2013-01-02miod let one exec.c slideTheo de Raadt
2012-11-04Simplify Makefiles a bit, removing redundant stuff. ok espie@Matthieu Herrb
2012-10-17Document the 'boothowto hack' used to flag to (a few) DVACT_POWERDOWNTheo de Raadt
handlers how hard they should hit the hardware.
2012-10-08Revamp the sequences for suspend/hibernate -> resume so that the codeTheo de Raadt
paths are reflexive. It is now possible to fail part-way through a suspend sequence, and recover along the resume code path. Split DVACT_SUSPEND by adding a new DVACT_POWERDOWN method is used after hibernate (and suspend too) to finish the job. Some drivers must be converted at the same time to use this instead of shutdown hooks (the others will follow at a later time) ok kettenis mlarkin
2012-10-03Do not use <mips64/archtype.h> for loongson model numbers, but rather put theMiod Vallat
list in loongson's <machine/autoconf.h> directly. <mips64/archtype.h> is intended to be only used on ARCBios-like platforms.
2012-10-03Split ever-growing mips <machine/cpu.h> into what 99% of the kernel needs,Miod Vallat
which will remain in <machine/cpu.h>, and a new mips_cpu.h containing only the goriest md details, which are only of interest to a handful set of files; this is similar in spirit to what alpha does, but here <machine/cpu.h> does not include the new file.
2012-09-29Handle the coprocessor 0 cause and status registers as a 64 bit value now,Miod Vallat
as some odd mips designs need moro than 32 bits in there. This causes a lot of mechanical changes everywhere getsr() is used.
2012-09-29Kill the mostly unused VMTLB_xxx and VMNUM_xxx defines. Move all tlbMiod Vallat
knowledge to <machine/pte.h>. Add specific routines for tlb handling setup (at cpu initialization time) and tlb ASID wrap.
2012-09-29Proide a mips_sync() macro to wrap asm("sync"), and replace gazillions ofMiod Vallat
such statements with it.

2012-08-18glxpcib(4) invokes pcibattach assuming pcib doesn't need more than aMiod Vallat
`struct device' as its softc. This is not the case on loongson, and the glxpcib softc gets subtly corrupted, causing a kernel panic when attempting to select the glxpcib timecounter as the current timecounter. Skirt this by not using the pcib softc fields if we are invoked from glxpcib - it is not really worth putting pcib_softc in a header for the sake of MI glxpcib code.
2012-08-02remove leftover NOLINT, WANTLINT, LINTFLAGS, LOBJ vars and lint targets.Okan Demirmen
ok guenther@
2012-06-26create new machine/_float.h which is namespace clean. create a newTheo de Raadt
MI float.h which pulls in and defines the values that are needed from there, and repair sys/limits.h so that it defines the values it needs as well (depending on POSIX version, XPG version, etc). guenther has a more exact selection of that coming for limits.h. this also fixes a few mistakes for the vax. reviewed by kettenis and guenther.
2012-04-21Rework the signature of the cache handling routines again. It makes more senseMiod Vallat
to pass both the virtual and physical addresses of the page to clean to SyncDCachePage, which is the only routine using `Index' operations on the data cache, which might be virtually indexed at some levels but physically indexed at others. On the other hand, it does not make any sense to pass a physical address to routines using `Hit' operations (and they were discarding them anyway). In addition to making things cleaner, this fixes sporadic userland misbehaviour (read: SIGSGEV) on RM7000 O2 systems.
2012-03-26Add APM_IOC_HIBERNATETheo de Raadt
2012-03-25Move cache handling routines related definitions to a dedicated header file,Miod Vallat
rather than abusing <machine/cpu.h>.
2012-03-15uncached_base was introduced early in IP27 support, since these designs useMiod Vallat
subspaces in the CCA_NC uncached memory space. However, being coherent, there was never a need for bus_dma to use uncached addresses. This means that, on the only systems where uncached_base was not set to PHYS_TO_XKPHYS(0, CCA_NC), it was never used. Remove the variable, and replace PHYS_TO_UNCACHED() with PHYS_TO_XKPHYS(, CCA_NC). No functional change.
2012-03-03Fix the logic deciding whether to return PCI_COMMAND_MASTER_ENABLE in theMiod Vallat
emulated pci functions #2 and #3; from NetBSD
2011-11-08Garbage collect now unused MKDEP definitions. ok deraadt@Matthieu Herrb
2011-10-27Specify the TLS variant for each platform.Philip Guenthe
2011-10-10Introduce pci_probe_device_hook(pci_chipset_tag_t, struct pci_attach_args *).Miod Vallat
This mandatory function will get invoked in pci_probe_device(), and allows a pci host driver to alter the pci_attach_args passed to a device when attaching. This function will also, if returning non-zero, cause the device to be skipped completely during all the phases of the PCI device discovery (i.e. ressource enumeration, ressource assignment, and actual attachment). This particular feature is experimental and might be reverted in the future (or the scope narrowed to device attachment only). A dummy #define pci_probe_device_hook() 0 is added to all platforms except sgi, where real functions (currently only returning 0) are added; real meat will be added shortly. Discussed at s2k11, no objection from the usual suspects.

