Code Issues Releases Activity

Upgrade the bktr driver from 2.07 to 2.10.

Browse Source 
- The driver now uses bus_space() and runs on NetBSD 1.4.2
   Submitted by Thomas Klausner <wiz@danbala.ifoer.tuwien.ac.at>

 - Remove startup quirks for video and vbi capture for PAL users.
   PAL TV users can now run FXTV and Alevt in any order.

 - Add support for cable channels >100
   Submitted by Scott Presnell <srp@zgi.com>

 - New MSP3410/3415 setup code added. This is experimental.
   Please set the sysctl hw.bt848.slow_msp_audio to 1 for this.

@ -442,10 +442,34 @@
2.07 24 Jan 2000 Update i2c code to build on FreeBSD 3.x and 4.x machines.
Added GPIO audio values for the Askey/Dynalink TV card
taken from postings on the V4L mailing list.

Update Australian Channel Set. Submitted by

Add new Channel Set for France. Submitted by

Daniel Dagneaux <dagneaux@lure.u-psud.fr>
2.08 6 Mar 2000 Reinstate rgb_vbi_prog as the default RISC program for
PAL video. This does not want to work for NTSC, which will
continue to use the rgb_prog RISC program.
Add support for cable channels above channel 100.
Submitted by Scott Presnell <srp@zgi.com>
New MSP3410/3415 setup code submitted by
Frank Nobis<fn@radio-do.de>. This is experimental and is
enabled by setting the sysctl, hw.bt848.slow_msp_audio to 1
before starting FXTV (or before opening /dev/bktrN)
2.09 20 Mar 2000 Thomas Klausner <wiz@danbala.ifoer.tuwien.ac.at> submitted
patches to include the NetBSD and OpenBSD support from driver
1.74 into the new 2.xx driver. NetBSD is tested. OpenBSD is
untested.
Also fixed coding error in bktr_audio.c spotted by Thomas.
Change xxx_ioctl functions to use ioctl_cmd_t for the cmd
parameter. Found by looking at OpenBSDs change logs.
Delete PROT_EXEC from OpenBSD (as per OpenBSD cvs logs).
2.10 4 Apr 2000 Convert to using bus_space() to access the Bt848/878 registers
rather than using a memory mapped structure. This makes the
driver portable to other architectures, like Alpha and PPC.
This was done by Thomas Klausner <wiz@netbsd.org> and
myself Roger Hardiman <roger@freebsd.org>
