| 2008-07-28 | Remove dead code. | Miod Vallat | |
| 2008-07-28 | In process_write_regs() and sigreturn(), be more strict about the bits | Miod Vallat | |
| userland is allowed to change in psr. | |||
| 2008-07-28 | According to the manual, delay slot kill the benefits of being superscalar, | Miod Vallat | |
| so don't use any in the 88110-specific parts of locore. | |||
| 2008-07-21 | - add proper double_t and float_t definitions for each arch | Martynas Venckus | |
| - math.h shouldn't define FLT_EVAL_METHOD, but float.h should (per C99). remove from math.h, and add proper definitions in float.h ok millert@ | |||
| 2008-07-18 | Add a macro that clears the want_resched flag that need_resched sets. | Artur Grabowski | |
| Right now when mi_switch picks up the same proc, we didn't clear the flag which would mean that every time we service an AST we would attempt a context switch. For some architectures, amd64 being probably the most extreme, that meant attempting to context switch for every trap and interrupt. Now we clear_resched explicitly after every context switch, even if it didn't do anything. Which also allows us to remove some more code in cpu_switchto (not done yet). miod@ ok | |||
| 2008-06-14 | A bunch of pool_get() + bzero() -> pool_get(..., .. | PR_ZERO) | Michael Knudsen | |
| conversions that should shave a few bytes off the kernel. ok henning, krw, jsing, oga, miod, and thib (``even though i usually prefer FOO|BAR''; thanks for looking. | |||
| 2008-06-10 | Rename pmap_remove_all() to pmap_remove_page(). | Miod Vallat | |
| 2008-05-02 | Check for a disabled FPU before attempting to emulate the instruction. | Miod Vallat | |
| 2008-05-02 | Grab the biglock unconditionnaly when system calls go through systrace; | Miod Vallat | |
| spotted by drahn | |||
| 2008-04-25 | neccessary -> necessary; from Pierre Riteau | Jason McIntyre | |
| 2008-04-01 | typo | Miod Vallat | |
| 2008-02-20 | Preserve pcb_onfault within kcopy(), as expected and as all other platforms do. | Miod Vallat | |
| 2008-02-16 | On these platforms, REDUCEing unconditionnaly a second time is faster and | Miod Vallat | |
| shorter code than a conditional ADDCARRY, so use it; inspired by hppa. | |||
| 2008-01-13 | Add a machdep.cputype sysctl, which returns the processor type (0 for 88100, | Miod Vallat | |
| 1 for 88110), for userland to have an easy way to figure out. | |||
| 2007-12-31 | replace ctob/btoc by ptoa/atop as done for other architectures | Martin Reindl | |
| 2007-12-29 | Override SoftFloat's countLeadingZeros32() with a faster, ff1-based, version | Miod Vallat | |
| on m88k. | |||
| 2007-12-29 | Had I known we had a kernel version of John Hauser's SoftFloat code, I would | Miod Vallat | |
| have jumped on it instead of basing the FPU completion work on the sparc FPU code. This is now repaired with this commit, and m88110_fp.c changes directory again, for the last time. | |||
| 2007-12-26 | Remove the last debug bit from the PSR on 88110: do not force memory accesses | Miod Vallat | |
| instructions to be serialized (this defeats the purpose of having a superscalar processor, and accesses to volatile variables are done with explicit memory barriers anyway). This brings a HUGE speedup: openssl speed -elapsed shows AES is 90% faster, blowfish is 75% faster, and sha1 is 50% faster. Not so bad! However, doing this increases the pressure on the processor bus, so it is necessary to increase the processor bus timeout on 40MHz boards again (to 256 usec). ``black cat'' 50MHz boards seem to be unaffected, so they remain at 64 usec. | |||
| 2007-12-26 | Honour the rounding mode in fpu_ftoi(). | Miod Vallat | |
| 2007-12-26 | First try at getting the interval bits filled in fcmp{,u} results. | Miod Vallat | |
| 2007-12-26 | Fix FPU_SET_CARRY() | Miod Vallat | |
| 2007-12-25 | A few fixes in the exception bits reporting, spotted by John Hauser's TestFloat. | Miod Vallat | |
| 2007-12-25 | Zero / Num should return a zero with the same sign as the divider. | Miod Vallat | |
| 2007-12-25 | Accept valid forms of double-precision fmul/fadd/fsub/fdiv and reject invalid | Miod Vallat | |
| forms of fcvt where source and destination precision is the same. | |||
| 2007-12-25 | Missing pointer initialization for int/nint/trnc exceptions. | Miod Vallat | |
| 2007-12-25 | Never write boolean expressions which do not fit in one line, after midnight. | Miod Vallat | |
