fvdl ab3d5bdcea Catch up with the new acpica code. 2003-10-31 20:56:55 +00:00
fvdl 7d342b5852 * keep track of PCI buses that aren't known by firmware, but are found
by NetBSD
* use this info in in intr_find_mpmapping
* get rid of the last argument to intr_find_mpmapping, it was redundant

mycroft e24c0c7dfc Move a panic() to a different location, and eliminate a bogus initializer. 2003-10-29 03:40:56 +00:00
mycroft f6f24ead9c In _bus_dma_uiomove():
* Don't punt after the first iov in the UIO_SYSSPACE case.  Not that this ever
  happens in practice right now.
* If we get through the loop, error==0 by definition, so just return 0.
* Eliminate bogus initializer.

kleink 422697679e * Move the definitions for types other than single-precision and double-
precision back to machine-dependent headers.  C99 has no strict
  requirement which, if any, extended-precision type `long double' must
  match, and even between 80-bit formats there are differences in
  implementation (m68k vs. x86).
* On arm, consider __VFP_FP__.

fvdl e74e8c0c71 Correctly walk up the PCI bus tree to find an interrupt match with
a swizzled pin.
2003-10-21 23:25:48 +00:00
fvdl 80cec054e5 If a bus has not been configured by MPBIOS/ACPI, and the attach hook
for it is called, mark it as configured.
2003-10-21 23:22:52 +00:00
fvdl 6a6db3cbd9 Add hooks and structures to allow the MP table intr mapping code a
better shot at finding a mapping. For PCI interrupts, if a bus
has no mappings, try its parent, with the swizzled pin, and the
bridge's device number.

tron 676596e33a Fix build problem when MPACPI is used without ioapic as proposed by

fvdl 0a79ef3086 Allow probing of CPUs only by ACPI, so that MPBIOS can still do interrupt
mapping should ACPI have a quirk. From Christos. One change by me: make
sure that lapic_boot_init doesn't get called twice, otherwise the
cpu_info entry for the CPU with id 0 gets zapped.

lukem 1c33b4e6a4 Overhaul MBR handling (part 1):
<sys/bootblock.h>:
    *	Added definitions for the Master Boot Record (MBR) used by
	a variety of systems (primarily i386), including the format
	of the BIOS Parameter Block (BPB).
	This information was cribbed from a variety of sources
	including <sys/disklabel_mbr.h> which this is a superset of.

	As part of this, some data structure elements and #defines
	were renamed to be more "namespace friendly" and consistent
	with other bootblocks and MBR documentation.
	Update all uses of the old names to the new names.

<sys/disklabel_mbr.h>:
    *	Deprecated in favor of <sys/bootblock.h> (the latter is more
	"host tool" friendly).

amd64 & i386:
    *	Renamed /usr/mdec/bootxx_dosfs to /usr/mdec/bootxx_msdos, to
	be consistent with the naming convention of the msdosfs tools.

    *	Removed /usr/mdec/bootxx_ufs, as it's equivalent to bootxx_ffsv1
	and it's confusing to have two functionally equivalent bootblocks,
	especially given that "ufs" has multiple meanings (it could be
	a synonym for "ffs", or the group of ffs/lfs/ext2fs file systems).

    *	Rework pbr.S (the first sector of bootxx_*):
	    +	Ensure that BPB (bytes 11..89) and the partition table
		(bytes 446..509) do not contain code.
	    +	Add support for booting from FAT partitions if BOOT_FROM_FAT
		is defined.  (Only set for bootxx_msdos).
	    +	Remove "dummy" partition 3; if people want to installboot(8)
		these to the start of the disk they can use fdisk(8) to
		create a real MBR partition table...
	    +	Compile with TERSE_ERROR so it fits because of the above.
		Whilst this is less user friendly, I feel it's important
		to have a valid partition table and BPB in the MBR/PBR.

    *	Renamed /usr/mdec/biosboot to /usr/mdec/boot, to be consistent
	with other platforms.

