Subject: [PATCH 1/3] Fix for the topa_entry issue
|
||||
|
||||
kernel commit 59388b9cbe20 ("[x86] perf/x86/intel/pt: Split ToPA metadata
|
||||
and page layout") moved out the table of topa entry from struct topa, which
|
||||
may cause the following failures:
|
||||
[1] invalid kernel virtual address: 0 type: "struct topa_entry"
|
||||
[2] current buffer not found