| 2007-12-25 | Do not make struct pmap visible unless _KERNEL. | Miod Vallat | |
| 2007-12-25 | Restart the m88110 floating-point trap code from scratch, basing it on the | Miod Vallat | |
| sparc{,64} floating-point emulator, adapted to the 88110 specifics. Handling of these traps is now entirely done in C for convenience. Although there are a few rounding issues to address, and the XRF is ignored, this allows all the ieee754 regression tests to pass (lib/libc/ieeefp, sys/kern/signal/fpsig, sys/kern/signal/sigfpe). | |||
| 2007-12-22 | Make sure we have a real stack when invoking getipl() during exceptions. | Miod Vallat | |
| Fits in the brown-paperbag bug category. | |||
| 2007-12-22 | Move initial PSR initialization to a separate routine, instead of duplicating | Miod Vallat | |
| it five times. | |||
| 2007-12-21 | Change the EF_xxx constants to be real offsets within the trapframe, instead | Miod Vallat | |
| of offsets / sizeof(register_t), and nuke the REG_OFF macro. No functional change. | |||
| 2007-12-20 | Get rid of disable_interrupt() and have caller use get_psr() and set_psr(); | Miod Vallat | |
| this allows us to get rid of the dependency of asm_macro.h on asm.h, which was really only there to bring in psl.h. | |||
| 2007-12-20 | Do not protect this file with _KERNEL; other header files which include it do it | Miod Vallat | |
| in a _KERNEL-only section, and we want to eventually be able to use it from the bootblocks. | |||
| 2007-12-20 | Flush the source page before copying in pmap_copy_page(). This should not | Miod Vallat | |
| be necessary, but not doing it appears to break 88204 (not 88200) and split CMMUs. | |||
| 2007-12-15 | Since the 88110 can not invalidate a particular tlb entry, do not stack | Miod Vallat | |
| invalidate tlb ipis, and turn them into simple ``handle once'' ipis. | |||
| 2007-12-15 | Move the cmmu lock back from 8820x-specific code to global, and use it on | Miod Vallat | |
| MVME197DP to serialize 88410 operations. | |||
| 2007-12-12 | Make non-88110 kernels (aviion, luna88k) kernels compile again. | Miod Vallat | |
| 2007-12-09 | I honestly do not remember what 88110 errata convinced me to disable | Miod Vallat | |
| out-of-order (superscalar) execution on these processors. Since OoO brings a nice 50% to 250% speedup (as shown by ``openssl speed''), it is definitely worth enabling. | |||
| 2007-12-08 | Better siginfo fault codes for floating point exceptions on 88110, with | Miod Vallat | |
| more work in progress to handle these exceptions correctly, and document a new undocumented and evil chip bug while there. | |||
| 2007-12-08 | Do not pass a siginfo_t * pointer to the signal handler if no siginfo | Miod Vallat | |
| is required. | |||
| 2007-12-05 | Make the CPU_88100 and CPU_88110 constants match the architectural number | Miod Vallat | |
| field from the processor identification register; this allows .S code which needs to decide on the cpu type at runtime to check quicker, without needing to access memory. No functional change. | |||
| 2007-12-05 | In dma_cachectl(), when flushing line by line, only invoke pmap_extract() | Miod Vallat | |
| once per page and cache the result. | |||
| 2007-12-05 | xmem can not be used as a reliable atomic operation, they way we do them, | Miod Vallat | |
| so do the naive operations with interrupts disabled, and an interlock held if MULTIPROCESSOR. | |||
| 2007-12-04 | Work in progress SMP code for 88110 processor using the BusSwitch chip as | Miod Vallat | |
| an IPI facility, for MVME197DP. It's still missing a few remote cache IPIs and IPI do not seem to be reliably triggered on remote processors at the moment (but this could be a problem on the board I am currently testing on), at least it will boot multiuser using only cpu0 to schedule processes. | |||
| 2007-12-04 | In double_reg_fixup(), do not rely on tf_r[0] being zero. | Miod Vallat | |
| 2007-12-04 | Improve setregs() so that it performs the equivalent of the first two | Miod Vallat | |
| instructions of the new binary, which allows them to be skipped unconditionaly. | |||
| 2007-12-04 | Faster splassert_check() | Miod Vallat | |
| 2007-12-04 | Fix userland vs system test in errata #16 handling. | Miod Vallat | |
| 2007-12-02 | Do not take biglock for NOLOCK system calls. | Miod Vallat | |
| 2007-12-02 | Only check for errata #16 for instruction faults. | Miod Vallat | |
