Review changes committed to coreboot, virtualbox, qemu, kvm, and bochs
cvs tip.
- * bochs cvs 20081016: -- better post resume support
+ * bochs cvs 20081208: -- synched
* coreboot (r3348): 20060708 -- no noteworthy enhancements
- * qemu (r5536): 20080603 -- has cmos smp count
- * kvm (1a33292): 20071016 -- acpi dsdt changes, e820 vmx
+ * qemu (r6125): 20080603 -- acpi hpet table
+ * kvm (1a33292): 20081016 -- 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
post
-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.
+Possibly introduce a data type for the many seg/off pairs.
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.
+Implement bios post memory manager (PMM)?
+
+Add support for calling BCVs (and registering ATA drives) in a user
+selectable manor.
+
+Possibly add option to eliminate tsc based delays on emulators.
Add a kconfig style configuration program instead of requiring users
to modify config.h.
