- add NULL check to UMQ_ISTYPE; sc_quirk is NULL for genuine umidi, but
forgotten to check. Thus, kernel will panic after connect the device.
- fix how to count the number of endpoints in alloc_all_endpoints_genuine().
- add a quirk for the native mode of UM-880.
- In acpi_print(), try to evaluate the _STR object, and print
it if the device is not configured.
- Make this compile without ACPI_DEBUG, from Masanori Kanaoka.
I have a weird PC-card-style appliance (I'm not sure I may call it a PC card)
whose ``CIS'' reads zeros forever, which caused kernel panic.
For your interest, it is a cooling fan to be inserted to a PC card slot.
(1) Add an IOCTL to tell the Lucent based cards how often to
do an access point scan. These results are returned by
calling another IOCTL to get the most recent scan data.
This function works with prism2 cards as well, but the
data is returned in a different format, or perhaps it is
data only for the closest access point.
(2) For prism2 cards, add the ability to put it into LAN monitor
mode, where (via BPF) all packets can be received. This
mode works best with "wiconfig wi0 -p 3 -f ?" to put the
card into pseudo-IBSS mode (to keep it from channel-hopping
and scanning for access points) and to set the frequency of
the AP you wish to monitor.
The returned data has a partial wi_frame header (down to the
wi_dat_len field) followed by the raw data of the packet.
I have and will put up on http://www.flame.org/NetBSD/wireless/
some simple utilities which do some perhaps interesting things,
like scan for access points, capture packets, etc.
using the ahc driver hang when probing scsi devices. The problem may be in
the ahc driver and not in this change, but back it out until this has been
fixed anyway.
Avoids using bus_dmamem_alloc/bus_dmamem_map at interrupt time.
Should fix PRs kern/13924 and kern/13979 from dive@endersgame.net
- while I'm there convert to use ether_ioctl.
XXX: FH chanset should be calculated by FH hop pattern, but BayStack 650 AP
always specify chanset to fixed value 1. The previous code try to this
hack into awi driver, but it is insufficient because the chanset value
in awi driver may change while scan and it may be different from the
value in receiving beacon/probe-response. So we save encoded FH chanset
into channel in 802.11 common bss information for now.
called via a callout, kick the completion thread to run it for us (uses
a new flag, SCSIPI_CHAN_KICK).
If we've received BUSY status and we haven't started the completion
thread yet, don't freeze do a callout to scsipi_periph_timed_thaw which
then will try and kick the completion thread- instead treat the command
as if it were a polled command and just call delay for 1 second.
If DIAGNOSTIC is defined, and the periph qfreeze count is less than
zero, panic because some HBA has corrupted the periph structure's
accounting.
if_ieee80211subr.c, which can be shared between any IEEE 802.11
drivers.
However, most of current working IEEE 802.11b wireless LAN cards
have rich firmware and we cannot have a control to management frames
for such cards.
IBSS creation is now supported for the awi driver.
IIR_NOPEND if the TXRDY condition is true. Apparently, other chips do
not take TXRDY into account in the IIR_NOPEND case.
Also remove useless assignment (iir = IIR_NOPEND;) in one case.
No response from patch posted on tech-kern 29Aug2001.
time-related system calls through ioctls. For instance, if user daemon is able
to write to /dev/clockctl, then it is able to use the CLOCKCTL_SETTIMEOFDAY
ioctl on it, which will be equivalent to a settimeofday.

- remove special treatment of pager_map mappings in pmaps. this is
required now, since I've removed the globals that expose the address range.
pager_map now uses pmap_kenter_pa() instead of pmap_enter(), so there's
no longer any need to special-case it.
- eliminate struct uvm_vnode by moving its fields into struct vnode.
- rewrite the pageout path. the pager is now responsible for handling the
high-level requests instead of only getting control after a bunch of work
has already been done on its behalf. this will allow us to UBCify LFS,
which needs tighter control over its pages than other filesystems do.
writing a page to disk no longer requires making it read-only, which
allows us to write wired pages without causing all kinds of havoc.
- use a new PG_PAGEOUT flag to indicate that a page should be freed
on behalf of the pagedaemon when it's unlocked. this flag is very similar
to PG_RELEASED, but unlike PG_RELEASED, PG_PAGEOUT can be cleared if the
pageout fails due to eg. an indirect-block buffer being locked.
this allows us to remove the "version" field from struct vm_page,
and together with shrinking "loan_count" from 32 bits to 16,
struct vm_page is now 4 bytes smaller.
- no longer use PG_RELEASED for swap-backed pages. if the page is busy
because it's being paged out, we can't release the swap slot to be
reallocated until that write is complete, but unlike with vnodes we
don't keep a count of in-progress writes so there's no good way to
know when the write is done. instead, when we need to free a busy
swap-backed page, just sleep until we can get it busy ourselves.
- implement a fast-path for extending writes which allows us to avoid
zeroing new pages. this substantially reduces cpu usage.
- encapsulate the data used by the genfs code in a struct genfs_node,
which must be the first element of the filesystem-specific vnode data
for filesystems which use genfs_{get,put}pages().
- eliminate many of the UVM pagerops, since they aren't needed anymore
now that the pager "put" operation is a higher-level operation.
- enhance the genfs code to allow NFS to use the genfs_{get,put}pages
instead of a modified copy.
- clean up struct vnode by removing all the fields that used to be used by
the vfs_cluster.c code (which we don't use anymore with UBC).
