The symsrc__init() overwrites dso->symtab_type as symsrc->type in dso__load_sym(). But for compressed kernel modules in the build-id cache, it should have original symtab type to be decompressed as needed. This fixes perf annotate to show disassembly of the function properly. Signed-off-by:

The commit 6ebd2547 ("perf annotate: Fix a bug following symbolic link of a build-id file") changed to use dirname to follow the symlink. But it only considers new-style build-id cache names so old names fail on readlink() and force to use system path which might not available. Signed-off-by:

So far the whole stack was thrown away when any error occurred before the maximum stack depth was unwound. This is actually a very common scenario though. The stacks that got unwound so far are still interesting. This removes a large chunk of differences when comparing perf script output for libunwind and libdw perf unwinding.

The following tests are failing on powerpc: # perf test break 18: Breakpoint overflow signal handler : FAILED! 19: Breakpoint overflow sampling : FAILED! The powerpc kenel so far does not have support to even create instruction breakpoints using the perf event interface, so those tests fail early in the config phase. I added a '->is_supported()' callback to test struct to be able to disable specific tests. It seems better than putting ifdefs directly to the test array. Signed-off-by:

The decompress_kmodule() decompresses kernel modules in order to load symbols from it. In the DSO_BINARY_TYPE__BUILD_ID_CACHE case, it needs the full file path to extract the file extension to determine the decompression method. But overwriting 'name' will fail the decompression since it might point to a non-existing old file. Instead, use dso->long_name for having the correct extension and use the real filename to decompress. In the DSO_BINARY_TYPE__SYSTEM_PATH_KMODULE_COMP case, both names should be the same. This allows resolving symbols in the old modules. Before: $ perf report -i perf.data.old | grep scsi_mod 0.00% cc1 [scsi_mod] [k] 0x0000000000004aa6 0.00% as [scsi_mod] [k] 0x00000000000099e1 0.00% cc1 [scsi_mod] [k] 0x0000000000009830 0.00% cc1 [scsi_mod] [k] 0x0000000000001b8f After: 0.00% cc1 [scsi_mod] [k] scsi_handle_queue_ramp_up 0.00% as [scsi_mod] [k] scsi_sg_alloc 0.00% cc1 [scsi_mod] [k] scsi_setup_cmnd 0.00% cc1 [scsi_mod] [k] scsi_get_command Signed-off-by: -

Like machine__findnew_module_dso(), it should set necessary info for kernel modules to find symbol info from the file. Factor out dso__set_module_info() to do it. This is needed for dso__needs_decompress() to detect such DSOs. Signed-off-by:

When perf processes build-id event, it creates DSOs with the build-id. But it didn't set the module short name (like '[module-name]') so when processing a kernel mmap event of the module, it cannot found the DSO as it only checks the short names. That leads for perf to create a same DSO without the build-id info and it'll lookup the system path even if the DSO is already in the build-id cache. After kernel was updated, perf cannot find the DSO and cannot show symbols in it anymore. You can see this if you have an old data file (w/ old kernel version): $ perf report -i perf.data.old -v |& grep scsi_mod build id event received for /lib/modules/3.19.2-1-ARCH/kernel/drivers/scsi/scsi_mod.ko.gz : cafe1ce6ca13a98a5d9ed3425cde249e57a27fc1 Failed to open /lib/modules/3.19.2-1-ARCH/kernel/drivers/scsi/scsi_mod.ko.gz, continuing without symbols ... The second message didn't show the build-id. With this patch: $ perf report -i perf.data.old -v |& grep scsi_mod build id event received for /lib/modules/3.19.2-1-ARCH/kernel/drivers/scsi/scsi_mod.ko.gz: cafe1ce6ca13a98a5d9ed3425cde249e57a27fc1 /lib/modules/3.19.2-1-ARCH/kernel/drivers/scsi/scsi_mod.ko.gz with build id cafe1ce6ca13a98a5d9ed3425cde249e57a27fc1 not found, continuing without symbols ... Now it shows the build-id but still cannot load the symbol table. This is a different problem which will be fixed in the next patch. Signed-off-by:

As reported by Patrice, the header layout of the decompressor is incorrect when building for v7-M. In this case, the __nop macro resolves to 'mov r0, r0', which is emitted as a narrow encoding, resulting in the header data fields to end up at lower offsets than required. Given the variety of targets we need to support with the same code, the startup sequence is a bit of a jumble, and uses instructions and macros whose encoding widths cannot be specified (badr), or only exist in a narrow encoding (bx) So force the use of a wide encoding in __nop, and replace the start sequence with a simple jump to the label marking the start of code, preceded by a Thumb2 mode switch if required (using explicit wide encodings where appropriate). The label itself can be moved to the start of code [where it belongs] due to the larger range of branch instructions as compared to adr instructions. Reported-by:

This fixes a problem with reading files larger than 2GB from a UFS-2 file system: https://bugzilla.kernel.org/show_bug.cgi?id=195721 The incorrect UFS s_maxsize limit became a problem as of commit c2a9737f ("vfs,mm: fix a dead loop in truncate_inode_pages_range()") which started using s_maxbytes to avoid a page index overflow in do_generic_file_read(). That caused files to be truncated on UFS-2 file systems because the default maximum file size is 2GB (MAX_NON_LFS) and UFS didn't update it. Here I simply increase the default to a common value used by other file systems.
