fvdl a5e7e03043 Use fixed mode, not lopri, for delivering IO interrupts. Suggested by 
Peter O'Kane. Fixes interrupt problems on some Xeon systems.

nathanw bb630a5378 Add PSL_T to PSL_USER; it's fine for a program to want to trap itself. 2004-11-30 22:41:57 +00:00
ws 739e2052fd We just checked that the parent is the root, not current. 
So we better determine the bus number of this parent node.
Now, MPACPI on my Opteron board finally correctly determines its
PCI/AGP busses even without the help of the AMD64 Address Map
support implemented in my local tree.

yamt d82d2638a7 __cpu_simple_lock: loop without locking cache or asserting LOCK#. 2004-10-23 21:25:22 +00:00
yamt fa29ea9740 to determine if an interrupt needs to grab the kernel lock or not, 
check interrupt's own ipl rather than cpu's current ipl.

thorpej f9403749b7 Use the new BTINFO_BOOTWEDGE bootinfo to discover the booted disk and 
wedge.
 2004-10-23 17:20:59 +00:00
thorpej 0798da74ba Add support for passing booted wedge information to the kernel. 2004-10-23 17:20:04 +00:00
thorpej 42b8fac3b8 Move boot device detection code from i386 and amd64 ports to x86_autoconf.c. 
Rename i386_alldisks and x86_64_alldisks to x86_alldisks, adjust other
references to compensate.

drochner 46289e1fef Phase out the use of a string as first "attach args" member to control 
which bustype should be attached with a specific call to config_found()
(from a "mainbus" or a bus bridge).
Do it for isa/eisa/mca and pci/agp for now. These buses all attach to
an mi interface attribute "isabus", "eisabus" etc., and the autoconf
framework now allows to specify an interface attribute on config_found()
and config_search(), which limits the search of matching config data
to these which attach to that specific attribute.
So we basically have to call config_found_ia(..., "foobus", ...) where
such a bus is attached.
As a consequence, where a "mainbus" or alike also attaches other
devices (eg CPUs) which do not attach to a specific attribute yet,
we need at least pass an attribute name (different from "foobus") so
that the foo bus is not found at these places. This made some minor
changes necessary which are not obviously related to the mentioned buses.

fvdl e8af4bc978 Keep ioapic in the correct order in the global linked list that stores 
them. Fixes cases where the ACPI SCI int has to be guessed, because there
are multiple ioapics in the system.

put back the copyright from there.

kochi d23b9803c9 fix a duplicate member in designated initializers, which was a bug 
introduced in rev 1.5.
pointed out by Andreas Gustafsson.

fvdl 029ca90566 Updaing ci_ilevel and testing ci_ipending must be done with all interrupts 
off, or priority inversion can occur, which can lead to IPI deadlocks.
Leaves interrupts off for a bit longer, sadly, but with no noticeable
effects on the systems I tested on.

From YAMAMOTO Takashi.

yamt 4af17d9901 simplify x86 bus_dma implementation. 
(rather than passing &lastaddr and &seg around,
use and update bus_dmamap_t directly.)
 2004-06-12 17:16:44 +00:00
yamt e25482312e - introduce _bus_dmamap_load_paddr, which takes (paddr, size) and 
add the range to the map, and use it for _bus_dmamap_load_{buffer,mbuf}.
- _bus_dmamap_load_mbuf: in the case of M_EXT_PAGES, deal with vm_pages
  directly rather than doing pmap_extract on given kva.

as a side effect, do a segment coalescing and boundary checks for mbufs.

ok'ed by Frank van der Linden and Jason Thorpe on tech-kern@.

yamt 0238f7233c simplify x86 bus_dma internal "load" functions.

yamt 1b31a2b6a0 - introduce a function, i82489_icr_wait, which waits for
