| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The recent build changes cause perf to not compile for sparc64 since the arch/sparc64/Build file does not exist: /home/dahern/kernels/linux.git/tools/build/Makefile.build:40: arch/sparc64/Build: No such file or directory Fix by converting the sparc64 RAW_ARCH to sparc ARCH -- similar to what is done for x86_64.

This commit added 'int refcnt' to struct perf_mmap and the addition makes the event_copy element no longer 8-byte aligned. Fix by adding __attribute__((aligned(8))) to the event_copy struct member.

| * perf tools: Fix probing for PERF_FLAG_FD_CLOEXEC flagAdrian Hunter2015-02-251-3/+15
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Commit f6edb53c4993ffe92ce521fb449d1c146cea6ec2 converted the probe to a CPU wide event first (pid == -1). For kernels that do not support the PERF_FLAG_FD_CLOEXEC flag the probe fails with EINVAL. Since this errno is not handled pid is not reset to 0 and the subsequent use of pid = -1 as an argument brings in an additional failure path if perf_event_paranoid > 0: $ perf record -- sleep 1 perf_event_open(..., 0) failed unexpectedly with error 13 (Permission denied) [ perf record: Woken up 1 times to write data ] [ perf record: Captured and wrote 0.007 MB /tmp/perf.data (11 samples) ] Also, ensure the fd of the confirmation check is closed and comment why pid = -1 is used. Needs to go to 3.18 stable tree as well.

This is a compulsory feature, and we implement it here. There are some subtleties involving access widths which we should note: 4.1.4.7.1 Device Requirements: PCI configuration access capability ... Upon detecting driver write access to pci_cfg_data, the device MUST execute a write access at offset cap.offset at BAR selected by cap.bar using the first cap.length bytes from pci_cfg_data. Upon detecting driver read access to pci_cfg_data, the device MUST execute a read access of length cap.length at offset cap.offset at BAR selected by cap.bar and store the first cap.length bytes in pci_cfg_data. So, for a write, we copy into the pci_cfg_data window, then write from there out to the BAR. This works correctly if cap.length != width of write. Similarly, for a read, we read into window from the BAR then read the value from there. Signed-off-by: Rusty Russell <rusty@rustcorp.com.au>

| * | | Tools: hv: remove unused bytes_written from kvp_update_file()Vitaly Kuznetsov2015-01-251-3/+1Star
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | fwrite() does not actually return the number of bytes written and this value is being ignored anyway and ferror() is being called to check for an error. As we assign to this variable and never use it we get the following compile-time warning: hv_kvp_daemon.c:149:9: warning: variable .bytes_written. set but not used [-Wunused-but-set-variable] Remove bytes_written completely.
