misc: microchip: pci1xxxx: Resolve return code mismatch during GPIO set config

2025-01-17T12:40:53Z

commit c7a5378a0f707686de3ddb489f1653c523bb7dcc upstream. Driver returns -EOPNOTSUPPORTED on unsupported parameters case in set config. Upper level driver checks for -ENOTSUPP. Because of the return code mismatch, the ioctls from userspace fail. Resolve the issue by passing -ENOTSUPP during unsupported case.

misc: microchip: pci1xxxx: Resolve kernel panic during GPIO IRQ handling

2025-01-17T12:40:53Z

commit 194f9f94a5169547d682e9bbcc5ae6d18a564735 upstream. Resolve kernel panic caused by improper handling of IRQs while accessing GPIO values. This is done by replacing generic_handle_irq with handle_nested_irq. Fixes: 1f4d8ae231f4 ("misc: microchip: pci1xxxx: Add gpio irq handler and irq helper functions irq_ack, irq_mask, irq_unmask and irq_set_type of irq_chip.")

misc: eeprom: eeprom_93cx6: Add quirk for extra read clock cycle

2024-12-14T19:04:09Z

[ Upstream commit 7738a7ab9d12c5371ed97114ee2132d4512e9fd5 ] Add a quirk similar to eeprom_93xx46 to add an extra clock cycle before reading data from the EEPROM. The 93Cx6 family of EEPROMs output a "dummy 0 bit" between the writing of the op-code/address from the host to the EEPROM and the reading of the actual data from the EEPROM. More info can be found on page 6 of the AT93C46 datasheet (linked below). Similar notes are found in other 93xx6 datasheets. In summary the read operation for a 93Cx6 EEPROM is: Write to EEPROM: 110[A5-A0] (9 bits) Read from EEPROM: 0[D15-D0] (17 bits) Where: 110 is the start bit and READ OpCode [A5-A0] is the address to read from 0 is a "dummy bit" preceding the actual data [D15-D0] is the actual data. Looking at the READ timing diagrams in the 93Cx6 datasheets the dummy bit should be clocked out on the last address bit clock cycle meaning it should be discarded naturally. However, depending on the hardware configuration sometimes this dummy bit is not discarded. This is the case with Exar PCI UARTs which require an extra clock cycle between sending the address and reading the data.

Compiler Attributes: disable __counted_by for clang < 19.1.3

2024-12-05T13:02:45Z

commit f06e108a3dc53c0f5234d18de0bd224753db5019 upstream. This patch disables __counted_by for clang versions < 19.1.3 because of the two issues listed below. It does this by introducing CONFIG_CC_HAS_COUNTED_BY. 1. clang < 19.1.2 has a bug that can lead to __bdos returning 0: https://github.com/llvm/llvm-project/pull/110497 2. clang < 19.1.3 has a bug that can lead to __bdos being off by 4: https://github.com/llvm/llvm-project/pull/112636 Fixes: c8248faf3ca2 ("Compiler Attributes: counted_by: Adjust name and identifier expansion") Cc: stable@vger.kernel.org # 6.6.x: 16c31dd7fdf6: Compiler Attributes: counted_by: bump min gcc version Cc: stable@vger.kernel.org # 6.6.x: 2993eb7a8d34: Compiler Attributes: counted_by: fixup clang URL Cc: stable@vger.kernel.org # 6.6.x: 231dc3f0c936: lkdtm/bugs: Improve warning message for compilers without counted_by support Cc: stable@vger.kernel.org # 6.6.x Reported-by: Nathan Chancellor Closes: https://lore.kernel.org/all/20240913164630.GA4091534@thelio-3990X/ Reported-by: kernel test robot Closes: https://lore.kernel.org/oe-lkp/202409260949.a1254989-oliver.sang@intel.com Link: https://lore.kernel.org/all/Zw8iawAF5W2uzGuh@archlinux/T/#m204c09f63c076586a02d194b87dffc7e81b8de7b Suggested-by: Nathan Chancellor Signed-off-by: Jan Hendrik Farr Reviewed-by: Nathan Chancellor Tested-by: Nathan Chancellor Reviewed-by: Miguel Ojeda Reviewed-by: Thorsten Blum Link: https://lore.kernel.org/r/20241029140036.577804-2-kernel@jfarr.cc Signed-off-by: Kees Cook Signed-off-by: Greg Kroah-Hartman

mei: use kvmalloc for read buffer

2024-10-29T03:01:40Z

Read buffer is allocated according to max message size, reported by the firmware and may reach 64K in systems with pxp client. Contiguous 64k allocation may fail under memory pressure. Read buffer is used as in-driver message storage and not required to be contiguous. Use kvmalloc to allow kernel to allocate non-contiguous memory.
