2010-07-03Intel 3400 Thermal Sensor driver, found on some new Intel machines.Mike Larkin
This is also the same as the Intel Series 5 Thermal Sensor. ok deraadt@, kettenis@
2010-07-02remove unused pciaddr_search function.Jonathan Gray
ok kettenis@
2010-07-02usefull -> useful;Jason McIntyre
2010-07-02m_copyback can fail to allocate memory, but is a void fucntion so gymnasticsBret Lambert
are required to detect that. Change the function to take a wait argument (used in nfs server, but M_NOWAIT everywhere else for now) and to return an error ok claudio@ henning@ krw@
2010-07-02initialize values to something sensible.Ted Unangst
ok deraadt pirofti
2010-07-02Add ability to limit memory presented to kernel withTobias Weingartner
'machine memory =128M' style commands. Thanks to phessler for finding a small man page niggle. Bumped version strings to a nice round fraction, and make them the same across the board. Easier to identify boot binary versions that way. ok thib@, tedu@, phessler@
2010-07-01Make our trapframe squeeky clean in setregs(). Avoid leaking registers intoMark Kettenis
the new process image. ok deraadt@, guenther@
2010-07-01Synch instead of flush FPU state on APs before suspending.Mike Larkin
tested by kettenis@ on i386 and myself on amd64 ok kettenis@
2010-07-01I accidentally whacked something important. Sorry.Ted Unangst
2010-07-01another day, another compat gets removed. today is ibcs2's turnTed Unangst
2010-07-01Backout recent AML changes, breaks on R210 and othersJordan Hargrave
2010-07-01mark acpi_savecpu with the gcc returns_twice attribute as suggestedJonathan Gray
by deraadt so the stack will be sane during suspend/resume with gcc4. Noticed on i386 due to the lack of general purpose registers compared to amd64. ok deraadt@ mlarkin@
2010-07-01Add a look-up table for machines that have special vga cards. This table willPaul Irofti
tell, based on vendor/product/subvendor/subproduct ids, how the video reposting should be done: via the emulator or the bios video call in locore. The default is to do none of those, which is how most machines work. Okay kettenis@, deraadt@.
2010-07-01More accurate comment as to what happens with acpi_savecpuMike Larkin

2010-06-28Ah, this will not help the netboot caseTheo de Raadt
2010-06-27Disable uguru(4). Its probe touches an address used by something else on theMark Kettenis
Dell r815, which causes all sorts of nasty effects like instant reboots, NMIs and PCI BARs being set to zero. ok dlg@
2010-06-27Mark the PXE boot device as "netboot" even if we do not containTheo de Raadt
nfs client support (yes, it becomes the root device too, but for ramdisks this is OK because they are not a swap generic configuration) Discussion with reyk and halex
2010-06-27If you include <uvm/uvm.h>, you do not need to include any other <uvm/uvm_foo.h>Miod Vallat
2010-06-27Add the TPOFF* and DTP{MOD,OFF}* definitions that ld.so will need forPhilip Guenthe
doing thread-local storage and fix a typo in one that was already defined. ok kettenis@ drahn@
2010-06-27uvm constraints. Add two mandatory MD symbols, uvm_md_constraintsThordur I. Bjornsson
which contains the constraints for DMA/memory allocation for each architecture, and dma_constraints which contains the range of addresses that are dma accessable by the system. This is based on ariane@'s physcontig diff, with lots of bugfixes and additions the following additions by my self: Introduce a new function pool_set_constraints() which sets the address range for which we allocate pages for the pool from, this is now used for the mbuf/mbuf cluster pools to keep them dma accessible. The !direct archs no longer stuff pages into the kernel object in uvm_km_getpage_pla but rather do a pmap_extract() in uvm_km_putpages. Tested heavily by my self on i386, amd64 and sparc64. Some tests on alpha and SGI. "commit it" beck, art, oga, deraadt "i like the diff" deraadt
2010-06-26Don't #include <sys/user.h> into files that don't need the stuffPhilip Guenthe
it defines. In some cases, this means pulling in uvm.h or pcb.h instead, but most of the inclusions were just noise. Tested on alpha, amd64, armish, hppa, i386, macpcc, sgi, sparc64, and vax, mostly by krw and naddy. ok krw@
2010-06-26Don't try to halt an AP if holding sched_lock since that causes hangsMike Larkin
on resume. Fail early if this is detected, so that we have a chance to catch it. ok kettenis@, deraadt@

ok dlg@
2010-06-10Declare safepri at the MD level on each platform, so that the kern_synch.cTheo de Raadt
does not have to deal with it as a common. Some platforms may be missed by this commit... if you spot one, fix it the same way. ok miod

