The shadow area must therefore occupy full PGD entries. The shadow area has a size of 128MB starting at 0xf8000000. With 4k pages, a PGD entry is 4MB With 16k pages, a PGD entry is 64MB With 64k pages, a PGD entry is 1GB which is too big. Until we rework the early shadow mapping, disable KASAN when the page size is too big.

Nowadays, we can use CONFIG_X86_CMPXCHG64 for this purpose. Also, by using try_cmpxchg64() instead of cmpxchg64() in the CMPXCHG_LOOP macro, the compiler actually produces sane code, improving the lockref_get_not_zero() main loop from: eb: 8d 48 01 lea 0x1(%eax),%ecx ee: 85 c0 test %eax,%eax f0: 7e 2f jle 121 <lockref_get_not_zero+0x71> f2: 8b 44 24 10 mov 0x10(%esp),%eax f6: 8b 54 24 14 mov 0x14(%esp),%edx fa: 8b 74 24 08 mov 0x8(%esp),%esi fe: f0 0f c7 0e lock cmpxchg8b (%esi) 102: 8b 7c 24 14 mov 0x14(%esp),%edi 106: 89 c1 mov %eax,%ecx 108: 89 c3 mov %eax,%ebx 10a: 8b 74 24 10 mov 0x10(%esp),%esi 10e: 89 d0 mov %edx,%eax 110: 31 fa xor %edi,%edx 112: 31 ce xor %ecx,%esi 114: 09 f2 or %esi,%edx 116: 75 58 jne 170 <lockref_get_not_zero+0xc0> to: 350: 8d 4f 01 lea 0x1(%edi),%ecx 353: 85 ff test %edi,%edi 355: 7e 79 jle 3d0 <lockref_get_not_zero+0xb0> 357: f0 0f c7 0e lock cmpxchg8b (%esi) 35b: 75 53 jne 3b0 <lockref_get_not_zero+0x90> Signed-off-by: Uros Bizjak <ubizjak@gmail.com> Signed-off-by: Ingo Molnar <mingo@kernel.org> Acked-by: Linus Torvalds <torvalds@linux-foundation.org> Link: https://lore.kernel.org/r/20230918184050.9180-1-ubizjak@gmail.com diff 606576ce Mon Oct 06 17:06:12 MDT 2008 Steven Rostedt <rostedt@goodmis.org> ftrace: rename FTRACE to FUNCTION_TRACER Due to confusion between the ftrace infrastructure and the gcc profiling tracer "ftrace", this patch renames the config options from FTRACE to FUNCTION_TRACER.

What happens is the "ftrace=..." will expand the ring buffer to its default size (from its minimum size) but it will not expand the max ring buffer (the ring buffer to store maximum latencies). When the irqsoff test runs, it will call the ring buffer swap routine that checks if the max ring buffer is the same size as the normal ring buffer, and will fail if it is not. This causes the test to fail. The solution is to expand the max ring buffer before running the self test if the max ring buffer is used by that tracer and the normal ring buffer is expanded. The max ring buffer should be shrunk again after the test is done to save space.

We can save 4 bytes per event by combining the two into a single integer. text data bss dec hex filename 4913961 1088356 861512 6863829 68bbd5 vmlinux.orig 4894944 1018052 861512 6774508 675eec vmlinux.id 4894871 1012292 861512 6768675 674823 vmlinux.flags This gives us another 5K in savings. The modification of both the enable and filter fields are done under the event_mutex, so it is still safe to combine the two. Note: Although Mathieu gave his Acked-by, he would like it documented that the reads of flags are not protected by the mutex. The way the code works, these reads will not break anything, but will have a residual effect. Since this behavior is the same even before this patch, describing this situation is left to another patch, as this patch does not change the behavior, but just brought it to Mathieu's attention. v2: Updated the event trace self test to for this change.
