2007-09-10 | Introduce a md pmap hook, pmap_remove_holes(), which is supposed to mark | Miod Vallat | |
the holes a MMU may have from a given vm_map. This will be automagically invoked for newly created vmspaces. On platforms with MMU holes (e.g. sun4, sun4c and vax), this prevents mmap(2) hints which would end up being in the hole to be accepted as valid, causing unexpected signals when the process tries to access the hole (since pmap can not fill the hole anyway). Unfortunately, the logic mmap() uses to pick a valid address for anonymous mappings needs work, as it will only try to find an address higher than the hint, which causes all mmap() with a hint in the hole to fail on vax. This will be improved later. | |||
2007-09-09 | Disable page zeroing in the idle loop, as it blasts the entire cache. | Miod Vallat | |
Spotted by kettenis | |||
2007-09-02 | Fix typos in comments: soruce -> source | Hans-Joerg Hoexer | |
2007-09-01 | In pmap_protect(), compute the bitmask to set in the ptes only once, instead | Miod Vallat | |
of every iteration. | |||
2007-07-11 | Remove unused shpcic_intr_establish() and friends. | Miod Vallat | |
2007-06-21 | Fix microtime to not lose clocik ticks, gives us among other things, real | Miod Vallat | |
ping times on slow links; from mickey | |||
2007-06-21 | Simple optimizations: | Miod Vallat | |
- in __pmap_pv_enter, only walk the pv list to search for writeable mappings if we are ading a readonly mapping. - im pmap_protect, do not invoke pmap_extract(), instead directly extract the paddr from the pte we have already computed a few lines above. | |||
2007-06-21 | Attach interrupt counters to intc interrupt sources too, so that clock | Miod Vallat | |
interrupts get counted; from mickey | |||
2007-06-20 | b_cylinder does not need to be set on the callpath down into drivers. | Theo de Raadt | |
cpu_disklabel can go away, since nothing anymore needs to use it; ok miod | |||
2007-06-17 | significantly simplified disklabel infrastructure. MBR handling becomes MI | Theo de Raadt | |
to support hotplug media on most architectures. disklabel setup and verification done using new helper functions. Disklabels must *always* have a correct checksum now. Same code paths are used to learn on-disk location disklabels, to avoid new errors sneaking in. Tested on almost all cases, testing help from todd, kettenis, krw, otto, dlg, robert, gwk, drahn | |||
2007-06-06 | now that all partition size/offsets are potentially 64-bit, change the | Theo de Raadt | |
type of all variables to daddr64_t. this includes the APIs for XXsize() and XXdump(), all range checks inside bio drivers, internal variables for disklabel handling, and even uvm's swap offsets. re-read numerous times by otto, miod, krw, thib to look for errors | |||
2007-05-29 | start of dumpconf() unification, which one day we can pray will be MI | Theo de Raadt | |
(and part of setroot); ok miod | |||
2007-05-29 | Use atomic operations to operate on netisr, instead of clearing it at splhigh. | Miod Vallat | |
This changes nothing on legacy architectures, but is a bit faster (and simpler) on the interesting ones. | |||
2007-05-28 | Move the MSIZE, MCLSHIFT, MCLBYTES and the MCLOFSET | Thordur I. Bjornsson | |
mbuf constants from MD param.h to MI param.h. Besides being the same on every arch, things will most probly break if any arch has different values then the others. The NMBCLUSTERS constants needs to be MD though; ok miod@,krw@,claudio@ | |||
2007-05-27 | pagemove() is no longer used. | Miod Vallat | |
2007-05-27 | Make sure the minaddr hint for uvm_km_suballoc() calls is always initialized. | Miod Vallat | |
ok pedro@ | |||
2007-05-26 | Dynamic buffer cache. Initial diff from mickey@, okay art@ beck@ toby@ | Pedro Martelletto | |
deraadt@ dlg@. | |||
2007-05-26 | tyops | Miod Vallat | |
2007-05-20 | Fix KERNBASE, so that profiling kernels initialize (but profiling is broken | Miod Vallat | |
at the moment). | |||
2007-05-18 | Instead of checking whichqs directly, add a "sched_is_idle()" macro to | Artur Grabowski | |
sys/sched.h and use that to check if there's something to do. kettenis@ thib@ ok | |||
2007-05-16 | The world of __HAVEs and __HAVE_NOTs is reducing. All architectures | Artur Grabowski | |
have cpu_info now, so kill the option. eyeballed by jsg@ and grange@ | |||
2007-05-15 | Remove the MI implementation of mutexes and remove the __HAVE_MUTEX | Artur Grabowski | |
option. Every architecture implements mutexes now. | |||
2007-05-14 | Switch sh to __HAVE_CPUINFO. The least possible effort for now. | Artur Grabowski | |
deraadt@ ok | |||
