0xFFFF800000000000 opened a new pull request, #18303:
URL: https://github.com/apache/nuttx/pull/18303
## Summary
This PR addresses an issue with the `gdt_flush` and `idt_flush` routines in
`arch/x86/src/486/i486_utils.S`.
Both routines previously had a logic error where `eax` was moved into the
stack slot of the first function parameter, instead moving the gdt/idt pointer
from the stack into eax:
```asm
movl %eax, 4(%esp)
lgdt (%eax)
```
This only did not crash because `eax` was not clobbered between where it was
pushed to the stack by the calling function, and its use in `lgdt` / `lidt`,
respectively:
#### gdt_flush call site (in up_lowsetup)
```asm
108e58: 50 push %eax
108e59: e8 f9 0f 00 00 call 109e57 <gdt_flush>
```
#### idt_flush call site (in up_irqinitialize)
```asm
1099a9: 50 push %eax
1099aa: e8 c5 04 00 00 call 109e74 <idt_flush>
```
## Impact
No direct impact, as the buggy code coincidentally still worked.
## Testing
- Host: Linux x86_64
- Board: qemu-i486:nsh
- ostest passed