ok deraadt@
2010-06-08in viac3_crypto_setup(), if we fail to get a crypto driverid,Thordur I. Bjornsson
free the softc before we return. While here, make the allocation code a bit prettier too. OK deraadt@
2010-06-04Don't warn about not knowing what the bus clock is on core i7/i5/i3Jonathan Gray
as the high/low guessing won't be done on these processors due to MSR differences.
2010-06-01use --warn-common for linking (some arch's will show new warnings), andTheo de Raadt
prefer binutils-compatible options in STRIPFLAGS (now that our non-binutils strip(1) can handle them too) ok drahn; miod kettenis (for parts)
2010-05-31Completely rewrite the tags file creation process. use config(8) againstTheo de Raadt
a fat kernel (GERERIC or GENERIC.MP) into a temporary dir, then extract some variables using make -V, and after some more singing and dancing use this full and (more) correct list of files with ctags. Don't read this code. ok guenther
2010-05-28${PARAM} is now included in ${CPPFLAGS}, so stop passing it separatelyPhilip Guenthe
to genassym.sh ok deraadt
2010-05-25The _arch and _mach variables now come from config(8), decreasing even furtherTheo de Raadt
the differences between these files. You will need a newer config(8) binary to be able to build kernels. ok kettenis miod
2010-05-25Hand-list the two-step assym.h -> .[Ss] -> .o dependencies. TheTheo de Raadt
result: kernels built without 'make depend'-provided information (ie. the .depend file) are more likely to have their *.[Ss] file compilations track changes to *.h files. The "*.o: assym.h" dependencies listed are gotten from reading the .depend output --- from the biggest kernel possible (ie. GENERIC.MP). When an architecture changes in a substantial way (new .[sS] files), the list should be updated in the prettiest way possible. This is not encouraging people to skip 'make depend'; other issues are not resolved and may be solved later with a change guenther is working on. You can still screwed really easily, so continue running make depend as config tells you. Idea from a discussion with drahn ok drahn, kettenis likes the idea too
2010-05-25${SRCS} is only used once, and fits onto the line where it is usedTheo de Raadt
idea that came out of discussion with drahn
2010-05-24give up on -Wvariable-declTheo de Raadt
delete the archaic links: target which is easily misused handle special .[sS] files in a portable way
2010-05-24Remove PHYs which don't have an associated driverJonathan Gray
on the ramdisks. ok deraadt@
2010-05-24Unify the dependency time check for whether an architecture has SFILESTheo de Raadt
2010-05-24stupid typo snuck inTheo de Raadt
2010-05-24Reduce differences between the Makefile.* files for all architectures.Theo de Raadt
ok various people, tested by fewer people, tested by me on 15.
2010-05-23seteconf() died years agoTheo de Raadt
2010-05-23no need for -D__i386__ since it is supplied by the compiler.Theo de Raadt
Also move towards passing $PARAM around in CPPFLAGS, instead of compiling param.c in a special way, as discussed with miod
2010-05-22protection should use the upper case namesTheo de Raadt
2010-05-10Continue with the horrible habit of using agp_machdep.c for agp related MDOwain Ainsworth
things that there really isn't a decent api for elsewhere. Since on recent intel IGPs the gtt aperture is too big (256meg is not uncommon) to be mapped on a kva-constrained arch like i386, introduce an agp mapping api that does things depending on arch. On amd64 which can afford the space (and will use the direct mapping again soon)just do bus_space_map() on init, then parcels things out using bus_space_subregion(), thus avoiding map/unmap overhead on every call (this is how inteldrm does things right now). On i386, we do bus_space_map() and bus_space_unmap as appropriate. Linux has some tricks here involving ``atomic'' maps that are on only one cpu and that you may not sleep with to avoid the ipi overhead for tlb flushing. For now we don't go down that route but it is being considered. I am also considering if it is worth abstracting this a little more, improving the api and making it a general MD interface. Tested by myself on i386 and amd64 and by drahn@ (who has one of the machines with an aperture that is too big) on i386.
2010-05-09Make i386 use a pointer to the trap frame like everybody else instead ofMark Kettenis
the weird "pass by reference" that causes problems with gcc4. ok nicm@, tom@
2010-05-08Page Attribute Tables (PAT) support for x86.Owain Ainsworth
PAT allows setting per-mapping cachability bits. Our main interest in it for write combining mappings so we do not have to rely so heaviliy on mtrrs (which are stupidly set up on more and more machines). MD flags to pmap allow setting these bits (which bus_space now uses for PREFETCHABLE maps), if a vm page has a bit set, then we will use WC for all mappings of a page (used for userland mappings). We also check for known errata and fall back to UC- mappings in that case. comments from kettenis@, tedu@ and william@. kettenis@, tedu@ ok.
2010-05-07fix packed use as pointed out by gcc4.Jonathan Gray
ok kettenis@
2010-05-02The Cyrix "coma bug" workaround code has a really convoluted way to write 0Mark Kettenis
into a magic register. Simplify the code by making this explicit, but keep the dummy read just in case this has a magic side-effect. And yes, as far as I can tell, writing 0 is really what was intended here. Makes gcc4 happy. No binary change with gcc3. ok jsg@
2010-04-30Right now, if anything internal changes with a uvm object, diverseOwain Ainsworth
places in the tree need to be touched to update the object initialisation with respect to that. So, make a function (uvm_initobj) that takes the refcount, object and pager ops and does this initialisation for us. This should save on maintainance in the future. looked good to fgs@. Tedu complained about the British spelling but OKed it anyway.
