thorpej bf2dcec4f5 Remove the use of splimp() from the NetBSD kernel. splnet() 
and only splnet() is allowed for the protection of data structures
used by network devices.

leo 8507fcec54 Update these for Milan addresses. 2001-04-12 07:17:30 +00:00
leo 3f7694f804 Adapt these for use on the Milan. 2001-04-11 14:45:07 +00:00
leo 247d880fc9 The Milan uses the U0 pin to switch the pci-bridge between little & big 
endian mode. That's why I moved the 'wired' flag to U1.
 2001-04-10 19:51:00 +00:00
leo b44e732ff6 Expand bus_dma implementation. It will now handle the bounce buffer 
extensions needed to make the isa floppy driver on the Milan work.
 2001-03-09 20:55:46 +00:00
thorpej 2c4c690f14 Add the BUS_DMA_STREAMING flag. 2001-03-07 22:42:16 +00:00
thorpej d85a75f583 Make sure everybody has an splvm() and equate it with splimp() (splimp() 
is the historical name for this interrupt level, and the historical name
is going to go away in the near future).
 2001-01-14 02:00:37 +00:00
leo c21ca4d86a Add the Milan as a possible machine type. 2001-01-07 21:08:03 +00:00
leo 3c48826086 Make ahdi_part and ahdi_root 'packed' so I can use this include file on 
an x86 machine to analyze my atari disk.

sommerfeld 851de295eb Change pci_intr_map to get interrupt source information from a "struct 
pci_attach_args *" instead of from four separate parameters which in
all cases were extracted from the same "struct pci_attach_args".

This both simplifies the driver api, and allows for alternate PCI
interrupt mapping schemes, such as one using the tables described in
the Intel Multiprocessor Spec which describe interrupt wirings for
devices behind pci-pci bridges based on the device's location rather
the bridge's location.

Tested on alpha and i386; welcome to 1.5Q

scw 4350a7f2b7 Unification of the m68k syscall() function. 2000-12-19 21:09:54 +00:00
thorpej e6da7eebba We use 8K pages on the Atari. Make PAGE_SIZE and friends into 
compile-time constants.
 2000-11-14 19:01:09 +00:00
leo 716d4c3866 Do not pull-in machine/intr.h when _KERNEL is not defined. This fixes 
compilation problems in the regression tests.
 2000-11-01 12:08:16 +00:00
leo ec2e9cd4c8 Add PCB_REGS_* defines. This makes ddb compile again. 2000-09-30 20:36:40 +00:00
is 2c86369fc4 The Atari pmap does wired page accounting; advertize it to UVM. 2000-09-28 09:09:28 +00:00
thorpej 4db6fc7542 Make need_resched() take a "struct cpu_info *" argument. This 
causes gives a primitive form of processor affinity.  Its use in
roundrobin() still needs some work.
 2000-08-25 01:04:06 +00:00
thorpej 58e7a6954b Add spllock(). See spl(9) for details. 2000-08-22 19:46:26 +00:00
kleink e695f72a2e Add <machine/int_types.h>, which provides namespace-pure definitions 
of exact-width integer types.
 2000-06-26 15:42:16 +00:00
simonb 889c658b5b Change the kernel mmap interface so that the offset to map is an 
"off_t" and the return value is a "paddr_t" to allow mappings
at offsets past 2^31 bytes.  Somewhat inspired by FreeBSD, which
only changed the offset to a "vm_offset_t".

Includes updates for the i386, pc532 and sh3 mmmmap from Jason Thorpe.
 2000-06-26 04:55:19 +00:00
cgd cffb580806 Implement the more flexiable `evcnt' interface as discussed (briefly) on 
tech-kern and now documented in evcnt(9).
 2000-06-04 19:14:14 +00:00
cgd 47449a63d2 kill __P in these files. (I had to look at them anyway with an eye for 
adding some protos... and adding them with __P seems wrong, but mixing
__P and not __P in the same file seems wrong too, so...)

thorpej a7d0570e67 First sweep at scheduler state cleanup. Collect MI scheduler 
state into global and per-CPU scheduler state:

	- Global state: sched_qs (run queues), sched_whichqs (bitmap
	  of non-empty run queues), sched_slpque (sleep queues).
	  NOTE: These may collectively move into a struct schedstate
	  at some point in the future.

	- Per-CPU state, struct schedstate_percpu: spc_runtime
	  (time process on this CPU started running), spc_flags
	  (replaces struct proc's p_schedflags), and
	  spc_curpriority (usrpri of processes on this CPU).

	- Every platform must now supply a struct cpu_info and
	  a curcpu() macro.  Simplify existing cpu_info declarations
	  where appropriate.

