BTF encoder:
|
|
|
|
Andrii Nakryiko <andriin@fb.com>:
|
|
|
|
- Preserve and encode exported functions as BTF_KIND_FUNC.
|
|
|
|
Add encoding of DWARF's DW_TAG_subprogram_type into BTF's BTF_KIND_FUNC
|
|
(plus corresponding BTF_KIND_FUNC_PROTO). Only exported functions are converted
|
|
for now. This allows to capture all the exported kernel functions, same subset
|
|
that's exposed through /proc/kallsyms.
|
|
|
|
BTF loader:
|
|
|
|
Arnaldo Carvalho de Melo <acme@redhat.com>
|
|
|
|
- Add support for BTF_KIND_FUNC
|
|
|
|
Some changes to the fprintf routines were needed, as BTF has as the
|
|
function type just a BTF_KIND_FUNC_PROTO, while DWARF has as the type for a
|
|
function its return value type. With a function->btf flag this was overcome and
|
|
all the other goodies in pfunct are present.

Arnaldo Carvalho de Melo:
|
|
|
|
- Account inline type __aligned__ member types for spacing:
|
|
|
|
union {
|
|
refcount_t rcu_users; /* 2568 4 */
|
|
struct callback_head rcu __attribute__((__aligned__(8))); /* 2568 16 */
|
|
- } __attribute__((__aligned__(8))); /* 2568 16 */
|
|
+ } __attribute__((__aligned__(8))); /* 2568 16 */
|
|
struct pipe_inode_info * splice_pipe; /* 2584 8 */
|
|
|
|
- Fix alignment of class members that are structs/enums/unions
|
|
|
|
E.g. look at that 'completion' member in this struct:
|
|
|
|
struct cpu_stop_done {
|
|
atomic_t nr_todo; /* 0 4 */
|
|
int ret; /* 4 4 */
|
|
- struct completion completion; /* 8 32 */
|
|
+ struct completion completion; /* 8 32 */
|
|
|
|
/* size: 40, cachelines: 1, members: 3 */
|
|
/* last cacheline: 40 bytes */
|
|
|
|
- Fixup handling classes with no members, solving a NULL deref.
|
|
|
|
Gareth Lloyd <gareth.lloyd@uk.ibm.com>:
|
|
|
|
- Avoid infinite loop trying to determine type with static data member of its own type.
|
|
|
|
RPM spec file.
|
|
|
|
Jiri Olsa <jolsa@redhat.com>
|
|
|
|
Add dwarves dependency on libdwarves1.
|
|
|
|
pfunct:
|
|
|
|
Arnaldo Carvalho de Melo <acme@redhat.com>
|
|
|
|
- type->type == 0 is void, fix --compile for that
|
|
|
|
We were using the fall back for that, i.e. 'return 0;' was being emitted
|
|
for a function returning void, noticed with using BTF as the format.
|
|
|
|
pdwtags:
|
|
|
|
- Print DW_TAG_subroutine_type as well
|
|
|
|
So that we can see at least via pdwtags those tags, be it from DWARF of BTF.
|
|
|
|
core:
|
|
|
|
Arnaldo Carvalho de Melo <acme@redhat.com>
|
|
|
|
Fix ptr_table__add_with_id() handling of pt->nr_entries, covering how
|
|
BTF variables IDs are encoded.
|
|
|
|
|
|
pglobal:
|
|
|
|
Arnaldo Carvalho de Melo <acme@redhat.com>:
|
|
|
|
- Allow passing the format path specifier, to use with BTF
|
|
|
|
I.e. now we can, just like with pahole, use:
|
|
|
|
pglobal -F btf --variable foo.o
|
|
|
|
To get the global variables.
|
|
|

Tree wide:
|
|
|
|
Arnaldo Carvalho de Melo <acme@redhat.com>:
|
|
|
|
- Fixup issues pointed out by various coverity reports.
