This includes:
- fixing various structure definitions so that the ioctl parameter match
- adding a hw.twa*.driver_version sysctl
- do not refuse multiple device openings, as the management tool will do it.
I'm not sure we are safe. FreeBSD allows multiple openings, and use the
open flag only when an attempt to detach the device is done.
So far it only uses the blitter for scrolling and rectangle filling,
characters are still drawn in software and there's no support for video
mode switching. Virtual consoles are supported via vcons.
Works fine on a PowerBook 3400c.
schemas. Disk information and disk geometry are designed to replace
information currently conveyed to user space using struct disklabel.
- Add a dk_info member to struct disk; a reference to a disk information
dictionary. This dictionary is to be allocated and the reference stored
in struct disk by individual drivers.
- disk_detach0() will release dk_info if non-NULL.
- Convert the wd(4) driver to stash geometry and other disk properties
as the "disk-info" property in its properties dictionary. This needs
some cleanup, but will serve as an example of what to do with other
disk drivers.
plist-based messages and to eliminate looping previously required to
receive a plist from the kernel:
- prop_dictionary_copyin_ioctl() and prop_dictionary_copyout_ioctl()
now take the cmd argument rather than the file open flag. The
read-ness or write-ness of an ioctl command is checked by these
routines to ensure that information is being passed to/from the
userland component properly.
- prop_dictionary_copyout_ioctl() now allocates the memory for the
XML plist on behalf of the userland component by way of uvm_mmap().
The XML plist is copied out to the newly-mapped anonymous region,
and the pointer returned via the plistref.
- prop_dictionary_recv_ioctl() is responsible for munmap()'ing the
region after parsing the XML plist into internal represenatation.
- A new prop_dictionary_sendrecv_ioctl() is added, allowing user space
code to send a dictionary to the kernel and receive one back as a
reply.
Update users of prop_kern for the API changes (Bluetooth).
This constitutes an ABI / protocol change -- but this will also be put
into NetBSD 4.0 so that the first proplib release will implement the new
scheme.
This gets rid of the now-unneded "todclock" and "todservice" attributes
from the footbridge device files, which should allow netwinder to build
again after its conversion to generic TODR.
Resulting kernel verified to boot up OK on gxemul (after my recent
fixes of the gxemul package to emulate free-running timers).
now since some chipset revisions will freak out on the aparent
half-initialisation. Even on my machine i can't seem to get the SPDIF led
to light up so something is wrong.
Also delay the setting of the DMA bits until after the codec detection but
before the enabling of interrupts. Note that the dma has to be explicitly
started when the device is opened.
read/write action. It would panic on a diagnosic assertion. When a scsi
read/write command fails, the whole extent is gone bad so mark all as not
done.
when the bluetooth code is not expecting it to be. During a disconnect, we can
detach the channel that is being disconnected, but its not really safe to detach
any others.
- sco_getopt(..., SO_SCO_MTU, ...) expects the address of a uint16_t,
not an int. So change sc_mtu's type to uint16_t.
- Try a little harder to ensure btsco_round_blocksize() does not
return zero. Prevents a subsequent panic in audio_init_ringbuffer().
