linux.git/arch/parisc/kernel/real2.S, branch for-next Linux kernel source tree parisc: Fix argument pointer in real64_call_asm() 2023-05-03T15:43:26+00:00 Helge Deller deller@gmx.de 2023-05-03T14:39:56+00:00 6e3220ba3323a2c24be834aebf5d6e9f89d0993f Fix the argument pointer (ap) to point to real-mode memory instead of virtual memory. It's interesting that this issue hasn't shown up earlier, as this could have happened with any 64-bit PDC ROM code. I just noticed it because I suddenly faced a HPMC while trying to execute the 64-bit STI ROM code of an Visualize-FXe graphics card for the STI text console.

Fix the argument pointer (ap) to point to real-mode memory
instead of virtual memory.

It's interesting that this issue hasn't shown up earlier, as this could
have happened with any 64-bit PDC ROM code.

I just noticed it because I suddenly faced a HPMC while trying to execute
the 64-bit STI ROM code of an Visualize-FXe graphics card for the STI
text console.

parisc: Fix and improve kernel stack unwinding 2018-08-13T07:54:17+00:00 Helge Deller deller@gmx.de 2018-08-04T22:03:29+00:00 c8921d72e390cb6fca3fb2b0c2badfda851647eb This patchset fixes and improves stack unwinding a lot: 1. Show backward stack traces with up to 30 callsites 2. Add callinfo to ENTRY_CFI() such that every assembler function will get an entry in the unwind table 3. Use constants instead of numbers in call_on_stack() 4. Do not depend on CONFIG_KALLSYMS to generate backtraces. 5. Speed up backtrace generation Make sure you have this patch to GNU as installed: https://sourceware.org/ml/binutils/2018-07/msg00474.html Without this patch, unwind info in the kernel is often wrong for various functions.
