| 2008-01-15 | Revert r1.15 and flush pages (if cached) in pmap_remove_pv on every invocation, | Miod Vallat | |
| instead of when removing the last page. It looked correct, but is defeated by ``index'' cache invalidates. | |||
| 2007-12-18 | add power(4), a driver for the power button found on SGI O2's. | Jasper Lievisse Adriaanse | |
| when machdep.kbdreset is set, and the correct interrupt is fired, the machine gets shut down. with help from and ok jsing@, ok miod@ | |||
| 2007-12-18 | Expose the clock address space so that it can be used outside of clock(4). | Joel Sing | |
| ok miod@ | |||
| 2007-12-14 | Store the ARCBIOS ConsoleOut environment variable so that we can refer to | Joel Sing | |
| it later on. ok miod@ | |||
| 2007-11-25 | spelling fixes, from Martynas Venckus; | Jason McIntyre | |
| 2007-11-24 | Recognize the wait r5k instruction in ddb and use it in cpu_idle_cycle. | Miod Vallat | |
| ok jsing@ a while ago (and this diff is much much older) | |||
| 2007-10-25 | Be sure to enable interrupts on return from ddb if they were enabled before | Miod Vallat | |
| the break. | |||
| 2007-10-24 | pipleine -> pipeline | Miod Vallat | |
| 2007-10-24 | In cpu_switchto(), load pmap->pm_tlbpid manually, instead of expecting | Miod Vallat | |
| pmap_update() to return with this value in v0. A void function. Bwahahaha. | |||
| 2007-10-22 | stoped -> stopped | Joel Sing | |
| ok miod@ | |||
| 2007-10-18 | Make sure interrupts are really enabled at the beginning of proc_trampoline, | Miod Vallat | |
| tested by deraadt@ jsing@ | |||
| 2007-10-18 | No need to include <machine/pte.h> here. | Miod Vallat | |
| 2007-10-18 | Get rid of the silly union for mips pte. No functional change except | Miod Vallat | |
| pmap.h now includes pte.h. | |||
| 2007-10-14 | registred -> registered | Miod Vallat | |
| 2007-10-13 | There is no need to fiddle with spl in cpu_idle_{enter,leave}, actually. | Miod Vallat | |
| 2007-10-13 | Do not splhigh() before invoking sched_exit(), sched_exit() will do it better. | Miod Vallat | |
| 2007-10-10 | Make context switching much more MI: | Artur Grabowski | |
| - Move the functionality of choosing a process from cpu_switch into a much simpler function: cpu_switchto. Instead of having the locore code walk the run queues, let the MI code choose the process we want to run and only implement the context switching itself in MD code. - Let MD context switching run without worrying about spls or locks. - Instead of having the idle loop implemented with special contexts in MD code, implement one idle proc for each cpu. make the idle loop MI with MD hooks. - Change the proc lists from the old style vax queues to TAILQs. - Change the sleep queue from vax queues to TAILQs. This makes wakeup() go from O(n^2) to O(n) there will be some MD fallout, but it will be fixed shortly. There's also a few cleanups to be done after this. deraadt@, kettenis@ ok | |||
| 2007-09-22 | M_ZERO -> bzero. | Kenneth R Westerback | |
| ok art@ | |||
| 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. | |||
| 2007-09-03 | call savectx() in cpu_fork(), so that the new process can take signals | Miod Vallat | |
| correctly in child_return()'s userret(); makes the sys/kern/signal/earlysig regression test pass. From a 2.5 years old diff I should have commited much earlier. | |||
| 2007-09-03 | Typos from miod. 'requiered' -> 'required' in some comments. | Kenneth R Westerback | |
| 2007-07-18 | Prefer ``hit'' cache operations when flushing kernel memory. | Miod Vallat | |
| 2007-07-18 | bus_dmamem_map() maps with a single segment in directly-translated XKPHYS | Miod Vallat | |
| space, either cache coherent for regular mappings and uncached for BUS_DMA_COHERENT mappings, as done on all other platforms with direct mappings. | |||
