treewide: refresh kmalloc_obj() conversions

2026-09-05T04:37:00+00:00

This is another run of the Coccinelle script for converting kmalloc() family of allocations to kmalloc_obj() via the existing rules in scripts/coccinelle/api/kmalloc_objs.cocci This catches both the set of kmalloc() uses added since the first kmalloc_obj() conversions in v7.0 and adds a large group missed in the first pass due to Coccinelle not interacting well with the cleanup.h scoped_...() family of macros[1]. I worked around this with spatch's "--macro-file" argument to a file with all the scoped_...() macros mapped to Coccinelle's YACFE_ITERATOR[2] as that was the closest viable control flow indicator I could find. Build tested allmodconfig on x86, arm64, arm, loongarch, mips, powerpc, riscv, and s390 with no new warnings.

pds_core: don't release PCI regions for VFs on reset

2026-09-05T01:07:36+00:00

pdsc_reset_prepare() called pci_release_regions() unconditionally, but only PFs call pci_request_regions() (pdsc_init_pf). On a VF FLR this makes the kernel warn "Trying to free nonexistent resource".

pds_core: fix cmd_regs access racing BAR unmap on reset

2026-09-05T01:07:36+00:00

pdsc_reset_prepare() and pdsc_reset_done()'s pdsc_map_bars() error path clear/iounmap cmd_regs without devcmd_lock, and pdsc_legacy_firmware_update()'s download loop derefs cmd_regs after dropping and retaking the lock without re-checking. An FLR concurrent with a devlink flash can unmap cmd_regs under an in-flight devcmd, causing a NULL deref or a write to unmapped MMIO. Take devcmd_lock across the BAR unmap/remap, and re-check cmd_regs in the download loop. Only the PF maps cmd_regs and runs devcmd, so skip the unmap on a VF, as pdsc_remove() and pdsc_reset_done() already do. A reset that completes entirely within the unlocked window is not a correctness problem for the image: the device clears its update session, so a resumed download is rejected, and it verifies the staged image before writing a flash slot, reporting PDS_RC_BAD_FW rather than activating it. pdsc_unmap_bars() also clears info_regs, intr_status and intr_ctrl. The interrupt and start/stop readers of those are quiesced before the unmap by pdsc_fw_down(), which frees the interrupts and tears down the queues. The debugfs readers are not, since those files outlive a reset; that is pre-existing and out of scope here.

net: amd-xgbe: discard rx packets with bad FCS

2026-08-30T21:17:19+00:00

amd-xgbe driver currently sets the MAC_RCR.DCRCC bit whenever RX is enabled. This disables hardware FCS validation, causing packets with bad FCS to be accepted unconditionally. This change unsets DCRCC so that packets with bad FCS will be dropped, in-line with typical behaviours of many other network controllers. Tests: - Verified that packets with bad FCS are now dropped. - Verified that receiving packets with bad FCS will increment the `rx_crc_errors` counter.

pds_core: add host backed memory support for firmware

2026-08-06T00:59:29+00:00

Some newer AMD/Pensando cards have minimal memory and there are cases where components, specifically in the control plane, need more memory. This series adds support for host backed DMA memory that can be used by the firmware for the previously mentioned cases. Host memory allocation is best-effort: if some allocations fail, the driver continues with whatever succeeded. Firmware gracefully degrades when less memory is available than requested.

pds_core: add PLDM component info display

2026-08-06T00:59:29+00:00

Add detailed component information display via devlink info. This allows users to see individual firmware components and their versions. Components are reported as fixed, running, or stored based on their firmware-provided flags. Example output: $ devlink dev info pci/0000:00:05.0 versions: fixed: asic.id 0x0 asic.rev 0x0 running: fw.bootloader 1.2.3 fw.uboot 1.60.0-73 fw 1.60.0-73 fw.cpld 3.18 stored: fw.bootloader 1.2.3 fw.uboot 1.60.0-73 fw.uboot.gold 1.50.0-22 fw.gold 1.50.0-22 fw 1.60.0-73 fw.cpld 3.18 Signed-off-by: Brett Creeley Link: https://patch.msgid.link/20260730-upstream_v8-v12-4-136cd174ee85@amd.com Signed-off-by: Jakub Kicinski

pds_core: add PLDM firmware update support via devlink flash

2026-08-06T00:59:29+00:00

Implement PLDM FW Update in the pds_core driver using the upstream pldmfw API. This allows updating an entire PLDM FW package at once or updating specific firmware components by name. Flash the entire image: devlink dev flash pci/0000:b5:00.0 file firmware.pldmfw Flash a specific component from the PLDM FW package: devlink dev flash pci/0000:b5:00.0 \ file firmware.pldmfw component fw.cpld Per-component update uses driver-defined component names (fw, fw.cpld, etc.). Not all components support per-component update - devlink will reject the request if the specified component cannot be updated. Signed-off-by: Brett Creeley Signed-off-by: Nikhil P.
