2001 6520 d 16 h jermar /trunk/kernel/ Indentation and comment fixes.  
1915 6571 d 19 h jermar /trunk/kernel/ A quote from from SPARC V9 specification:

The Y register is deprecated; it is provided only for compatibility with previous versions
of the architecture. It should not be used in new SPARC-V9 software. It is
recommended that all instructions that reference the Y register (i.e., SMUL,
SMULcc, UMUL, UMULcc, MULScc, SDIV, SDIVcc, UDIV, UDIVcc, RDY, and
WRY) be avoided. See the appropriate pages in Appendix A, “Instruction Definitions,”
for suitable substitute instructions.

Still gcc is generating code which uses Y and some of the instructions above.
This change modifies the preemptible_handler() to preserve the Y register
across preemption.
 
1849 6624 d 3 h jermar /trunk/kernel/ sparc64 work.
interrupt_vector trap experimental handling.
Minimal reverse-engineered FireHose Controller driver (documentation needed!).
Keyboard on Sun Enterprise is now interrupt driven. Keyboard on Sun Ultra
is still polled.
 
1787 6660 d 21 h decky / move kernel/trunk, uspace/trunk and boot/trunk to trunk/kernel, trunk/uspace and trunk/boot  
1761 6678 d 17 h jermar /kernel/trunk/doc/arch/ Upgrade amd64 hw compatibility list.  
1422 6706 d 3 h jermar /kernel/trunk/ Modify ia64 linker script to make compilation with gcc 4.1.x possible.  
1420 6706 d 4 h jermar /kernel/trunk/ Upgrade toolchain to use gcc 4.1.1.
ia64 still cannot be built with combination of binutils 2.16.1 and gcc 4.1.x
 
1323 6719 d 6 h jermar /kernel/trunk/ Increase "timeout" for debugging spinlock so that false positive
deadlock reports are suppressed on real hardware.

Also add one HT configuration to hardware compatibility list.
 
912 6788 d 19 h jermar /kernel/trunk/ ia64 work.

ivt.S:
Detect userspace stack in heavyweight handler and switch to kernel stack.
Remember the old stack pointer.
As for register stack, kernel stack is assumed still.
Fix alignment issues that showed when STACK_ITEMS was odd.
Fix ld8 instruction that did subtraction of 8 instead of addition of 8.

scheduler.c:
Change before_thread_runs_arch() to calculate address of top of the stack
for the interrupt handler.
 
905 6791 d 16 h jermar /kernel/trunk/ Upgrade toolchain build scripts to install binutils 2.16.1 and gcc 4.1.0.
The only exception is ia64, where the kernel does not build with gcc 4.1.0.
 
812 6814 d 17 h jermar /kernel/trunk/ Documentation and dot.bochsrc upgrade.  
750 6823 d 19 h jermar /kernel/trunk/ ia32 SMP updates.
Update info about supported version of Bochs (bump the counter to 2.2.6).
Add Task Priority Register type and initialize this register to a known state.
 
681 6845 d 3 h jermar /kernel/trunk/ Minor changes.  
534 6879 d 19 h jermar / Rename HelenOS/SPARTAN to HelenOS/kernel again.  
532 6879 d 20 h jermar / Revert renaming of HelenOS/SPARTAN to HelenOS/kernel because of important pending patch.  
523 6885 d 23 h jermar /kernel/trunk/ Clean up.  
516 6889 d 20 h jermar /kernel/trunk/ Add VMware Workstation 5.5 to SMP compatibility list.  
501 6892 d 0 h jermar / Rename HelenOS/SPARTAN to HelenOS/kernel.  
436 6908 d 18 h decky /SPARTAN/trunk/doc/arch/ new tested IA-32 SMP machines  
410 6928 d 20 h jermar /SPARTAN/trunk/ Doxygen-style comments.  
398 6938 d 3 h jermar /SPARTAN/trunk/ Add arch directory for sparc64.  
365 6954 d 18 h jermar /SPARTAN/trunk/ Replace #define's in list.h with type-safe inlines.

Update mips32 documentation.
 
347 6961 d 19 h jermar /SPARTAN/trunk/ Documentation updates for amd64, mips32 and ia32.

Replace %L with %P printf() formatter in MPS and ACPI detection functions to print addresses in maximal width.

Tweak memmap.S and IA-32 and AMd64 boot.S.
Cancel unneeded instructions.
Replace cmpl $0, %ebx with testl %ebx, %ebx.
Move memmap.S data to K_DATA_START section.
 
346 6962 d 17 h jermar /SPARTAN/trunk/doc/ Update documentation of ports.  
341 6963 d 1 h jermar /SPARTAN/trunk/ Rename mips port to mips32.  
110 7062 d 0 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.
 
35 7097 d 4 h jermar /SPARTAN/trunk/ Early support for IA-64 architecture.
