2024-08-14spi: spi-cadence-quadspi: Fix OSPI NOR failures during system resumeVignesh Raghavendra
Its necessary to call pm_runtime_force_*() hooks as part of system suspend/resume calls so that the runtime_pm hooks get called. This ensures latest state of the IP is cached and restored during system sleep. This is especially true if runtime autosuspend is enabled as runtime suspend hooks may not be called at all before system sleeps. Without this patch, OSPI NOR enumeration (READ_ID) fails during resume as context saved during suspend path is inconsistent.

2024-08-14Revert "ata: libata-scsi: Honor the D_SENSE bit for CK_COND=1 and no error"Niklas Cassel
This reverts commit 28ab9769117ca944cb6eb537af5599aa436287a4. Sense data can be in either fixed format or descriptor format. SAT-6 revision 1, "10.4.6 Control mode page", defines the D_SENSE bit: "The SATL shall support this bit as defined in SPC-5 with the following exception: if the D_ SENSE bit is set to zero (i.e., fixed format sense data), then the SATL should return fixed format sense data for ATA PASS-THROUGH commands." The libata SATL has always kept D_SENSE set to zero by default. (It is however possible to change the value using a MODE SELECT SG_IO command.) Failed ATA PASS-THROUGH commands correctly respected the D_SENSE bit, however, successful ATA PASS-THROUGH commands incorrectly returned the sense data in descriptor format (regardless of the D_SENSE bit). Commit 28ab9769117c ("ata: libata-scsi: Honor the D_SENSE bit for CK_COND=1 and no error") fixed this bug for successful ATA PASS-THROUGH commands. However, after commit 28ab9769117c ("ata: libata-scsi: Honor the D_SENSE bit for CK_COND=1 and no error"), there were bug reports that hdparm, hddtemp, and udisks were no longer working as expected. These applications incorrectly assume the returned sense data is in descriptor format, without even looking at the RESPONSE CODE field in the returned sense data (to see which format the returned sense data is in). Considering that there will be broken versions of these applications around roughly forever, we are stuck with being bug compatible with older kernels.

Commit a0821ca14bb8 ("media: atomisp: Remove test pattern generator (TPG) support") broke BYT support because it removed a seemingly unused field from struct sh_css_sp_config and a seemingly unused value from enum ia_css_input_mode. But these are part of the ABI between the kernel and firmware on ISP2400 and this part of the TPG support removal changes broke ISP2400 support. ISP2401 support was not affected because on ISP2401 only a part of struct sh_css_sp_config is used. Restore the removed field and enum value to fix this.

'struct config_item_type' is not modified in this driver. This structure is only used with config_group_init_type_name() which takes a const struct config_item_type* as a 3rd argument.

2024-08-13iavf: add support for offloading tc U32 cls filtersAhmed Zaki
Add support for offloading cls U32 filters. Only "skbedit queue_mapping" and "drop" actions are supported. Also, only "ip" and "802_3" tc protocols are allowed. The PF must advertise the VIRTCHNL_VF_OFFLOAD_TC_U32 capability flag. Since the filters will be enabled via the FD stage at the PF, a new type of FDIR filters is added and the existing list and state machine are used. The new filters can be used to configure flow directors based on raw (binary) pattern in the rx packet. Examples: 0. # tc qdisc add dev enp175s0v0 ingress 1. Redirect UDP from src IP 192.168.2.1 to queue 12: # tc filter add dev <dev> protocol ip ingress u32 \ match u32 0x45000000 0xff000000 at 0 \ match u32 0x00110000 0x00ff0000 at 8 \ match u32 0xC0A80201 0xffffffff at 12 \ match u32 0x00000000 0x00000000 at 24 \ action skbedit queue_mapping 12 skip_sw 2. Drop all ICMP: # tc filter add dev <dev> protocol ip ingress u32 \ match u32 0x45000000 0xff000000 at 0 \ match u32 0x00010000 0x00ff0000 at 8 \ match u32 0x00000000 0x00000000 at 24 \ action drop skip_sw 3. Redirect ICMP traffic from MAC 3c:fd:fe:a5:47:e0 to queue 7 (note proto: 802_3): # tc filter add dev <dev> protocol 802_3 ingress u32 \ match u32 0x00003CFD 0x0000ffff at 4 \ match u32 0xFEA547E0 0xffffffff at 8 \ match u32 0x08004500 0xffffff00 at 12 \ match u32 0x00000001 0x000000ff at 20 \ match u32 0x0000 0x0000 at 40 \ action skbedit queue_mapping 7 skip_sw Notes on matches: 1 - All intermediate fields that are needed to parse the correct PTYPE must be provided (in e.g. 3: Ethernet Type 0x0800 in MAC, IP version and IP length: 0x45 and protocol: 0x01 (ICMP)). 2 - The last match must provide an offset that guarantees all required headers are accounted for, even if the last header is not matched. For example, in #2, the last match is 4 bytes at offset 24 starting from IP header, so the total is 14 (MAC) + 24 + 4 = 42, which is the sum of MAC+IP+ICMP headers.

2024-08-13iavf: refactor add/del FDIR filtersAhmed Zaki
In preparation for a second type of FDIR filters that can be added by tc-u32, move the add/del of the FDIR logic to be entirely contained in iavf_fdir.c. The iavf_find_fdir_fltr_by_loc() is renamed to iavf_find_fdir_fltr() to be more agnostic to the filter ID parameter (for now @loc, which is relevant only to current FDIR filters added via ethtool). The FDIR filter deletion is moved from iavf_del_fdir_ethtool() in ethtool.c to iavf_fdir_del_fltr(). While at it, fix a minor bug where the "fltr" is accessed out of the fdir_fltr_lock spinlock protection.

2024-08-13drm/msm: fix the highest_bank_bit for sc7180Abhinav Kumar
sc7180 programs the ubwc settings as 0x1e as that would mean a highest bank bit of 14 which matches what the GPU sets as well. However, the highest_bank_bit field of the msm_mdss_data which is being used to program the SSPP's fetch configuration is programmed to a highest bank bit of 16 as 0x3 translates to 16 and not 14. Fix the highest bank bit field used for the SSPP to match the mdss and gpu settings.

2024-08-13dm persistent data: fix memory allocation failureMikulas Patocka
kmalloc is unreliable when allocating more than 8 pages of memory. It may fail when there is plenty of free memory but the memory is fragmented. Zdenek Kabelac observed such failure in his tests. This commit changes kmalloc to kvmalloc - kvmalloc will fall back to vmalloc if the large allocation fails.

2024-08-13thermal: sysfs: Get to trips via attribute pointersRafael J. Wysocki
The _store() and _show() functions for sysfs attributes corresponding to trip point parameters (type, temperature and hysteresis) read the trip ID from the attribute name and then use the trip ID as the index in the given thermal zone's trips table to get to the trip object they want. Instead of doing this, make them use the attribute pointer they get as the second argument to get to the trip object embedded in the same struct thermal_trip_desc as the struct device_attribute pointed to by it, which is much more straightforward and less overhead.
