DTrace: okay *really* fix the deadman exit handling.  No need for that
over-complicated handshake. Fixes a lockdebug mutex held issue.

(darran)

First part of shrinking/growing metadata partition support:

- extending the metadata partition

Still to follow:
- sparsify metadata partition
- growing the metadata partition
- unsparsifying metadata partition

(reinoud)

Merge if_wm.c rev. 1.162.4.13 and if_wmvar.h rev. 1.2.46.3 into maintrunk.
Increase the timeout value to prevent timeout on 80003. The values are taken
from Intel's e1000 driver. Tested by spz and me.

(msaitoh)

Convert to mdoc.

spotting this.

Use VM_PAGE_TO_MD().  Only compile tested.

(uebayasi)

Make the UP and MP ASID allocation algorithm common.  Significantly improve
the algorithm.  Now when we exhaust the ASIDs, interrogate the TLB for active
ASIDS and release all the other for future allocations.  This leaves the
TLB entries with ASIDs valid avoiding the need to re-incur TLB misses for
them.

(matt)

Add mipsXX_tlb_record_asids - records what ASIDs have valid TLB entries in
the TLB.
Move some mips3 specific routines from locore.S to locore_mips3.S

a very preliminary driver for Wildcat 5110 / Sun XVR-500 graphics boards
Since we don't have any documentationthis driver is unaccelerated and thanks

Don't mention cardbus_free_tag() and Cardbus_free_tag(), they are no

Cardbus_free_tag() and cardbus_free_tag() are no-ops, so get rid of them

(dyoung)

Update the doco, just in case somebody adds a new CardBus driver
before I've finished tucking CardBus under the PCI abstraction,
unlikely though that is.

(dyoung)

Start to tuck Cardbus under the PCI abstraction.  Step #1, textual
substitution: for all practical purposes, pcitag_t and cardbustag_t are
interchangeable, so just use pcitag_t.  Ditto pcireg_t and cardbusreg_t.

Poison new uses of cardbusreg_t and cardbustag_t by deleting the type

(dyoung)

Fix handling of 6bit VID register (6th bit takes place of 12VIn sensor).

Move VID out of sysctl tree - make it a separate sensor of type INTEGER.

Clean-up some of the chip-descriptors.

(pgoyette)

Use device_private().

(dyoung)

Use device_t, device_private().

(dyoung)

A pointer typedef entails trading too much flexibility to declare const
and non-const types, and the kernel uses both const and non-const
PMF qualifiers and device suspensors, so change the pmf_qual_t and
device_suspensor_t typedefs from "pointers to const" to non-pointer,
non-const types.

DTrace: Get the CTF tools building as part of the toolchain.

up some bugs!)

(dyoung)

Rename to 'pc' all variables 'pci_chipset_tag'.

Fix a bug in the dtrace_state_deadman() thread; return should have been

Fix a wrong calculation bug around RX ring buffer memory address
slipped in about sixteen years ago.  Fortunately, it had been working
for ages because some devices used address zero and other devices
ignored wrong higher bits.

Tested on we(4) (SMC Elite Ultra) and ne(4) (NE2000 compatible
named UL0001) on ISA.
Note FreeBSD also uses the same correct value in their ed(4) driver.

uvm_fault_upper_lookup, uvm_fault_upper_neighbor: There is no point to call
pmap_update() without calling pmap_enter().

- define tlb_flush_pte() in terms of sp_tlb_flush_pte() for the
  !MULTIPROCESSOR case

this centralises some CPU_IS_USIII_UP() tests.

(mrg)

Implement DIOCGPHYSADDR, a special block device ioctl for block devices that
can be directly memory-mapped.  When such a device is mounted, VFS checks
the backing store is XIP capable by querying this ioctl.

Add struct disk to struct flash_softc and let it do common bdev tasks.

When adding a CPU to a TLB, mark the kernel pmap as "active" and "onproc"

Fix bug because of typo: "if (foo); something" is not the

- Use ctob() instead of ptoa() to obtain physical addresses from frame
numbers. Using ptoa() will cast to vaddr_t, which might no be adequate
for architectures where sizeof(paddr_t) > sizeof(vaddr_t) (like i386 PAE).

- small fix inside AGP heuristics to avoid masking high order bits for
systems with more than 4GB.

Move ahci_channel_start() after BSY has cleared (what seems to matter

(bouyer)

Use correct offset to block number calculations.

Also change access to filesystem blocks to be done by fragment instead
of by physical block. Fragments are the fundamental blocks of the
filesystem.

For a theoretical filesystem that accesses the disk in smaller units
than stored in mp->mnt_fs_bshift, the assumption might be wrong. But
this will also break other subsystems. The value mp->mnt_dev_bshift
which formerly represents the physical sector size is currently only
virtual in NetBSD (always DEV_BSIZE).

misc fixes and improvements:
-call setlocale(LC_CTYPE, "") before nl_langinfo(CODESET) if the
locale settings is (still) at "C" - otherwise the CODESET doesn't work
-fix the type of the WACS_* symbols -- this needs to be cchar_t*
-add safeguards where the return value of wcwidth() is used for
loop counters or indexing -- it can be -1
-use more common code in the widechar support case -- in particular
let the wchar functions do the work even if chtype ones were called
-implement wcursyncup/wsyncup/wsyncdown
-somewhat experimental: allow ACS_* variables to refer to WACS_*
table entries -- this way, programs using the old chtype using API
can use UTF8 line drawing on terminals which support UTF8 but not
ACS switching
-fix some logics bugs in UTF8 recognition and ALTCHARSET handling

genfs_do_getpages_xip: Drop vmobjlock before calling VOP_BMAP, otherwise
deadlock.  No idea how this worked for me before.

Directly call uvm_phys_to_vm_page_device() to make a device page cookie.

(uebayasi)

Introduce uvm_page_physload_device().  This registers a physical address
range of a device, similar to uvm_page_physload() for memories.  For now,
this is supposed to be called by MD code.  We have to consider the design
when we'll manage mmap'able character devices.

Expose paddr_t -> struct vm_page * conversion function for device pages,
uvm_phys_to_vm_page_device().  This will be called by XIP vnode pager.
Because it knows if a given vnode is a device page (and its physical
address base) or not.  Don't look up device segments, but directly make a
cookie.

(uebayasi)

Don't forget opt_device_page.h.

(uebayasi)

uvm_fault_lower_promote: One more missing part for device pages to by-pass
page cache handling.  When a page in a uobj is promoted, its content is copied
to another owned by the newly allocated anon.  The old page cache is then
disposed.  Of course we don't need to dispose device pages in such a case,
so skip it.

Don't forget opt_device_page.h.
