh.dixit(a)intel.com> Link: https://patchwork.freedesktop.org/patch/msgid/20241220171919.571528-2-umesh… (cherry picked from commit 55039832f98c7e05f1cf9e0d8c12b2490abd0f16) Signed-off-by: Thomas Hellström <thomas.hellstrom(a)linux.intel.com> diff --git a/drivers/gpu/drm/xe/xe_oa.c b/drivers/gpu/drm/xe/xe_oa.c index 8dd55798ab31..5cc0f6f9bc11 100644 --- a/drivers/gpu/drm/xe/xe_oa.c +++ b/drivers/gpu/drm/xe/xe_oa.c @@ -74,12 +74,6 @@ struct xe_oa_config { struct rcu_head rcu;

[PATCH v1] usb: typec: tcpci: Prevent Sink disconnection before vPpsShutdown in SPR PPS

by Kyle Tso

The Source can drop its output voltage to the minimum of the requested PPS APDO voltage range when it is in Current Limit Mode. If this voltage falls within the range of vPpsShutdown, the Source initiates a Hard Reset and discharges Vbus. However, currently the Sink may disconnect before the voltage reaches vPpsShutdown, leading to unexpected behavior. Prevent premature disconnection by setting the Sink's disconnect threshold to the minimum vPpsShutdown value. Additionally, consider the voltage drop due to IR drop when calculating the appropriate threshold. This ensures a robust and reliable interaction between the Source and Sink during SPR PPS Current Limit Mode operation.

[REGRESSION] Distorted sound on Acer Aspire A115-31 laptop

by Evgeny Kapun

I am using an Acer Aspire A115-31 laptop. When running newer kernel versions, sound played through headphones is distorted, but when running older versions, it is not. Kernel version: Linux version 6.12.5 (user@hostname) (gcc (Debian 14.2.0-8) 14.2.0, GNU ld (GNU Binutils for Debian) 2.43.50.20241210) #1 SMP PREEMPT_DYNAMIC Sun Dec 15 05:09:16 IST 2024 Operating System: Debian GNU/Linux trixie/sid No special actions are needed to reproduce the issue. The sound is distorted all the time, and it doesn't depend on anything besides using an affected kernel version. It seems to be caused by commit 34ab5bbc6e82214d7f7393eba26d164b303ebb4e (ALSA: hda/realtek - Add Headset Mic supported Acer NB platform). Indeed, if I remove the entry that this commit adds, the issue disappears. lspci output for the device in question: 00:0e.0 Multimedia audio controller [0401]: Intel Corporation Celeron/Pentium Silver Processor High Definition Audio [8086:3198] (rev 06) Subsystem: Acer Incorporated [ALI] Device [1025:1360] Flags: bus master, fast devsel, latency 0, IRQ 130 Memory at a1214000 (64-bit, non-prefetchable) [size=16K] Memory at a1000000 (64-bit, non-prefetchable) [size=1M] Capabilities: [50] Power Management version 3 Capabilities: [80] Vendor Specific Information: Len=14 <?> Capabilities: [60] MSI: Enable+ Count=1/1 Maskable- 64bit+ Capabilities: [70] Express Root Complex Integrated Endpoint, IntMsgNum 0 Kernel driver in use: snd_hda_intel Kernel modules: snd_hda_intel, snd_soc_avs, snd_sof_pci_intel_apl

On our board, the 002:00:07.0 bridge is misconfigured by the bootloader. Both its secondary and subordinate bus numbers are initialized to 0, while its fixed secondary bus number is set to 8. However, bus number 8 is also assigned to another bridge (0002:00:0f.0). Although this is a bootloader issue, before the change in commit 7246a4520b4b, the PCI_REASSIGN_ALL_BUS flag was set by default when PCI_PROBE_ONLY was enabled, ensuing that all the bus number for these bridges were reassigned, avoiding any conflicts. After the change introduced in commit 7246a4520b4b, the bus numbers assigned by the bootloader are reused by all other bridges, except the misconfigured 002:00:07.0 bridge. The kernel attempt to reconfigure 002:00:07.0 by reusing the fixed secondary bus number 8 assigned by bootloader. However, since a pci_bus has already been allocated for bus 8 due to the probe of 0002:00:0f.0, no new pci_bus allocated for 002:00:07.0. This results in a pci bridge device without a pci_bus attached (pdev->subordinate == NULL). Consequently, accessing pdev->subordinate in of_pci_prop_bus_range() leads to a NULL pointer dereference. To summarize, we need to restore the PCI_REASSIGN_ALL_BUS flag when PCI_PROBE_ONLY is enabled in order to work around issue like the one described above.
