1822	6499 d 11 h	jermar	/trunk/	sparc64 work. 1. Formatting fixes. 2. When writing to DMMU ASI's, simple membar() can be used in place of flush(). 3. Substantial changes in the way the TLB is taken over. 4. Remove unneeded functions. This is the first revision that also runs on a real world Ultra 5 with UltraSPARC IIi processor. Note that 3. needs further work as the current implementation depends on the fact that the compiler will use registers for local variables in take_over_tlb_and_tt(). Rewrite of that function into assembly is to follow.
1790	6518 d 5 h	jermar	/trunk/	Remove OpenFirmware calls from kernel/ entirely. Switch the sparc64 port to use bootinfo. Copy memcpy from boot/ to sparc64 kernel/ and adjust it for memcpy_from/to_uspace.
1787	6520 d 4 h	decky	/	move kernel/trunk, uspace/trunk and boot/trunk to trunk/kernel, trunk/uspace and trunk/boot
1784	6521 d 1 h	jermar	/kernel/trunk/	Sync OpenFirmware functionality with boot. Random cleanup.
1769	6530 d 1 h	jermar	/kernel/trunk/arch/	Change cache_error exception to take istate * as a parameter. Make cache_error() print epc in the panic message. Do not rely on the compiler to generate 'nop' after 'beq' in atomic_add() and put it there explicitly. Indentation fixes and cosmetic changes.
1702	6548 d 8 h	cejka	/kernel/trunk/	Kernel doxygen comments updated.
1410	6568 d 9 h	jermar	/kernel/trunk/arch/sparc64/	Modify sparc64 to choose optimal page size in each invocation of hw_map(). Use hw_map() to map keyboard device memory.
1382	6572 d 1 h	decky	/kernel/trunk/	make hardware memory mapping more generic
1376	6573 d 9 h	jermar	/kernel/trunk/	Change the way the framebuffer is mapped so that sparc64 is usable again.
1135	6628 d 0 h	decky	/kernel/trunk/	framebuffer code cleanup, support for non-standard scanline sizes ppc32: get framebuffer parameters from boot loader
897	6653 d 22 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.
895	6654 d 2 h	jermar	/kernel/trunk/	sparc64 work. Very raw and fragile preliminary standalone keyboard support - polling mode only. Because of a workaround in Simics, the scan codes are the same as on ia32.
894	6654 d 5 h	jermar	/kernel/trunk/	Move i8042 driver to genarch as it might be used by more architectures.
893	6654 d 10 h	jermar	/kernel/trunk/arch/	sparc64 work. Revive OFW console code and use it before the kernel switches to standalone console. ia32 + ia64 cosmetic changes.
883	6655 d 10 h	jermar	/kernel/trunk/arch/sparc64/	sparc64 work. Switch console to framebuffer (needs proper detection and initialization). No native keyboard support, so far. Memory management trap handler fixes. Do not use OpenFirmware trap table anymore.
669	6713 d 0 h	jermar	/kernel/trunk/	sparc64 work. kconsole support. Add non-blocking ofw_getchar().
664	6717 d 21 h	jermar	/kernel/trunk/	sparc64 work. Interrupt Levels 1 - 15 serviced. Minor changes in the exc_* functions.
586	6733 d 6 h	jermar	/kernel/trunk/	Fix ppc32 and sparc64 to compile again. Fix sparc64 to function again.
534	6739 d 3 h	jermar	/	Rename HelenOS/SPARTAN to HelenOS/kernel again.
532	6739 d 3 h	jermar	/	Revert renaming of HelenOS/SPARTAN to HelenOS/kernel because of important pending patch.
501	6751 d 7 h	jermar	/	Rename HelenOS/SPARTAN to HelenOS/kernel.
493	6752 d 0 h	jermar	/SPARTAN/trunk/	Move genarch/{src\|include}/firmware/ofw to genarch/{src\|include}/ofw.
426	6774 d 9 h	jermar	/SPARTAN/trunk/	sparc64 work. Add context_save(), context_set() and context_restore(). Remove putchar() definition from ofw.c. Add sparc64 putchar(). Add ppc32 putchar() (i.e. the original ofw.c putchar()). Make arg.h use the builtin va_* constructs.
