them define __HAVE_PCIIDE_MACHDEP_COMPAT_INTR_ESTABLISH
in pci_machdep.h and pciide_map_compat_intr() only calls
pciide_machdep_compat_intr_establish() if that preprocessor
define exists.
Ports that don't need to do this no longer need to supply a
dummy function.
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
- for sizeof(void *) == 8 arch, this is mandatory. MHLEN is too small
already (less than 80) and there are chances for unwanted packet loss due
to m_pullup restriction.
- for other cases, the change should avoid allocating clusters in most cases
(even when you have IPv4 IPsec tunnel, or IPv6 with moderate amount of
extension header)
portmasters: if your arch chokes with the change (high memory usage or
whatever), please backout the change for your arch.
"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.
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.
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>.
