116 6959 d 6 h jermar /SPARTAN/trunk/ Add map_structure() to automate mapping of memory structures that can span multiple pages and/or cross page boundaries.
Change ACPI map_sdt() to use map_structure().

Small changes in MPS code.
The extra frame allocation for accessing frame 0 is unnecessary as it is possible to access frame 0 from kernel address space.
Zero TSS descriptor in the newly prepared GDT.

113 6962 d 21 h jermar /SPARTAN/trunk/ SMP recovery patch #2 (SMP is no longer broken !!!).
Fix missing KA2PA() operation in ap.S which was causing page faults during AP early initialization.
Fix bug in map_page_to_frame(): 'root' was interpretted as kernel address while read_dba() returns physical address.
Make references to page directory and page tables use kernel addresses instead of physical addresses.

Massive frame allocation code cleanup.
Basically revert to what we had had before implementation of userspace.

Usual cosmetics.

110 6964 d 7 h jermar /SPARTAN/trunk/ SMP recovery patch #1. (SMP still broken)
Move ap_boot() to K_TEXT_START_2 section.
Change ap_boot() to cope with mapping of kernel address space.
Change some addresses in mps.c from kernel to physical.

MIPS.
Move msim dprinter device to 0xB0000000.
This address is from kseg1 (unmapped, uncached) segment.

Introduce 'root' parameter of map_page_to_frame().
If 'root' is zero, page directory address is read from CPU.
Otherwise 'root' is used as page directory address.

106 6966 d 9 h jermar /SPARTAN/trunk/ IA-32 fixes.
Use kernel addresses instead of physical addresses in map_page_to_frame().
Physical addresses are supposed to only be exported to mm hardware.
Because of this fix, userspace is functional again.

Remap EGA videoram to (0x80000000 + videoram) and change the ega driver to work with the new address.

Minor cosmetics through out the code.
Changes in linker scripts.

105 6966 d 22 h jermar /SPARTAN/trunk/ Big changes in IA-32 address space map.
Now the kernel is mapped above 0x80000000. Finally!
Userspace address space starts at 0x00000000.
Changes in many places.
This improvement temporarily breaks SMP and most likely also other stuff.
Supported size of memory is now only 4M as it is the biggest size that can be mapped at once on IA-32.

Changes in linker script.
Changes required because of the above.
Do not patch hardcoded_* variables but assign to them instead.

Cosmetic changes here and there.

102 6972 d 2 h jermar /SPARTAN/trunk/ IA-64 work.
Redefine FRAME_SIZE to "(16*1024)" instead of "2*4096". Note that the latter definition was wrong because of the lack of "()".
Take panic_printf(), cpu_halt() and memsetb() out of fake.s and implement them properly in asm.S.
Move ski_init_console() from arch_post_mm_init() to arch_pre_mm_init().
In start.S, write r0 to ar.bspstore.

Janitorial fixes.
Add count_t type.
Replace several occurrences of int and __u32 by count_t or size_t.
Shorten several panic strings.
