2023-06-05dt-bindings: usb: xilinx: Replace Manish by PiyushMichal Simek
Manish no longer works for AMD/Xilinx and there is also no activity from him. That's why proposing Piyush as the best candidate instead.

2023-06-05arm64: zynqmp: Set qspi tx-buswidth to 4Amit Kumar Mahapatra
All ZynqMP boards are setting up tx-buswidth to 1. Due to this the framework only issues 1-1-1 write commands to the GQSPI driver. But the GQSPI controller is capable of handling 1-4-4 write commands, so updated the tx-buswidth to 4. Using all 4 lines will increase the tx data transfer rate, as now the tx data will be transferred on four lines instead on single line.

2023-05-16arm64: zynqmp: Add linux,code for gpio buttonSrinivas Neeli
BTN_MISC looks like the most reasonable option for this button. Button is used by firmware to indicate (after reset, power up) that user wants to do firmware upgrade via firmware update utility. For bootloader or OS is this just user button which is worth to have it mapped. Also button can be used as a wakeup source and pressing it for more time can generate more chars that's why also adding wakeup-source and autorepeat properties.

2023-05-16arm64: zynqmp: Fix usb reset over bootmode pins on zcu100Michal Simek
The commit 53ba1b2bdaf7 ("arm64: dts: zynqmp: Add mode-pin GPIO controller DT node") added usb phy reset over bootmode pins by default on usb0 only. zcu100 is using usb0 as peripheral and usb1 as host. Unfortunately reset line is shared for both usb ulpi phys but usb_rst_b is connected to usb5744 hub which is used only in host mode.

Build: - Require libtraceevent to build, one can disable it using NO_LIBTRACEEVENT=1. It is required for tools like 'perf sched', 'perf kvm', 'perf trace', etc. libtraceevent is available in most distros so installing 'libtraceevent-devel' should be a one-time event to continue building perf as usual. Using NO_LIBTRACEEVENT=1 produces tooling that is functional and sufficient for lots of users not interested in those libtraceevent dependent features. - Allow Python support in 'perf script' when libtraceevent isn't linked, as not all features requires it, for instance Intel PT does not use tracepoints. - Error if the python interpreter needed for jevents to work isn't available and NO_JEVENTS=1 isn't set, preventing a build without support for JSON vendor events, which is a rare but possible condition. The two check error messages: $(error ERROR: No python interpreter needed for jevents generation. Install python or build with NO_JEVENTS=1.) $(error ERROR: Python interpreter needed for jevents generation too old (older than 3.6). Install a newer python or build with NO_JEVENTS=1.) - Make libbpf 1.0 the minimum required when building with out of tree, distro provided libbpf. - Use libsdtc++'s and LLVM's libcxx's __cxa_demangle, a portable C++ demangler, add 'perf test' entry for it. - Make binutils libraries opt in, as distros disable building with it due to licensing, they were used for C++ demangling, for instance. - Switch libpfm4 to opt-out rather than opt-in, if libpfm-devel (or equivalent) isn't installed, we'll just have a build warning: Makefile.config:1144: libpfm4 not found, disables libpfm4 support.

Fixed by reversing the order of puts so that the leader is put last. - Also several fixes were made to places where reference counts were not being held. - Make this one of the tests in 'make -C tools/perf build-test' to regularly build test it and to make sure no direct access to the reference counted structs are made, doing that via accessors to check the validity of the struct pointer.

2023-05-06dmapool: link blocks across pagesKeith Busch
The allocated dmapool pages are never freed for the lifetime of the pool. There is no need for the two level list+stack lookup for finding a free block since nothing is ever removed from the list. Just use a simple stack, reducing time complexity to constant. The implementation inserts the stack linking elements and the dma handle of the block within itself when freed. This means the smallest possible dmapool block is increased to at most 16 bytes to accommodate these fields, but there are no exisiting users requesting a dma pool smaller than that anyway. Removing the list has a significant change in performance. Using the kernel's micro-benchmarking self test: Before: # modprobe dmapool_test dmapool test: size:16 blocks:8192 time:57282 dmapool test: size:64 blocks:8192 time:172562 dmapool test: size:256 blocks:8192 time:789247 dmapool test: size:1024 blocks:2048 time:371823 dmapool test: size:4096 blocks:1024 time:362237 After: # modprobe dmapool_test dmapool test: size:16 blocks:8192 time:24997 dmapool test: size:64 blocks:8192 time:26584 dmapool test: size:256 blocks:8192 time:33542 dmapool test: size:1024 blocks:2048 time:9022 dmapool test: size:4096 blocks:1024 time:6045 The module test allocates quite a few blocks that may not accurately represent how these pools are used in real life. For a more marco level benchmark, running fio high-depth + high-batched on nvme, this patch shows submission and completion latency reduced by ~100usec each, 1% IOPs improvement, and perf record's time spent in dma_pool_alloc/free were reduced by half.