	- All references to per-CPU scheduler state now made through
	  curcpu().  NOTE: this will likely be adjusted in the future
	  after further changes to struct proc are made.

Tested on i386 and Alpha.  Changes are mostly mechanical, but apologies
in advance if it doesn't compile on a particular platform.
 2000-05-26 21:19:19 +00:00
thorpej f51470a514 Require that each each MACHINE/MACHINE_ARCH supply a lock.h. This file 
contains the values __SIMPLELOCK_LOCKED and __SIMPLELOCK_UNLOCKED, which
replace the old SIMPLELOCK_LOCKED and SIMPLELOCK_UNLOCKED.  These files
are also required to supply inline functions __cpu_simple_lock(),
__cpu_simple_lock_try(), and __cpu_simple_unlock() if locking is to be
supported on that platform (i.e. if MULTIPROCESSOR is defined in the
_KERNEL case).  Change these functions to take an int * (&alp->lock_data)
rather than the struct simplelock * itself.

These changes make it possible for userland to use the locking primitives
by including <machine/lock.h>.

leo 7d08f8e623 Add dummies for barrier methods (copied from i386). 2000-04-11 07:12:47 +00:00
tron e86957458a Install "machineendian_machdep.h". 2000-03-17 22:36:31 +00:00
mycroft 9e21b6555a In the `MY THAT'S GROSS' department... 
Eliminate the recursive include of machine/endian.h from sys/endian.h.
 2000-03-17 00:09:18 +00:00
thorpej dded044fc2 Update for the NKMEMPAGES changes. 2000-02-11 19:25:12 +00:00
thorpej 52a2804a5c Add a new function call to the ISA DMA API: isa_dmamaxsize(), which returns 
the maximum transfer size for the specified DMA channel.  Make all clients
of ISA DMA use this call to determine their maximum transfer size.
 2000-02-07 22:07:27 +00:00
jdc be5d89da1a Add definition for default swap partition (libahdi uses this). 2000-02-05 21:14:55 +00:00
cgd 7d16ac338c add __BROKEN_CONFIG_UNIT_USAGE #define, becuase these ports do very 
wrong things with device configuration data "cf_unit" information.
 2000-02-05 00:13:22 +00:00
tsutsui b0fbaa33fb Remove obsoleted macros. 2000-01-26 09:44:10 +00:00
drochner 8eb798e603 define a "BUS_SPACE_MAP_PREFETCHABLE" flag which basically means that 
device accesses are idempotent (but should not be cached by the CPU)
 2000-01-25 22:13:17 +00:00
leo 4911054546 Allow storage-space to be passed to the alloc_bus_space_tag() functions. This 
permits static tags to be used during early console init.
 2000-01-19 13:12:54 +00:00
leo a93741b5c7 Determine the default floppy type on the TT/Falcon by reading the config 
switches. (Thanks to Michael Schwingen for the missing bits of information!).
 2000-01-06 12:14:33 +00:00
kleink 11e6c54cfc C99: Define a NAN macro in <math.h> which evaulates to a constant expression of 
a single-precision quiet NaN; only to be defined on platforms that do support
this value.
 1999-12-23 10:15:05 +00:00
leo ef4d7a827f Change the copy_region function to shutup gcc's unused warnings in some 
cases. Use the bus_space_tag without doing something useful... (idea from
Matthias Drochner).
 1999-12-13 15:40:28 +00:00
leo c9457413cb Implement an allocator for VA-space using fixed extent maps. It is now 
possible to allocate VA-space before uvm is initialized.
 1999-12-06 16:06:24 +00:00
ragge 0513268399 CL* discarding. 1999-12-04 21:13:19 +00:00
kleink 1c2019b5a8 Rip protection against multiple inclusion from wrapper headers. 1999-11-09 21:34:03 +00:00
leo 4c4e4258e2 Use extent maps. 1999-10-28 13:38:35 +00:00
leo 64f9129eff Add prototype of isa_intr_alloc(). 1999-10-21 15:32:08 +00:00
leo 313488aee7 Reverse the order in which PCI cards are scanned. Now the order matches the 
TOS-scan order. This causes TOS & NetBSD to use the same video card on
a system with multiple VGA cards.
 1999-09-22 07:15:43 +00:00
mycroft c3e1f6741d A foolish consistency. 1999-08-30 18:58:01 +00:00
simonb 06a92524c2 Include <sys/bswap.h> for function prototypes. i386, pc532 and vax 
still include <machine/byte_swap.h> and define macros for some of
the bswap*() functions.
 1999-08-21 05:39:51 +00:00
leo d7601eb1b1 Correct the argument order for memcpy(). This tremendously improves the 
behaviour of wscons.... (Why did history create both bcopy & memcpy?)
