net: libwx: use request_irq for VF misc interrupt

2026-05-14T13:31:09+00:00

commit 7a33345153eeeda195c55f15be27074e4c3b5109 upstream. Currently, request_threaded_irq() is used with a primary handler but a NULL threaded handler, while also setting the IRQF_ONESHOT flag. This specific combination triggers a WARNING since the commit aef30c8d569c ("genirq: Warn about using IRQF_ONESHOT without a threaded handler"). WARNING: kernel/irq/manage.c:1502 at __setup_irq+0x4fa/0x760 Fix the issue by switching to request_irq(), which is the appropriate interface or a non-threaded interrupt handler, and removing the unnecessary IRQF_ONESHOT flag.

net: libwx: fix VF illegal register access

2026-05-14T13:31:09+00:00

commit 694de316f607fe2473d52ca0707e3918e72c1562 upstream. Register WX_CFG_PORT_ST is a PF restricted register. When a VF is initialized, attempting to read this register triggers an illegal register access, which lead to a system hang. When the device is VF, the bus function ID can be obtained directly from the PCI_FUNC(pdev->devfn).

Convert 'alloc_flex' family to use the new default GFP_KERNEL argument

2026-02-22T01:09:51+00:00

This is the exact same thing as the 'alloc_obj()' version, only much smaller because there are a lot fewer users of the *alloc_flex() interface. As with alloc_obj() version, this was done entirely with mindless brute force, using the same script, except using 'flex' in the pattern rather than 'objs*'. Signed-off-by: Linus Torvalds

treewide: Replace kmalloc with kmalloc_obj for non-scalar types

2026-02-21T09:02:28+00:00

This is the result of running the Coccinelle script from scripts/coccinelle/api/kmalloc_objs.cocci. The script is designed to avoid scalar types (which need careful case-by-case checking), and instead replace kmalloc-family calls that allocate struct or union object instances: Single allocations: kmalloc(sizeof(TYPE), ...) are replaced with: kmalloc_obj(TYPE, ...) Array allocations: kmalloc_array(COUNT, sizeof(TYPE), ...) are replaced with: kmalloc_objs(TYPE, COUNT, ...) Flex array allocations: kmalloc(struct_size(PTR, FAM, COUNT), ...) are replaced with: kmalloc_flex(*PTR, FAM, COUNT, ...) (where TYPE may also be *VAR) The resulting allocations no longer return "void *", instead returning "TYPE *". Signed-off-by: Kees Cook

net: libwx: remove unused rx_buffer_pgcnt

net: txgbe: improve functions of AML 40G devices

2025-11-20T11:47:26+00:00

Support to identify QSFP modules for AML 40G devices. The definition of GPIO pins follows the design of the QSFP modules, and TXGBE_GPIOBIT_4 is used for module present. Meanwhile, implement phylink in XLGMII mode by default, and get the link state from MAC link.

net: txgbe: rename the SFP related

2025-11-20T11:47:26+00:00

QSFP supported will be introduced for AML 40G devices, the code related to identify various modules should be renamed to more appropriate names. And struct txgbe_hic_i2c_read used to get module information is renamed as struct txgbe_hic_get_module_info, because another SW-FW command to read I2C will be added later.
