2061 6679 d 6 h jermar /trunk/ Improve comments and fix formatting in (sparc64) TLS implementation.
Improve some comments and formatting in sparc64 uspace thread library
code.

Update required msim version.
 
2001 6710 d 21 h jermar /trunk/kernel/ Indentation and comment fixes.  
1950 6748 d 2 h jermar /trunk/kernel/ Indentation changes and coding style fixes in slab.c and slab.h.  
1915 6762 d 0 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 6814 d 8 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 6851 d 1 h decky / move kernel/trunk, uspace/trunk and boot/trunk to trunk/kernel, trunk/uspace and trunk/boot  
1761 6868 d 22 h jermar /kernel/trunk/doc/arch/ Upgrade amd64 hw compatibility list.  
1731 6874 d 19 h jermar /kernel/trunk/ Updates in Doxygen-style comments.
Make architecture specific modules appear conditionally in the documentation.
Add time management module.
Improve names of other modules and sort module order

1420 6896 d 9 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 6909 d 10 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 6978 d 23 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 6981 d 21 h jermar /kernel/trunk/ Upgrade toolchain build scripts to install binutils 2.16.1 and gcc 4.1.0.
