3343 5738 d 23 h decky /branches/sparc/ add sparc branch  
3249 5751 d 20 h jermar /trunk/kernel/doc/ Add Jiri Svoboda to AUTHORS and remove email addresses.  
3248 5751 d 20 h jermar /trunk/kernel/doc/ BUGS_FOUND is now out of date and it would require too much effort to keep it up
to date.
 
3228 5762 d 12 h decky /trunk/ physical memory detection in MSIM (discontinous regions supported)
remove Sgi Indy (ARC) support -- it was unmaintaned, untested for years and without uspace support
 
2500 6126 d 4 h jermar /trunk/kernel/ Make the kernel compile again after integrating the AVL tree.
Integrate with tests, add the AVL tree implementation author into AUTHORS.
 
2465 6177 d 1 h jermar /trunk/ Merge arm32 into trunk.  
2445 6184 d 2 h decky /trunk/ initial merge of branches/fs
(not finished, huge cleanup is needed)
 
2061 6337 d 3 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 6368 d 17 h jermar /trunk/kernel/ Indentation and comment fixes.  
1950 6405 d 22 h jermar /trunk/kernel/ Indentation changes and coding style fixes in slab.c and slab.h.  
1915 6419 d 20 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 6472 d 4 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 6508 d 22 h decky / move kernel/trunk, uspace/trunk and boot/trunk to trunk/kernel, trunk/uspace and trunk/boot  
1761 6526 d 18 h jermar /kernel/trunk/doc/arch/ Upgrade amd64 hw compatibility list.  
1731 6532 d 15 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
to be more like in the design documentation.
 
1705 6536 d 5 h cejka /kernel/trunk/ Added file with modules definitions and descriptions.
We are able to change modules order and their description in one place.
 
1543 6547 d 6 h palkovsky /kernel/trunk/doc/ Note about mips bug making tetris to fail.  
1422 6554 d 4 h jermar /kernel/trunk/ Modify ia64 linker script to make compilation with gcc 4.1.x possible.  
1420 6554 d 5 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 6567 d 7 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.
 
1297 6574 d 1 h jermar /kernel/trunk/ Add SYS_CAP_GRANT and SYS_CAP_REVOKE syscalls.
Move SYS_PREEMPT_CONTROL to ddi.c.
Add some comments and fix some small issues.
 
1229 6587 d 3 h jermar /kernel/trunk/ Remove the outdated TODO file.
Improve doxygen comments here and there.
 
1169 6600 d 18 h jermar /kernel/trunk/doc/ Change developer emails to their aliases in helenos.eu.  
912 6636 d 20 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 6639 d 18 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.
 
832 6659 d 18 h jermar /kernel/trunk/ Change pt_mapping_remove() to deallocate frames for empty PTL1, PTL2 and PTL3.  
822 6661 d 17 h palkovsky /kernel/trunk/ Changed malloc to include second parameter and documented
recommended usage.
Added zone merging, made ia32 & amd64 to merge found zones.
 
812 6662 d 18 h jermar /kernel/trunk/ Documentation and dot.bochsrc upgrade.  
761 6668 d 3 h jermar /kernel/trunk/doc/ Remove document describing more relaxed preemption model than the one used in the current kernel.  
750 6671 d 20 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.
 
703 6688 d 3 h jermar /kernel/trunk/ Memory management work.
- vm.* -> as.* (as like address space is, imho, more fitting)
- Don't do TLB shootdown on vm_install(). Some architectures only need to call tlb_invalidate_asid().
- Don't allocate all frames for as_area in as_area_create(), but let them be allocated on-demand by as_page_fault().
- Add high-level page fault handler as_page_fault().
- Add as_area_load_mapping().
 
681 6693 d 4 h jermar /kernel/trunk/ Minor changes.  
558 6725 d 2 h palkovsky /kernel/trunk/ Clean up of build system. Use:
make config
make
make clean
 
534 6727 d 20 h jermar / Rename HelenOS/SPARTAN to HelenOS/kernel again.  
532 6727 d 21 h jermar / Revert renaming of HelenOS/SPARTAN to HelenOS/kernel because of important pending patch.  
523 6734 d 0 h jermar /kernel/trunk/ Clean up.  
516 6737 d 21 h jermar /kernel/trunk/ Add VMware Workstation 5.5 to SMP compatibility list.