2007-05-10 | evcnt & friends were replaced by a proper interrupt counting mechanism 3 ↵ | Theo de Raadt | |
years ago; ok miod | |||
2007-05-05 | Define MUTEX_OLDIPL where they were missing, will be used (reasonably) shortly. | Miod Vallat | |
2007-05-01 | Simple monoprocessor mutex implementation, faster than the MI code, four left | Miod Vallat | |
to go. | |||
2007-04-29 | machdep.led_blink sysctl for landisk, also move cpu_sysctl() code and related | Miod Vallat | |
variables from arch/sh/ to arch/landisk/. ok deraadt@ | |||
2007-04-05 | Disable interrupts around bit operations for propert atomicity against them. | Miod Vallat | |
2007-03-19 | Default to writeback cache. | Miod Vallat | |
2007-03-17 | Do not start lines printed by the kernel with '<' so that syslog won't get | Miod Vallat | |
confused. | |||
2007-03-15 | Since p_flag is often manipulated in interrupts and without biglock | Artur Grabowski | |
it's a good idea to use atomic.h operations on it. This mechanic change updates all bit operations on p_flag to atomic_{set,clear}bits_int. Only exception is that P_OWEUPC is set by MI code before calling need_proftick and it's automatically cleared by ADDUPC. There's no reason for MD handling of that flag since everyone handles it the same way. kettenis@ ok | |||
2007-03-13 | Move UKC later in the boot process, so that it can use malloc(). | Miod Vallat | |
2007-03-13 | It is safe to run tlb_exception() at the pre-fault ipl. | Miod Vallat | |
2007-03-05 | Add pmap_prefer() for SH4, from NetBSD; ok drahn@ | Miod Vallat | |
2007-03-05 | Prevent a NULL pointer dereference in __pmap_kptp_lookup(); from NetBSD | Miod Vallat | |
2007-03-05 | Lower the ipl to what it was at the time of the trap in general_exception, | Miod Vallat | |
instead of remaining at splhigh; from NetBSD ok drahn@ | |||
2007-03-05 | Work around a virtual aliasing conflict issue. Basically allow multiple | Dale Rahn | |
readers but only one writer on a physical page. Not the most optimal, but has been tested. ok miod@ | |||
2007-03-03 | Kernel crash dumps and associated libkvm bits for landisk. | Miod Vallat | |
2007-03-02 | Move landisk to hardware floating point. At the moment the FPU context is | Miod Vallat | |
always saved upon context switches, as FPU registers are heavily used for long long computations (don't ask). Gcc default to -m4. Credits to drahn@ otto@ and deraadt@ for feedback and help testing. Upgrade procedure if you don't want to use the damn snapshots: - build and install new kernel, reboot off it - build new gcc, do not install it yet - make includes - install new gcc - build and install lib/csu and lib/libc - make build | |||
2007-02-28 | do not bother printing 5 lines of cpu information which is always, on | Theo de Raadt | |
every machine, exactly the same. only print the most interesting bits ok miod, tested martin | |||
2007-02-26 | Zero rval[1] in setregs. | Miod Vallat | |
2007-02-26 | FPU disabled bit on SH4 is not a ``must be zero'' bit, but userland shall not | Miod Vallat | |
be allowed to fiddle with it anyway. | |||
2007-02-26 | Fix spurious right brace in some decoders, and always print the hex value for | Miod Vallat | |
unrecognized opcodes. | |||
2007-02-19 | only make this interface available to the kernel for now, discussed witha | Theo de Raadt | |
rt and such; tested and ok miod drahn | |||
2007-02-11 | typo in comment | Martin Reindl | |
2007-02-06 | Define trap #0x81 for cache range flush, will be necessary soon for gcc | Miod Vallat | |
trampoline code and ld.so. | |||
2007-02-06 | Use uvm_grow() instead of rolling our own inline version. | Miod Vallat | |
2007-02-06 | Add machine/atomic.h to all architectures and define two operations | Artur Grabowski | |
right now that are supposed to be atomic with respect to interrupts and SMP: atomic_setbits_int and atomic_clearbits_int. All architectures other than i386 and amd64 get dummy implementations since at first we'll be replacing operations that are done with "a |= bit" and "a &= ~bit" today. More proper implementations will follow kettenis@, miod@ ok | |||
2007-01-15 | power(4) driver for the power switch on many landisk models, hooked | Martin Reindl | |
up to machdep.kbdreset; modelled after the sparc64 power(4) driver discussed with miod@ and jsg@ | |||
2006-12-14 | Make pci subsystem aware of domains. Each host bridge gets assigned a unique | Mark Kettenis | |
domain number such that we can distinguish between busses with the same bus number that are behind different host bridges. Domains can be accessed by using different device nodes. ok deraadt@ |
