1126	6661 d 20 h	palkovsky	/kernel/trunk/arch/mips32/src/	Fix bad order of EPC & STATUS change in syscall_shortcut.
1122	6662 d 8 h	palkovsky	/kernel/trunk/arch/mips32/	Set up T9 to entry point on entry to userspace to facilitate better PIC running.
1121	6662 d 11 h	jermar	/kernel/trunk/	Small textual changes.
1119	6662 d 11 h	palkovsky	/kernel/trunk/arch/	Fixed bad rflags masking in amd64. Added TLS get address instruction emulation for mips.
1112	6662 d 22 h	palkovsky	/kernel/trunk/	Added basic kernel infrastructure for ThreadLocalStorage(TLS) for ia32(complete),amd64(complete),mips32(missing emulation of rdhwr instruction).
1102	6664 d 10 h	palkovsky	/kernel/trunk/arch/	Keep $K1 register for use as a thread local storage pointer on MIPS.
1100	6665 d 12 h	palkovsky	/kernel/trunk/	Cleanup of spinlocks, now compiles both ia32 and amd64 with and without DEBUG_SPINLOCKS. Made spinlocks inline. Moved syscall_handler to generic (it was identical for ia32,amd64 & mips32). Made slightly faster syscall for ia32. Made better interrupt routines for ia32. Allow not saving non-scratch registers during interrupt on ia32,amd64,mips32. Aligned interrupt handlers on ia32,amd64, this should prevent problems with different instruction lengths.
1097	6665 d 19 h	palkovsky	/kernel/trunk/arch/mips32/src/	Still better syscall calling convention for mips.
1096	6665 d 19 h	palkovsky	/kernel/trunk/	Cleanup of mips - inline register reads - better fpu disable/enable - global settings is automatically propagated to task - fast syscall
1094	6665 d 22 h	palkovsky	/kernel/trunk/	Allowed saving less registers.
1078	6668 d 14 h	jermar	/kernel/trunk/	Improved uspace threads. ia64 needs fixing.
1066	6669 d 7 h	jermar	/kernel/trunk/	Support for user space threads.
1044	6669 d 20 h	jermar	/kernel/trunk/	Page table locking.
1037	6669 d 21 h	decky	/kernel/trunk/	support for more init tasks (might break some archs yet)
983	6671 d 17 h	palkovsky	/kernel/trunk/	Fixed shrinking of as area.
959	6672 d 12 h	palkovsky	/kernel/trunk/	New synchronous ipc. Widened syscall to support up to 5 parameters.
958	6672 d 12 h	jermar	/kernel/trunk/	Nicer ia32 interrupt handlers and structures holding interrupted context data. Unify the name holding interrupted context data on all architectures to be istate.
955	6672 d 13 h	palkovsky	/kernel/trunk/	Added kernel IPC functionality.
938	6673 d 14 h	jermar	/kernel/trunk/	Basic support for loading ELF object files. ia64, amd64, ia32 working. mips32 requires some attention.
924	6674 d 0 h	palkovsky	/kernel/trunk/arch/mips32/	Macro redefinition for mips fpu.
906	6683 d 8 h	palkovsky	/kernel/trunk/	Added lazy fpu context allocation. - threads that don't use fpu, don't get allocated fpu context - fpu context alignment on AMD64 nicely disappeared
897	6686 d 8 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	6695 d 17 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.
852	6695 d 18 h	palkovsky	/kernel/trunk/	Fixes in memory allocator - proper kernel blacklisting, when kernel not loaded on page boundary - correct zone adding in zone list (how could this work??)
851	6696 d 11 h	palkovsky	/kernel/trunk/arch/mips32/src/	removed debugging printf.
850	6696 d 11 h	palkovsky	/kernel/trunk/	Small bugs fixed after running all tests on mips.
838	6699 d 22 h	palkovsky	/kernel/trunk/	Added untested support for 2 & 4-byte (15-bit & 24-bit depth) framebuffer.
837	6699 d 22 h	palkovsky	/kernel/trunk/	Moved framebuffer to genarch.
836	6700 d 9 h	palkovsky	/kernel/trunk/	Added support for 24-bit framebuffer.
831	6703 d 16 h	jermar	/kernel/trunk/	Make use of one unused bit in PTE formats of amd64, ia32 and mips32 to store 1 in valid mappings. This helps to distinguish valid entries from not present entries with 0 content (i.e. not present entries with PFN 0 and other bits cleared).
830	6703 d 18 h	jermar	/kernel/trunk/	Make ASID FIFO for mips32 be allocated statically. Make ASID FIFO for sparc64 and ia64 be allocated dynamically. Fix ia64 to call asid_fifo_init(). All three architectures now call asid_fifo_init() from as_arch_init().
827	6704 d 9 h	palkovsky	/kernel/trunk/	Unimportant changes regarding FPU context.
820	6705 d 10 h	jermar	/kernel/trunk/	Convert size_t, count_t and index_t to 64-bits on 64-bit architectures. Change some pfn_t usages to count_t, size_t and index_t.
817	6705 d 18 h	palkovsky	/kernel/trunk/	Small cleanup.
815	6705 d 19 h	jermar	/kernel/trunk/	Fix sparc64 and ia64 to work with the changed frame allocator. Fix ppc32 to at least compile.
814	6705 d 20 h	palkovsky	/kernel/trunk/	Cleanup o frame allocator. Removed early_malloc & initial heap. Will break ia64, ppc & sparc. Added e820 table print.
812	6706 d 10 h	jermar	/kernel/trunk/	Documentation and dot.bochsrc upgrade.
799	6707 d 11 h	palkovsky	/kernel/trunk/	Preliminary work on AMD userspace.
797	6707 d 15 h	palkovsky	/kernel/trunk/arch/mips32/	Fixed uspace address constants.
796	6707 d 16 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.
