3492 5727 d 8 h rimsky /branches/sparc/ Changes in trunk merged into the sparc branch. SILO's ramdisk issue solved by the CONFIG_RD_EXTERNAL option.  
3343 5783 d 10 h decky /branches/sparc/ add sparc branch  
3222 5825 d 11 h svoboda /trunk/ Merge program-loader related stuff from dynload branch to trunk. (huge)  
3113 5857 d 4 h decky /trunk/kernel/generic/ rename SYS_IO to SYS_KLOG
do not notify uspace klog with every single character, introduce some latency		  
3097 5859 d 8 h decky /trunk/kernel/ resurrect klog  
3096 5859 d 8 h svoboda /trunk/kernel/generic/src/syscall/ Fix malloc(0) in sys_io()  
3064 5860 d 12 h decky /trunk/kernel/generic/src/syscall/ change SYS_IO semantics
add SYS_TASK_SPAWN
proper printf formatting		  
2619 6056 d 5 h jermar /trunk/ Modify ipc_answer_*() to make use of all six syscall arguments. The recommended
means of answering calls is via the ipc_answer_m() macros (where m denotes the
number of return arguments) that automatically decide between the fast register
version or the slow universal version of ipc_answer().		  
2618 6056 d 18 h jermar /trunk/ Modify asynchronous IPC to make use of all six syscall arguments. The preferred
means of asynchronous communication is now via the set of ipc_call_async_m()
macros, where m is the number of payload arguments passed to the kernel. These
macros will automatically decide between the fast and the universal slow version
of ipc_call_async.		  
2615 6057 d 15 h jermar /trunk/ Modify synchronous IPC to make use of all six syscall arguments. The preferred
means of synchronous communication is now via the set of ipc_call_sync_m_n()
macros, where m is the number of payload arguments passed to the kernel and n is
the number of return values. These macros will automatically decide between the
fast and the universal slow version of ipc_call_sync.		  
2605 6060 d 11 h jermar /trunk/ Start support for six syscall arguments.
This breaks all architectures.		  
2467 6216 d 9 h jermar /trunk/ Improve comments for arch-specific implementations of hierarchical
4-level page tables. Improve formatting.		  
2216 6283 d 7 h decky /trunk/ make thread ID 64 bit (task ID is 64 bit already)
cleanup thread syscalls		  
2187 6284 d 14 h decky /trunk/kernel/generic/ add syscall for getting current thread ID  
2119 6344 d 12 h decky /trunk/kernel/generic/src/syscall/ explicit typecast  
2089 6352 d 13 h decky /trunk/ huge type system cleanup
remove cyclical type dependencies across multiple header files
many minor coding style fixes		  
2071 6363 d 6 h jermar /trunk/ (c) versus (C)  
1888 6488 d 10 h jermar /trunk/ C99 compliant header guards (hopefully) everywhere in the kernel.
Formatting and indentation changes.
Small improvements in sparc64.		  
1862 6501 d 10 h jermar /trunk/kernel/ sparc64 work.
Kernel syscall support.
Modify the preemptive_handler for the use by syscalls.		  
1822 6532 d 15 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.
