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
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
Possibly implement 32bit pcibios support.
Allow one to select adding 32 bit code to 0xf000 or in a separate
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
Add a graphical boot splash screen?
