2259 6286 d 6 h jancik /branches/arm/kernel/arch/arm32/include/mm/ settings flags update  
2258 6286 d 6 h jancik /branches/arm/kernel/arch/arm32/ page faults added, beta version  
2257 6286 d 6 h jancik /branches/arm/boot/arch/arm32/loader/ coding style  
2256 6286 d 22 h kebrt /branches/arm/kernel/arch/arm32/ few bugs in MM fixed (PAGE_PRESENT used badly) -> 2nd level paging now works; coding style  
2255 6286 d 22 h kebrt /branches/arm/kernel/genarch/src/mm/ PLTx_SIZE used instead of PAGE_SIZE in memsetb  
2254 6286 d 22 h kebrt /branches/arm/boot/arch/arm32/loader/ paging started at the beginning of booting (so KERNEL_VIRTUAL_ADDRESS used instead of KERNEL_PHY_ADDRESS); comments  
2253 6286 d 23 h jelen /branches/fs/uspace/tetris/ Revert a change from a wrong commit (2247 - cat task)  
2252 6286 d 23 h jermar /trunk/kernel/arch/sparc64/src/mm/ Move one MEMBAR instruction from a delay slot,
which is, due to SF Erratum #51, a potentionally
dangerous place for a MEMBAR to be.
 
2251 6287 d 0 h jelen /branches/fs/uspace/cat/ New cat task to dump a file content on console (testing for fs)  
2250 6287 d 0 h jermar /trunk/boot/ Fix ticket #31.  
2249 6288 d 21 h jelen /branches/fs/boot/arch/mips32/loader/ configuration with ramdisk  
2248 6288 d 21 h jelen /branches/fs/uspace/ Connecting services cat -> fs -> rd  
2247 6288 d 21 h jelen /branches/fs/ A new "cat" task to test "fs" (read a file and dump it onto the console)  
2246 6288 d 21 h jelen /branches/fs/kernel/generic/src/lib/ Go back to checking data size against frame size  
2245 6289 d 8 h stepan /branches/arm/kernel/arch/arm32/ irq dispatching
gxemul irq controller and timer "drivers"
 
2244 6289 d 12 h kebrt /branches/arm/kernel/arch/mips32/include/mm/ page has 16KB (ONE_FRAME used instead of FOUR_FRAMES)  
2243 6289 d 23 h kebrt /branches/arm/kernel/arch/arm32/ last_frame variable added (as in other archs), kernel page table created (not yet used)  
2242 6289 d 23 h kebrt /branches/arm/kernel/ ARM has 16kB first level page table, so PTL0..3_SIZE constants added to frame_alloc and all achitectures  
2241 6290 d 1 h kebrt /branches/arm/ comments & code standards & typo  
2240 6290 d 7 h jancik /branches/arm/kernel/arch/arm32/include/ Alf: reg r9 forgotten  
2239 6290 d 16 h jancik /branches/arm/boot/arch/arm32/loader/  
2238 6290 d 23 h kebrt /branches/arm/kernel/arch/arm32/ refactoring & comments & code standards  
2237 6290 d 23 h jermar /trunk/boot/arch/sparc64/silo/ Upgrade SILO to 1.4.13.  
2236 6291 d 1 h kebrt /branches/arm/boot/arch/arm32/loader/ refactoring & comments & code standards  
2235 6291 d 2 h stepan /branches/arm/kernel/arch/arm32/ exception handling
simple interrupt processing
 
2234 6292 d 2 h jancik /branches/arm/boot/arch/arm32/loader/ Alf: stabni kultura  
2233 6292 d 23 h decky /trunk/kernel/arch/ use the hlt instruction more properly  
2232 6293 d 0 h decky /trunk/kernel/arch/mips32/src/ add support for halt/reboot in MSIM  
2231 6293 d 4 h jermar /trunk/kernel/arch/sparc64/ Fix a nasty bug in the TLB miss handlers on sparc64.
After we no longer lock the kernel stack in the DTLB,
there is a real danger of nested DTLB misses. The nested
miss can very easily clobber the DTLB Tag Access register.
Therefore, the original miss may not read this register, but
it has to receive its value as an argument. The argument
value is saved in the trap table when it is guaranteed that
the nested TLB miss will not occur.
 
2230 6293 d 4 h jermar /trunk/uspace/ Remove printf() serialization from thread1 test in tester.
The agreement among developers seems to be that:
- there _must_ be a futex to serialize access to printf()
- there _must_ be pseudo thread serialization in printf()
- the best place for this is vprintf(), the one that goes to console
 
2229 6293 d 7 h jermar /trunk/ Revert some of the changes introduced in revision 2209.
I think it is not correct to remove serialization of pseudo threads in printf_core.c.
With thread-level futex serialization, several pseudo threads running in one thread could easily deadlock
the task.

Add a dedicated futex serialization to thread1.c test only.
 
2228 6293 d 7 h jermar /trunk/kernel/arch/sparc64/src/ Fix ticket #28.
In switch_to_userspace(), the uarg argument is in %i2, not in %i3.
 
2227 6293 d 14 h decky /trunk/kernel/ start shutdown infrastructure  
2226 6293 d 15 h decky /trunk/contrib/conf/ MIPS boot image has grown  
2225 6293 d 15 h decky /trunk/kernel/arch/mips32/ the bss and common sections have to be in .data output section to be properly generated in the binary image
(this might break IRIX, but it is already unmaintaned)
 
2224 6293 d 21 h decky /trunk/kernel/generic/src/console/ detach joined thread  
2223 6293 d 21 h decky /trunk/kernel/generic/src/ add mcall0 command (calling a function on each CPU)  
2222 6294 d 0 h decky /trunk/kernel/ map kernel pages explicitly as writable (this solves compatibility issues with Intel Core 2)
make VESA framebuffer initialization more robust
 
2221 6294 d 1 h decky /trunk/kernel/arch/ia32/src/boot/ fix typo in comment  
2220 6294 d 1 h decky /trunk/kernel/arch/ia32/src/boot/ check for PSE support, add error message on PSE not present
make initial mapping explicitly writeable, turn PAE explicitly off (just in case)
