| Review changes committed to coreboot, virtualbox, qemu, kvm, and bochs |
| cvs tip. |
| * bochs cvs 20081016: -- better post resume support |
| * coreboot (r3348): 20060708 -- no noteworthy enhancements |
| * qemu (r5536): 20080603 -- has cmos smp count |
| * kvm (1a33292): 20071016 -- acpi dsdt changes, e820 vmx |
| pages, setup mtrrs, clear tsc, acpi intsrcovr table, different pci |
| irqs, smbios always uses 16 cpus, no acpi ssdt, fadt->gpe0_blk set |
| * virtualbox (r13560): 20061231 -- lots of mouse changes, logo, |
| scsi/etherboot hooks, int 1589, floppy data rate?, int19 calls |

| |
| Look into ways to reduce stack usage. Alter ISRs so that they do not |
| enable irqs. Only call out to other bios functions after minimizing |
| stack usage. |
| |
| Audit all sti/cli calls. Audit all call16 calls to make sure flags is |
| setup properly with respect to irqs. |
| |
| Audit statements where a 32bit intermediary changes meaning of a 16bit |
| comparison. |
| |
| Code assumes ebda segment is static - it doesn't read 0x40e. |
| |
| The __call16 code does a long jump to the interrupt trampolines - this |
| is unnecessary. |
| |
| Cleanup setting of ES on GET/SET_BDA |
| |
| Audit code for 16bit protected mode accesses. Support 1ab1 from 16bit |
| protected mode. The BDA is technically at segment 0x0040 (not |
| 0x0000). |
| |
| Possibly implement 32bit pcibios support. |
| |
| Allow one to select adding 32 bit code to 0xf000 or in a separate |
| location. |
| |
| See if it is possible to handle interrupts while in 32bit mode. |
| |
| Add a kconfig style configuration program instead of requiring users |
| to modify config.h. |
| |
| Look at integrating the lgpl vgabios into tree. |
| |
| Look at usb booting specs. Look at possibly supporting usb |
| keyboard/mice. |
| |
| Add a graphical boot splash screen? |
