1888 6476 d 21 h jermar /trunk/ C99 compliant header guards (hopefully) everywhere in the kernel.
Formatting and indentation changes.
Small improvements in sparc64.		  
1837 6518 d 6 h jermar /trunk/ Support 24bpp framebuffers with 4 pixelbytes (each pixel aligned on 32-bits).

At least on sparc64, the OpenFirmware linebytes property specifies the number
of pixels between consecutive scan lines of the display. Fix scanilne calculation,
including possible alignment.

Add note to 8bpp pixel functions pointing out drawbacks of that mode.		  
1812 6529 d 0 h decky /trunk/kernel/ move macro and cleanup  
1787 6541 d 20 h decky / move kernel/trunk, uspace/trunk and boot/trunk to trunk/kernel, trunk/uspace and trunk/boot  
1780 6548 d 21 h jermar /kernel/trunk/ Replace old __u?? types with respective C99 variants (e.g. uint32_t, int64_t, uintptr_t etc.).  
1742 6564 d 18 h palkovsky /kernel/trunk/arch/mips32/src/ Fix bad booting address on MIPS when not compiled in debug mode.  
1705 6569 d 3 h cejka /kernel/trunk/ Added file with modules definitions and descriptions.
We are able to change modules order and their description in one place.		  
1704 6569 d 6 h cejka /kernel/trunk/ Fixed first letter size of subgroup name in Others.  
1702 6570 d 0 h cejka /kernel/trunk/ Kernel doxygen comments updated.  
1686 6573 d 3 h decky /kernel/trunk/ update mips32 boot loading API  
1678 6573 d 23 h jermar /kernel/trunk/ Load up to 8 userspace tasks on mips32.  
1642 6576 d 4 h vana /kernel/trunk/arch/mips32/src/ System info about machine  
1537 6580 d 14 h palkovsky /kernel/trunk/ Added tetris to  
1474 6582 d 16 h palkovsky /kernel/trunk/ Added syscall that lets kernel regain access to keyboard.  
1458 6583 d 16 h palkovsky /kernel/trunk/ Added console support to gxemul.
Wider information in thread list.		  
1434 6585 d 20 h palkovsky /kernel/trunk/ Added 'realtime' clock interface.
Added some asm macros as memory barriers.
Added drift computing for mips platform.		  
1432 6586 d 3 h jermar /kernel/trunk/arch/mips32/src/ Load four userspace tasks on mips32.  
1396 6592 d 18 h palkovsky /kernel/trunk/ Fixed mips to compile with fb (missing hw_map).
Fixed mips hw virt/phys addresses of fb.
Moved fb_init to post_mm, because it needs malloc().		  
1354 6598 d 0 h palkovsky /kernel/trunk/ Support for mips kbd driver.  
1332 6599 d 18 h palkovsky /kernel/trunk/ Added support for more processes in mips.  
1222 6621 d 15 h decky /kernel/trunk/arch/ init tasks must be registered before main_bsp()  
1187 6630 d 21 h jermar /kernel/trunk/ Cleanup pm.c and pm.h code on ia32 and amd64.
Add before_task_runs() and before_task_runs_arch() for each architecture.
Add ia32 and amd64 code to ensure I/O Permission Bitmap update.		  
1122 6651 d 14 h palkovsky /kernel/trunk/arch/mips32/ Set up T9 to entry point on entry to userspace to facilitate better
PIC running.		  
1121 6651 d 17 h jermar /kernel/trunk/ Small textual changes.  
1112 6652 d 4 h palkovsky /kernel/trunk/ Added basic kernel infrastructure for ThreadLocalStorage(TLS) for
ia32(complete),amd64(complete),mips32(missing emulation of rdhwr instruction).		  
1078 6657 d 20 h jermar /kernel/trunk/ Improved uspace threads.
ia64 needs fixing.		  
1066 6658 d 13 h jermar /kernel/trunk/ Support for user space threads.  
1037 6659 d 3 h decky /kernel/trunk/ support for more init tasks
(might break some archs yet)		  
938 6662 d 20 h jermar /kernel/trunk/ Basic support for loading ELF object files.
ia64, amd64, ia32 working.
mips32 requires some attention.		  
897 6675 d 15 h jermar /kernel/trunk/ sparc64 work.
Fix KBD_VIRT_ADDRESS.
Call before_thread_runs() prior to the switch to the thread's stack. Add comment why this is crucial.
Add after_thread_ran() to the scheduler.
Add before_thread_runs_arch() and after_thread_ran_arch() for sparc64, mapping/demapping thread's kernel stack.
Add dummy after_thread_ran_arch() to all other architectures.
Add dtlb_insert_mapping() to promote code reuse.		  
853 6684 d 23 h palkovsky /kernel/trunk/arch/mips32/ Some arc bios tweaks. Wanted to print configuration data, but
the ARC seems to return strange values.
Newport graphics card does not seem to be easy to port, give up now.		  
817 6695 d 0 h palkovsky /kernel/trunk/ Small cleanup.  
814 6695 d 2 h palkovsky /kernel/trunk/ Cleanup o frame allocator.
Removed early_malloc & initial heap.
Will break ia64, ppc & sparc.
Added e820 table print.		  
812 6695 d 16 h jermar /kernel/trunk/ Documentation and dot.bochsrc upgrade.  
797 6696 d 21 h palkovsky /kernel/trunk/arch/mips32/ Fixed uspace address constants.  
796 6696 d 22 h palkovsky /kernel/trunk/ Gxemul support for mips userspace. MIPS now _must_ be started
always with userspace, there is (almost) no way how to pass parameters
to kernel.		  
794 6696 d 23 h palkovsky /kernel/trunk/ Added MIPS userspace. Currently can't make it work in gxemul.  
703 6721 d 2 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().		  
614 6752 d 13 h palkovsky /kernel/trunk/ Added support for mips breakpoints.
We have a kind of kernel debugger :-)
Breakpoints on JMP/Branch instructions are not supported and
they are reported after the breakpoint is fired and exited as
a BranchDelay exception. If we found a way, how to detect these
instructions, we would be able to support them as 'one-time' breakpoints.		  
590 6754 d 21 h palkovsky /kernel/trunk/ Move all MIPS exceptions to generic dispatcher.
Align size in malloc() to __native size, some architectures
don't like it unaligned.
