869 6651 d 0 h vana /kernel/trunk/ Uaaaaaaa ;-) Itanium Paging !!!!!! ;-)  
840 6658 d 10 h jermar /kernel/trunk/ Fix filling of hardcoded_ktext_size and hardcoded_kdata_size to use 64 bit stores on ia64.  
534 6731 d 4 h jermar / Rename HelenOS/SPARTAN to HelenOS/kernel again.  
532 6731 d 4 h jermar / Revert renaming of HelenOS/SPARTAN to HelenOS/kernel because of important pending patch.  
501 6743 d 8 h jermar / Rename HelenOS/SPARTAN to HelenOS/kernel.  
473 6756 d 1 h jermar /SPARTAN/trunk/arch/ia64/src/ ia64 work.
Comment some offending steps of heavyweight interrupt handler regarding RSE switching.
With this change, ia64 will do well on tests rwlock #4 and thread #1.
Cleanup.		  
412 6779 d 14 h jermar /SPARTAN/trunk/arch/ia64/src/ IA-64 work.
context_save() doesn't have to restore ar.pfs as it is a leaf procedure.
Get rid of assembler warning for start.S.		  
272 6823 d 6 h vana /SPARTAN/trunk/arch/ia64/ Symtab support for ia64  
249 6824 d 5 h vana /SPARTAN/trunk/arch/ia64/src/ Serialization of psr write  
106 6915 d 10 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.		  
102 6921 d 3 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.		  
81 6932 d 3 h jermar /SPARTAN/trunk/ Add SP_DELTA macro for each architecture.
On IA-32, this macro represents two doublewords that must be on the stack when switching to a new stack.
On MIPS, there is no need to fix sp when switching to a new stack.
On IA-64, this macro is used to allocate the 16-byte scratch area.

IA-64 work.
Changes in start.S. More changes to come.
Define memcopy().

Janitorial fixes.
Add missing #include <panic.h> to rwlock4/test.c.
Remove wrong use of inline keyword from both declaration and definition of l_apic_id().		  
78 6936 d 2 h jermar /SPARTAN/trunk/ IA-64 cosmetics.
Add ski_init_console() and ski_putchar() to ski.c to perform ski specific tasks.

Change the copyright string in main.c to display both copyrights on a new line.		  
74 6938 d 1 h jermar /SPARTAN/trunk/arch/ia64/src/ More of IA-64 initialization.  
60 6938 d 9 h jermar /SPARTAN/trunk/arch/ia64/ IA-64 work.
Give up attempts to persuade ld to patch the kernel image with proper hardcoded lenghts and addresses.
Add special sections and calculate the numbers manually.
Fix wrong order of operands in sub instructions in memcpy() implementation.		  
51 6941 d 4 h jermar /SPARTAN/trunk/ Small changes, fix last few wrong indentations.
TODO cleanup.

IA-64 bits.
Call main_bsp from kernel_image_start().
Prepare for IA-64 context_save and context_restore.		  
39 6945 d 1 h jermar /SPARTAN/trunk/arch/ia64/ IA-64 cosmetics.
Fix boot/boot.s to jump to the appropriate address.
Revert _link.ld to contain previously deleted sections.		  
37 6946 d 12 h jermar /SPARTAN/trunk/ More IA-64 work.
IA-64 putchar() for Ski simulator.
Linker script changes.		  
36 6947 d 4 h jermar /SPARTAN/trunk/arch/ia64/ More IA-64 work.  
35 6948 d 12 h jermar /SPARTAN/trunk/ Early support for IA-64 architecture.
