Leave a note about what this code probably should look like for
anyone who comes rummaging around with the intent to really fix it.
I would do that myself if I had time and resources to test this at
the moment, and more comfort with our firewire stack, but I don't.
This is a work-in-progress driver for USB trackpads found in Apple
laptops since 2005, theoretically covering more models than pbms(4)
and supporting more features. However, the motion smoothing and
acceleration formulae are still pretty sketchy, and I have tested
this only on one model of MacBook from 2006. Feedback welcome.
Should the smooting, acceleration, tapping, &c., be done in userland?
Probably, but we don't have the necessary interface for that to work
well yet -- wsmouse isn't enough as is.
This way, if anything fails, it just fails; you don't panic. This can
happen if suspending and resuming of firewire is broken (e.g., as I
encountered in PR kern/44581).
This triggers when processing an RX interrupt that was queued while
stopping the interface, which caused my machine to panic last night.
In this case, just drop the packet.
From OpenBSD's if_msk.c rev. 1.71.
ATA drives to not be detected when the PATA (or emulated PATA) bus is shared
with an ATAPI device.
Should fix the problem reported by various peoples.
Thanks to Onno van der Linden and vanoven@free.fr for pointing out the
code in error.
Ported from OpenBSD
Known issues :
- contrary to OpenBSD one, only support pci at the moment, because I don't
have the necessary hardware to test PCMCIA / CARDUS Marvell Card
- not connected to pmf(9) (unable to test it)

First step in reverting regressions to ata(4) subsystem during the addition of
port multiplier support.
port multiplier register access. Thus, in the LBA48 case, pass the complete
r(hd|dh)_dh byte back and forth to the upper layers. (This is irrelevant in
the LBA28/CHS code path for what should be obvious reasons.)
usb_create_event_thread() back into usb_doattach(), so that eg,
usb_discover() never operates when the root_hub is not setup.
fixes a crash joerg@ reported.
- create the task/event threads in usb_attach() so they're more likely
to be ready when usb_doattach() runs
- move the task thread creation into usb_once_init(), instead of having
some other method of only creating them once
drain of watermask words, pause a bit to give time for the fifo to recover.
Always the command response in BE byteorder. Rewrite __bitfield to deal
with this.
fix is not ready yet:
move the clear endpoint stall async call into the task thread,
to avoid trying to call kmem_alloc() from a softint thread.
XXX ideally moving callbacks into the task thread (or perhaps
a different high priority task thread) would be better than this
workaround, once that method is working.
Prefix the DRIVE_ and DRIVET_ constants from atavar.h with ATA_.
Don't use an enum for drive_type - you don't know how big it will be.
Move driver_type to avoid implicit structure padding (esp on arm).
This change is purely lexical and mechanical.
Update to 6.99.9 - this wasn't done when the SATA PMP changes
were made - I'm sure they warranted a bump.
Apparently on some CG6 the GX_FULL bit is not a reliable indication wether the
engine is ready to accept another command ( LX onboard for example ) - might
be a hardware bug.
As we always want response data in LE, use bus_space_read_stream.
Additonally, read response data in 1 or 4 4-byte chunks, instead of
one 4-byte chunk or 15 1-byte chunks.
unfortunately failed on at least one 'real' SCSI MSCP adaptor.
In the updated code mscp_attach() still iterates over each unit on a bus,
but mscp_dorsp() now detects if we have reached the last unit and does not
return a bogus additional unit. It also loses a few gotos and handles
noncontiguous unit numbers better.

