Hello,
This patch series adds S3 (suspend to RAM) ACPI state to BIOS. Most
changes concern themselves with preventing BIOS from using memory
locations available to a guest OS.
Changelog:
v2:
- Don't disable SMM.
- Jump to resume vector ASAP. Don't execute entire POST.
- Use smp_cpus directly for smp initialization instead of special memory
location.
v3:
- Stack pointer for rombios32 code depends on EBDA settings
- Fix .data and .rodata* section overlap
- Various small fixes
v4:
- If resume vector is NULL return to normal POST
---
Gleb Natapov (5):
Don't power down vga card on entering S3 state.
Don't use unreserved memory in BIOS.
Execute rombios32 code from rom address 0xe0000.
Preserve memory content during SMM init.
Add S3 state to DSDT. Handle resume event in the BIOS.