    *	Enable SUPPORT_DOSFS in /usr/mdec/boot (stage2), so that
    	we can boot off FAT partitions.

    *	Crank version of /usr/mdec/boot to 3.1, and fix some of the other
	entries in the version file.

installboot(8) (i386):
    *	Read the existing MBR of the filesystem and retain the BIOS
    	Parameter Block (BPB) in bytes 11..89 and the MBR partition
	table in bytes 446..509.  (Previously installboot(8) would
	trash those two sections of the MBR.)

mbrlabel(8):
    *	Use sys/lib/libkern/xlat_mbr_fstype.c instead of homegrown code
	to map the MBR partition type to the NetBSD disklabel type.


Test built "make release" for i386, and new bootblocks verified to work
(even off FAT!).

fvdl a7a118bf66 Backout previous for now, it breaks second CPU spinup. It'll be back later. 2003-10-07 21:47:57 +00:00
fvdl 9771ccbb32 Changes from Christos to fall back to MPBIOS for interrupt probing
if MPACPI fails, so that MPACPI can be used to only probe CPUs
if needed.

nathanw 4d59420344 Move __cpu_simple_lock_t and __SIMPLELOCK_{UN,}LOCKED to machine/types.h
so that they can be used in a namespace-friendly way.

skd 3736d609a5 Fix for ioapic irq routing. This fixes kern/22728.
Approved by fvdl.
2003-09-18 19:31:19 +00:00
fvdl 5a759ef06c Move the bulk of pci_intr_string into a seperate intr_string function. Use
that new function to print the pciide compat interrupt in pciide_machdep.c.
Share pciide_machdep.c between amd64 and i386.
2003-09-06 17:44:36 +00:00
fvdl 40b81ea5a1 If possible, put the device name of the APIC used into the interrupt string,
not "apic N". This makes it easier to match vmstat output with dmesg output.
2003-09-06 14:55:50 +00:00
fvdl 631d339e09 When establishing the ACPI SCI, make sure it's always active low (as well
as level-triggered). Do this by changing the MP config entry that was
set up for the interrupt. Do not change anything if there was an ACPI
interrupt source override, assume that this contains the correct
information already.

itojun ffb2df7cd0 variable 'sc' needed in MPACPI case (what should we do about NIOAPIC?) 2003-08-27 11:38:54 +00:00
fvdl c43b35423e Pass pointers to frames from assembly, do not use the 'frame on stack
as argument passed by value' trick, as gcc 3.3.x makes (valid) assumptions
about the stack that will not be true. Costs 2 instructions per trap/syscall
on i386, 4 per interrupt for MP. One instruction per trap/syscall on amd64,
2 per interrupt for MP. I expect gcc 3.3.1 to make up for this by better
optimization (it'd better..)

While here, make amd64 compile again by using subr_mbr_disk.c

fvdl d5aece61d6 Back out the lwp/ktrace changes. They contained a lot of colateral damage,
and need to be examined and discussed more.
2003-06-29 22:28:00 +00:00
darrenr 960df3c8d1 Pass lwp pointers throughtout the kernel, as required, so that the lwpid can
be inserted into ktrace records.  The general change has been to replace
"struct proc *" with "struct lwp *" in various function prototypes, pass
the lwp through and use l_proc to get the process pointer when needed.

Bump the kernel rev up to 1.6V

thorpej 452a8fdae2 Rename IPL_IMP -> IPL_VM. 2003-06-16 20:00:56 +00:00
fvdl 7dd7f8baa2 Handle 64bit DMA addresses on PCI for platforms that can (currently only
enabled on amd64). Add a dmat64 field to various PCI attach structures,
and pass it down where needed. Implement a simple new function called
pci_dma64_available(pa) to test if 64bit DMA addresses may be used.
This returns 1 iff _PCI_HAVE_DMA64 is defined in <machine/pci_machdep.h>,
and there is more than 4G of memory.
2003-06-15 23:08:53 +00:00
thorpej 0eff671820 Also pass a type argument to comcnattach() and com_kgdb_attach().
comspeed() (and thus cominit()) may need this information.
