3150 5854 d 17 h svoboda /branches/dynload/ Merge trunk changes up to r3090 into dynload (still broken)  
3149 5854 d 18 h svoboda /branches/dynload/ Merge trunk changes up to r3071 into dynload (broken)  
3001 5876 d 16 h svoboda /branches/dynload/kernel/generic/ Kernel support for running programs from userspace.  
2984 5879 d 17 h svoboda /branches/dynload/ Add as_area_change_flags() syscall and libc wrapper. Implementation limited to non-shared areas of anonymous memory.  
2952 5884 d 10 h svoboda /branches/dynload/ Load rtld.so with iloader and make it write to console with a stripped-down version of the C library  
2931 5886 d 18 h svoboda /branches/dynload/kernel/generic/src/syscall/ Fix format specifier when printing unknown syscall id  
2927 5886 d 21 h decky /branches/dynload/ added dynload branch  
2619 6063 d 9 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 6063 d 21 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 6064 d 18 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 6067 d 14 h jermar /trunk/ Start support for six syscall arguments.
This breaks all architectures.		  
2467 6223 d 13 h jermar /trunk/ Improve comments for arch-specific implementations of hierarchical
4-level page tables. Improve formatting.		  
2216 6290 d 11 h decky /trunk/ make thread ID 64 bit (task ID is 64 bit already)
cleanup thread syscalls		  
2187 6291 d 18 h decky /trunk/kernel/generic/ add syscall for getting current thread ID  
2119 6351 d 16 h decky /trunk/kernel/generic/src/syscall/ explicit typecast  
2089 6359 d 17 h decky /trunk/ huge type system cleanup
remove cyclical type dependencies across multiple header files
many minor coding style fixes		  
2071 6370 d 10 h jermar /trunk/ (c) versus (C)  
1888 6495 d 13 h jermar /trunk/ C99 compliant header guards (hopefully) everywhere in the kernel.
Formatting and indentation changes.
Small improvements in sparc64.		  
1862 6508 d 14 h jermar /trunk/kernel/ sparc64 work.
Kernel syscall support.
Modify the preemptive_handler for the use by syscalls.		  
1822 6539 d 19 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.
