2024-09-11perf trace: If a syscall arg is marked as 'const', assume it is coming ↵Arnaldo Carvalho de Melo
_from_ userspace We need to decide where to copy syscall arg contents, if at the syscalls:sys_entry hook, meaning is something that is coming from user to kernel space, or if it is a response, i.e. if it is something the _kernel_ is filling in and thus going to userspace.

2024-09-11platform/x86: asus-wmi: don't fail if platform_profile already registeredLuke D. Jones
On some newer laptops ASUS laptops SPS support is advertised but not actually used, causing the AMD driver to register as a platform_profile handler. If this happens then the asus_wmi driver would error with -EEXIST when trying to register its own handler leaving the user with a possibly unusable system. This is especially true for laptops with an MCU that emit a stream of HID packets, some of which can be misinterpreted as shutdown signals. We can safely continue loading the driver instead of bombing out. Signed-off-by: Luke D.

LTR value is a mechanism for a device to indicate tolerance to access the corresponding resource. When system suspends, the resource is not available and therefore the LTR value could be ignored.

2024-09-11RDMA/mlx5: Add handling for memory scheme page fault eventsMichael Guralnik
The memory scheme page fault event is a new approch in handling page fault on mkeys using the on-demand-paging feature. The major shift in handling the page fault in this scheme is that the HW is taking responsibilty for parsing the faulted mkey instead of the previous approach where the driver would read and parse the wqes and query the mkeys to get to the direct mkey that we need to handle. Therefore, the event we get from FW in this scheme will contain the direct mkey and address we need to handle and require much less work from driver. Additionally, to optimize performance, the FW can generate the event on a memory area that is larger than the faulted memory operation is requiring, to 'prefetch' memory that is around it and will likely be used soon. Unlike previous types of page fault, the memory page scheme fault does not always require a resume command after handling the page fault as the FW can post multiple events on same mkey and will set the 'last' flag only on the page fault that requires the resume command.

phylink The function allows for the configuration of a fixed link state for a given phylink instance. This addition is particularly useful for network devices that operate with a fixed link configuration, where the link parameters do not change dynamically. By using `phylink_set_fixed_link()`, drivers can easily set up the fixed link state during initialization or configuration changes.