| 2007-07-16 | Replace bunches of nops with the ITLBNOPFIX macro, which generates fewer | Miod Vallat | |
| nops unless we compile for early RM7000 flavours, which we usually don't do. | |||
| 2007-07-16 | On exit from switch_exit(), do not bother saving context and immediately | Miod Vallat | |
| jump into the scheduler loop. | |||
| 2007-07-16 | Do not reenabled interrupts when processing a ddb trap, for bad things may | Miod Vallat | |
| happen; from NetBSD | |||
| 2007-07-16 | Change idle_mask to be made of the cop0 SR bits unshifted and the cop0 IC bits | Miod Vallat | |
| shifted, instead of the other way around; this shaves a few instructions. | |||
| 2007-07-05 | Compute the correct address and try and print a matching symbol for j and | Miod Vallat | |
| jal instructions. | |||
| 2007-07-01 | In cpu_switch(), store the saved cpl in the pcb as a 64 bit store, so that | Miod Vallat | |
| the high order bits are not undefined when invoking hw_setintrmask() on return. | |||
| 2007-06-21 | Extent sgi bus_dma to cope with different views of memory: non-contiguous | Miod Vallat | |
| for the cpu, contiguous from different bases for devices. This allows memory above 256MB to be used with bus_dma (and we had really been lucky with the first few large-memory builds). Information about memory accesses taken from Linux. | |||
| 2007-06-20 | Do not hardcode imask[] size when intializing it. | Miod Vallat | |
| 2007-06-20 | In vunmapbuf(), explicitely remove mappings before invoking uvm_km_free(). | Miod Vallat | |
| Even if the latter would end up removing the mappings by itself, it would do so using pmap_remove() because phys_map is not intrsafe; but some platforms use pmap_kenter_pa() in vmapbuf(). By removing the mappings ourselves, we can ensure the remove function used matches the enter function which has been used. Discussed and theoretical ok art@ | |||
| 2007-06-20 | Protect pool operations with splvm. | Miod Vallat | |
| 2007-06-20 | Make sure IPL_CLOCK blocks device interrupts. | Miod Vallat | |
| 2007-06-18 | this is the sgi disklabel, mips64 is not the same | Theo de Raadt | |
| 2007-06-18 | this is the sgi disksubr, not some mythical "all mips64 architectures can ↵ | Theo de Raadt | |
| use it" balony | |||
| 2007-06-18 | Use a shorter form to load XKPHYS constants in .S code, shaves a few text | Miod Vallat | |
| bytes, no functional change. | |||
| 2007-06-18 | Disable instruction reordering around cpl assignments. | Miod Vallat | |
| 2007-06-18 | simplify error return case from writedisklabel() | Theo de Raadt | |
| 2007-06-17 | Eliminate a few straggling 'labelsector' field declarations from | Kenneth R Westerback | |
| cpu_disklabel's. 'labelsector' is not used anywhere according to grep. 'go for it' deraadt@ | |||
| 2007-06-17 | Coerce this into compiling. | Miod Vallat | |
| 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 | |||
| 2007-06-14 | Fix label name in writedisklabel(). | Miod Vallat | |
| 2007-06-14 | some spaces in the way | Theo de Raadt | |
| 2007-06-14 | excessive blank lines making the versions different | Theo de Raadt | |
| 2007-06-14 | set the prototype disklabel to version 1 | Theo de Raadt | |
| 2007-06-14 | do not depend on previous loop variable, use a constant instead | Theo de Raadt | |
| 2007-06-12 | all disksubr.c did their b_flags manipulation differently (and wrong). | Theo de Raadt | |
| correct and unify; ok thib miod | |||
| 2007-06-09 | The differences in the last non-homogeneous bounds_check_with_label() | Kenneth R Westerback | |
| routines (alpha, vax) prove to be not worth keeping. Move bounds_check_with_label() into the MI world. Eliminate unreliable and almost certainly useless checks for overwriting a disklabel. After discussion with deraadt@ | |||
| 2007-06-09 | unify DOSPTYP_FAT* code (some architectures missed a filesystem type or two) | Theo de Raadt | |