- remove kmem_object and mb_object since they were useless.
instead of allocating pages to these objects, we now just allocate
pages with no object. such pages are mapped in the kernel until they
are freed, so we can use the mapping to find the page to free it.
this allows us to remove splvm() protection in several places.
The sum of all these changes improves write throughput on my
decstation 5000/200 to within 1% of the rate of NetBSD 1.5
and reduces the elapsed time for "make release" of a NetBSD 1.5
source tree on my 128MB pc to 10% less than a 1.5 kernel took.
device (rather, the device that carries that attribute) also
carry one or more attributes indicating which type of controller
it might be.
This will allow systems that might have AGP, but would never have
e.g. an Intel PCI-Host bridge, to trim out code that won't be used.
attach time. Allow access to these regions in vga_pci_mmap().
Note: we also have to allow access to the legacy ISA "hole" in
vga_pci_mmap(), since the X server needs to be able to read
the legacy BIOS on many cards.
XXX Need to address the PCI Expansion ROM.
Based on changes from Simon Burge <simonb@wasabisystems.com>.
-Add a really bad hack: The X server (4.1.0 afaict) appearently overwrites
the PGTBL_CTL which contains the base address of the pseudo-GATT.
Restore the original value if we notice this happened.
The X server works now, but only with soft cursor.
-allocate space for DMA segments as much as necessary
-fix format warnings in a debug output
-don't try to access AGP capability stuff in the PCI config header
if it doesn't exist (as on the i810)
function on all (probed) PCI buses:
int pci_find_device(struct pci_attach_args *pa,
int (*match)(struct pci_attach_args *));
The pci_attach_args structure pointed to by pa is filled in if the
device is found, and 1 is returned. Otherwise 0 is returned.
This function is, unfortunately, needed by the i810 agp code. It's
also of use for LKMs.
Also frob pci_probe_bus to take 2 extra args when used by pci_find_device.
Temp work around problems where if we allow for non-polled mailbox commands
we got nailed by hardclock calling is for a timed thaw. Basically, this
means we only enable non-polled mailbox commands in the FC kthread when it
calls isp_fc_runstate.
attributes of some variants of FC f/w (SCCLUN or not). Fake f/w
rev for SBus cards- the f/w versions we're using don't return
version in outgoing mailbox registers like they should.
* teach it to read the MAC addr from the correct place (from OpenBSD)
* change order of intr_dis/establish() and function_en/disable() to
avoid panics on this multifunction card due to the CCR window
not being mapped in intr_dis/establish()
-apply the patch from PR kern/13117 (Onno van der Linden) to make the
hardware cursor disappear more thoroughly
-deal with PR kern/13573: hardware cursor too big, but differently:
we have to obey the font size actually used. At this point, fix the
problem that the cursor got messed up by the initialization of
unrelated screens.
-unref font(s) if a screen is deleted, so they could be unloaded
if dev/wsfont supported it
-add missing pieces to support screen types with font sizes != 8x16
as system console - now
options VGA_CONSOLE_SCREENTYPE="\"80x50\""
options FONT_VT220L8x8
gives you what you'd expect
- Add mpu at cmpci attachment.
- Fix panic during attach on alpha.
- Change register of SPDIF input phase (but undocumented, either).
- Change code for mixer initialization.
- Return 1, not 0, when an interrupt is processed.
More changes to the mixer are pending....
Actually, the silence filler can do any multiple of 8 bits now, but I didn't
allow the parameter check to accept more than 32 bit to avoid confusion
of drivers that fail to check the parameters themselves thoroughly.
This should be changed later.
compiled-in or runtime loaded fonts,
keep font pointers in a LRU queue and load into the adapter on demand,
so we can have more fonts in use than physical font slots
CAUTION: font loading through the wsdisplay device directly into the
adapter doesn't work anymore!
in how interrupts are down- the 23XX has not only a different place to check
for an interrupt, but unlike all other QLogic cards, you have to read the
status as a 32 bit word- not 16 bit words. Rather than have device specific
functions as called from the core module (in isp_intr), it makes more sense
to have the platform/bus modules do the gruntwork of splitting out the
isr, semaphore register and the first outgoing mailbox register (if needed)
*prior* to calling isp_intr (if calling isp_intr is necessary at all).
If all devices can handle 66MHz, then use 66MHz.
Triple the number of configured I/O ranges that we can handle on a bus
(8 was insufficient--originally didn't consider multifunction devices)
Allow one to specify which types of memory to configure, I/O, ROM, or
MEM--for example, one could configure only ROM or only non-ROM.
Ensure that the ROM is disabled if we're not configuring it.
Only set PCI_COMMAND_IO_ENABLE/PCI_COMMAND_MEM_ENABLE if there are valid
memory ranges configured.
little-endian byte-order. This should work out to be a no-op
for LE systems, and allows BE systems to use the board.
Tested on PPC, reviewed by Dante.
NOTE: The board/microcode does have a BIG_ENDIAN mode of operation,
but it's not well-documented. That might be interesting to investigate
at some point in the future, though.
bus (and optionally maps expansion ROMs), and an optional second
pass to disable expansion ROMs that are mapped. This would allow
MD code to possibly execute the expansion ROMs (possibly in an x86
emulator) to configure a device (e.g. a VGA card, which pretty much
needs to be configured by its ROM).
the expansion ROMs on cards, since address decoders may be shared between
the ROM and PCI memory space on some cards (i.e. "only map the ROM if you're
going to use it, and then unmap it when you're done" is the intended
usage).
driver uses direct DMA to mbufs (like other PCI network drivers,
and unlike the old "le at pci" driver), and also supports communication
with the MII-connected PHYs on the 10/100 boards.