as described in

PMP support in integrated to the atabus layer.
struct ata_channel's ch_drive[] is not dynamically allocated, and ch_ndrive
(renamed to ch_ndrives) closely reflects the size of the ch_drive[] array.
Add helper functions atabus_alloc_drives() and atabus_free_drives()
to manage ch_drive[]/ch_ndrives.
Add wdc_maxdrives to struct wdc_softc so that bus front-end can specify
how much drive they really support (master/slave or single).
ata_reset_drive() callback gains a uint32_t *sigp argument which,
when not NULL, will contain the signature of the device being reset.
While there, some cosmetic changes:
- added a drive_type enum to ata_drive_datas, and stop encoding the
probed drive type in drive_flags (we were out of drive flags anyway).
- rename DRIVE_ATAPIST to DRIVE_ATAPIDSCW to better reflect what this
really is
- remove ata_channel->ata_drives, it's redundant with the pointer in
ata_drive_datas
- factor out the interpretation of SATA signatures in sata_interpet_sig()
propagate these changes to the ATA HBA drivers, and add support for PMP
to ahcisata(4) and siisata(4).
Thanks to:
- Protocase (http://www.protocase.com/) which provided a system
with lots of controllers, SATA PMP and drive slots
- Conservation Genomics Laboratory, Department of Biology, New Mexico State
University for hosting the above system
- Brook Milligan, who set up remote access and has been very responsive
when SATA cable move was needed
- add an additional watchdog for RX overflow
- re-initialise the chip on device timeout
Also alter the interrupt blanking rate to 8 packets, as per OpenSolaris.
in the case where it's configured in MD md_open_hook().
Without this, msdosfs_mountfs() (which is called from msdosfs_mountroot())
will be called with uninitialized disklabel (d_secsize == 0) and
it gets "panic: buf mem pool index 23" later on atari.
This is because getdisksize() doesn't check returned d_secsize value
and msdosfs_mountfs() blindly calls bread(9) with size==0 in that case.
Should be pulled up to netbsd-6 (at least for atari).
still reports a number of bytes transfered equal to bcount.
This then triggers a KASSERT in physio_biodone:
if (done == todo)
KASSERT(bp->b_error == 0);
Detect this case in wd(4) (so that the workaround works for other controllers
too if they have the same issue, or if the issue is with the drive)
and claim we didn't read/write anything.
to mixing them in with the ra* disks, modelled loosely on how MSCP
rx* floppies are handled
- racd* defaults to the same single iso9660 partition as cd*
- Cleanup config option handling slightly so any combination of ra*,
rx* (and now raccd*) can be defined without build errors.
- Avoid ugly printf when disks have all zero disklabel magic number
command to be transfered via dma" (sc_cmdlen) to zero upfront, otherwise we
might get confused on command completition interrupt (no dma active but still
data left to transfer).
adapt the urtwn(4) driver to use the new files. The firmware files were
extracted from the Linux driver at www.realtek.com, version 0005.1230.2011
and the license permits redistribution without modification.
While I'm here, install the files in /libdata/firmware/if_urtwn, like
most of the other network adapter firmware.
urtwn(4) can now operate without needing external files installed. Tested
on my Edimax adapter.
initial work, and every one else who has tested things for me.
this is largely my fault at this point :-)
the main changes are something like:
- usbd_bus_methods{} gains a get_lock() to enable the
host controller to provide a lock for the USB code.
if the lock isn't provided, old-style protection is
(partially) applied.
- ehci/ohci/uhci have been converted to the new
interfaces, including mutex/cv/etc conversion.
- usbdivar.h contains a discussion about locking and
what locks are held for which method calls. more
to come for usbdi(9) here.
- audio drivers (uaudio, umidi, auvitek) have been
properly SMPified now that USB is ready.
- scsi drivers have been modified to take the kernel
lock explicitly before calling into scsi code.
- usb pipes are associated with a lock, that is the
same as the controller lock. (this could be split
up further in the future.)
- several usbfoo_locked() or usbfoo_unlocked()
functions have been added to the usbdi(9) to
enable functionality with or without the USB
lock (per controller) already being held.
the TODO.usbmp file has specific details on what is left to
do, including what device-specific changes should be done now
that the whole framework is ready.
Fix locking of file handle. More cleanup on error paths.
Keep track of CCBs, so they cannot be used after a session ends.
Handle CCB timeouts even when the connection is terminated.
Compute firstdata, firstimmed correctly.
bytes. Newfs does large writes when initializing the filesystem.
First, don't copy the head of a TAILQ to make a copy - the first entry will
still point back to the original head. This caused the ccb list to link to
itself, resulting in a continous loop processing the same ccb and blocked
interrupts. Use TAILQ_CONCAT() to copy the list.
Next, the ccb disposition was not set in the ccb when the ccb was throttled,
losing the CCBDISP_SCSIPI, so when a throttled ccb was resent, it failed to
call scscipi_done(), and left that I/O hanging.
I am now able to newfs an iSCSI device, was well as issued large writes
using dd.
passed to sysctl_createv() actually matches the declared type for
the item itself.
In the places where the caller specifies a function and a structure
address (typically the 'softc') an explicit (void *) cast is now needed.

(mostly passing the address of a uint64_t when typed as CTLTYPE_INT).
I've test built quite a few kernels, but there may be some unfixed MD
fallout. Most likely passing &char[] to char *.
Also add CTLFLAG_UNSIGNED for unsiged decimals - not set yet.
