-current. It doesn't work yet as stable as the 3.x/PAO version of the
driver does, however, i get occasional `FDC direction bit not set' and
other weird messages, but it basically works at least.
The old (defunct) #ifdef FDC_YE stuff has been eliminated completely
now, PCMCIA-FDC specific functions have been implemented differently
where needed.
Unfortunately, due to the fact that the traditional PeeCee FDC with
its funny non-contiguous register space (one register for WD1003
harddisk controllers is interleaved into the FDC register set), and
Peter's subsequent changes involving two different bus space handles
for normal FDCs, the changes required for the Y-E stuff are more
complex than i'd love them to be. I've done my best to keep the logic
for normal FDCs intact.
Since the Y-E FDC seems to lose interrupts after a FDC reset
sometimes, i've also replaced the timeout logic in fd_turnoff() to
generate an artificial pseudo interrupt in case of a timeout while the
drive has still outstanding transfers waiting. This avoids the total
starvation of the driver that could be observed with highly damaged
media under 3.x/PAO. This part of the patch has been revied by bde
previously.
I've fixed a number of occasions where previous commits have been
missing the encapuslation of ISA DMA related functions inside
FDC_NODMA checks.
I've added one call to SET_BCDR() during preparation of the format
floppy operation. Floppy formatting has been totally broken before in
3.x/PAO (garbage ID fields have been written to the medium, causing
`wrong cylinder' errors upon media reading). This is just black
magic, i don't have the slightes idea _why_ this needs to be but just
copied over the hack that has been used by the PAO folks in the normal
read/write case anyway.
The entired device_busy() stuff seems to be pointless to me. In any
case, i had to add device_unbusy() calls symmetrical to the
device_busy() calls, otherwise the PCMCIA floppy driver could never be
deactivated. (As it used to be, it caused a `mark the device busier
and busier' situation.) IMHO, all block device drivers should be
marked busy based on active buffers still waiting for the driver, so
the device_unbusy() calls should probably go to biodone(). Only one
other driver (whose name escapes me at the moment) uses device_busy()
calls at all, so i question the value of all this...
I think this entire `device busy' logic simply doesn't fit for PCMCIA
&al. It cannot be the decision of some piece of kernel software to
declare a device `busy by now, you can't remove it', when the actual
physical power of removing it is the user pulling the card. The
kernel simply has to cope with the removal, however busy the device
might have been by the time of the removal, period. Perhaps a force
flag needs to be added?
Upon inserting the card a second time, i get:
WARNING: "fd" is usurping "fd"'s cdevsw[]
WARNING: "fd" is usurping "fd"'s bmaj
I suspect this is related to the XXX comment at the call to
cdevsw_add(). Does anybody know what the correct way is to cleanup
this?
Scroll Point, and 4D/4D+ mice.
- Add a couple of serial mouse PnP IDs.
- Extend the `-z' option so that the second wheel (or the horizontal
movement of the `scroll' device) can be mapped to buttons.
- Microsoft IntelliMouse Explorer: 2 buttons on top, 2 side buttons
and a wheel which also acts as the middle button. The mouse is
recognized as "IntelliMouse Explorer".
- Genius NetScroll Optical: 2 buttons on top, 2 side buttons and a
wheel which also acts as the middle button. The mouse is recognized
as "NetMouse/NetScroll Optical".
- MouseSystems SmartScroll Mouse (OEM from Genius?): 3 buttons on top,
1 side button and a wheel. The mouse is recognized as Genius
"NetScroll".
- IBM ScrollPoint: 2 buttons on top and a stick between the buttons.
The stick can perform "horizontal scroll" in W*ndows environment.
The horizontal movement of the stick is detected. It is currently
mapped to the Z axis movement in the same way as the first wheel.
The mouse is recognized as "MouseMan+", as it is considered to be
a variation of MouseMan.
- A4 Tech 4D and 4D+ mice. These mice have two wheels! The movement
of the second wheel is reported as the Z axis movement in the
same way as the first wheel. These mice are recognized as "4D
Mouse" and "4D+ Mouse".
- Tweak IntelliMouse support code a bit so that less-than-compatible
wheel mice can work properly with the psm driver.
- Add driver configuration flags which correspond to the kernel
options PSM_HOOKRESUME and PSM_RESETAFTERSUSPEND, so that we don't
need to recompile the kernel when we need these functions.
- Properly keep track of the irq resource.
- Add a watchdog timer in case interrupts are lost (experimental).
- Add `detach' function (experimental).
- Properly keep track of resources (I/O ports and irq).
- Use bus_space_read/write() to access the ports.
- Add PnP IDs.
- Add a watchdog timer in case interrupts are lost (experimental).
- Add `detach' function (experimental).
from DWLPX to PCI space. Just a methods holder such that we have a parent
which is a "pcib" and we create a child which is a "pci". Add the appropriate
ivar code (which is for a hose #).
based upon presence/absence of ISA (there is no ISA bus on an 8200- okay,
well, there *could* be one in a DWLPX tray, but we don't support it)).
Most importantly change the interrupt resource map to cover a whole 16
bits. The 8200 uses 16 bit interrupt vectors which we construct that
contain the I/O-board, hose, an pci slot in them, and then we write these
vectors into the appropriate DWLPX registers. At any rate, a flat array
of 64 'IRQs' isn't enough.
to begin with. Redo newbus attachment code so that all the DMA mapping
and further pci attachment is done right. Insert config space functions
(jeez- how do you do type 1 cycles?). Do the interrupt setups, etc.
Basically, this is the core I/O module for 8200s, even though logically
it's the 3rd level down from the nominal principle backplane bus
(turbolaser). Still to be done here: S/G code isn't done yet, so we
better live with 2GB or less primary memory.
code (merge in progress made in NetBSD since the initial import to
FreeBSD). Create dwlpx as the child device. Of course, if we had
more h/w and time, we could find out whether the child device was
a FutureBus module, etc...Anyone ever actually seen one?
clean MI/MD driver, but it *does* actually work at this time. Updated
to use new make_dev stuff. A CONS_DRIVER declaration is also put in
so that this can be the real console for the 8200s.
not the current BPF device should report locally generated packets or not.
This allows sniffing applications to see only packets that are not generated
locally, which can be useful for debugging bridging problems, or other
situations where MAC addresses are not sufficient to identify locally
sourced packets. Default to true for this flag, so as to provide existing
behavior by default.
Introduce two new ioctls, BIOCGSEESENT and BIOCSSEESENT, which may be used
to manipulate this flag from userland, given appropriate privilege.
Modify bpf.4 to document these two new ioctl arguments.

this version include:
- Support for version 2.x firmware (2.42 or later recommended). This
means we are the only open-source driver supporting these adapters.
This code has only been tested on a Digital KZPCA adapter in an Alpha
system, but is believed to be correct. NOTE: EISA adapters are not
yet supported.
- Support the BIOS/Firmware initialisation handshake protocol. This
allows the driver to bring the card up to operational state even if
the BIOS can't be run (eg. if it's an x86 BIOS in an Alpha system).
- A working command pasthrough interface. This allows a user-space
configuration tool (under development) to issue arbitrary commands
to the controller or to devices in the system.