2011-07-21Support for the eBenton EBT-700 netbook, which is similar to the LemoteMiod Vallat
Yeeloong, but with a 7" display with a 800x480 resolution, and no webcam. There are still problems to get it booting from disk from PMON (colour me unsurprised), which are being looked at. Loading the boot blocks from a FAT USB stick, to then boot the kernel from the disk, is a reliable workaround in the meantime. Tested by Ban Keong Yee (bankeong dot yee on gmail) who is the ``lucky'' owner of such a machine, thanks for your time!
2011-07-08When reading dos labels use DOS_LABELSECTOR and don't use LABELOFFSET. For ↵Kenneth R Westerback
all these arch's LABELSECTOR == DOS_LABELSECTOR == 1, and LABELOFFSET == 0. Thus, to quote bob, "This is a no-op". Makes the expression used when writing label the same as the one used in readdoslabel().

2011-07-07The drahn memorial bad kernel build fix: prevent blood pressurePhilip Guenthe
spikes in other developers by making it so that removal of a .d file without removing the corresponding object will result in the latter being treated as out of date. ok beck@ art@ drahn@
2011-07-06On those archs that read their disk (vs iso/udf) disklabels exclusivelyKenneth R Westerback
via readdoslabel(), tweak writedisklabel() to write disklabels at the same place readdoslabel() reads them from. Irregardless of the physical disk sector size. As is done in i386/amd64 already. No change in behaviour for the 'normal' 512-byte sector case. ok deraadt@

2011-06-29Replace all instances of "scsibus* at hba?" with a single "scsibus* atMatthew Dempsky
scsi?" rule, similar to how ethernet PHY drivers attach at mii. Discussed on icb.
2011-06-26if_downall() cannot be done MI in sys_reboot() because vfs_shutdown()Theo de Raadt
might need network (ie. nfs). Move the call to the MD boot() routines. This cause for boot hangs diagnosed by kettenis.
2011-06-24machdep.kbdreset enables a shutdown by Ctrl-Alt-Del on amd64 andChristian Weisgerber
i386. Stop abusing it on other archs for controling a shutdown by pressing the soft power button: * Add a MI sysctl hw.allowpowerdown; if set to 1 (the default) it allows a power button shutdown. * Make acpi(4)/acpibtn(4) honor hw.allowpowerdown. * Switch the various power button intercepts on landisk, sgi, sparc64 and zaurus over to hw.allowpowerdown. * Garbage collect the machdep.kbdreset sysctl on all archs other than amd64 and i386. ok miod@
2011-06-23Fix the error path in bus_dmamem_map.Ariane van der Steldt
As discussed on icb: remove the comment, remove pmap_remove (uvm_km_free does that for us). ok oga@, deraadt@
2011-06-05Move the bufcachepercent setting code to MI locations -- set it to 42%Theo de Raadt
for now; that is unlikely to hit some of the remaining starvation bugs. Repair the bufpages calculation too; i386 was doing it ahead of time (incorrectly) and then re-calculating it. ok thib
2011-05-30Remove the freelist member from vm_physsegOwain Ainsworth
The new world order of pmemrange makes this data completely redundant (being dealt with by the pmemrange constraints instead). Remove all code that messes with the freelist. While touching every caller of uvm_page_physload() anyway, add the flags argument to all callers (all but one is 0 and that one already used PHYSLOAD_DEVICE) and remove the macro magic to allow callers to continue without it. Should shrink the code a bit, as well. matthew@ pointed out some mistakes i'd made. ``freelist death, I like. Ok.' ariane@ `I agree with the general direction, go ahead and i'll fix any fallout shortly'' miod@ (68k 88k and vax i could not check would build)
2011-05-25Set UX and SX in the system register early in boot. While not necessary onMiod Vallat
the real hardware, some emulators (such as those which name start with `qe' and end in `mu' and are four letters long) expect the cpu behaviour to honour the value of these bits. This is not worth doing but it's cheap.

2011-05-24On OpenBSD, we've always attached scsibus(4) to umass(4), even forMatthew Dempsky
ATAPI devices. atapiscsi(4) is only for handling ATAPI devices on an ATA bus, so umass(4) shouldn't care about it. ok krw@, dlg@; no objections from deraadt@
