164 submitted ioctl to clear the video buffer
165 prior to starting video capture
166 Amancio : clean up yuv12 so that it does not
167 affect rgb capture. Basically, fxtv after
168 capturing in yuv12 mode , switching to rgb
169 would cause the video capture to be too bright.
1701.32 disable inverse gamma function for rgb and yuv
171 capture. fixed meteor brightness ioctl it now
172 converts the brightness value from unsigned to
173 signed.
1741.33 added sysctl: hw.bt848.tuner, hw.bt848.reverse_mute,
175 hw.bt848.card
176 card takes a value from 0 to bt848_max_card

178 reverse_mute : 0 no effect, 1 reverse tuner
179 mute function some tuners are wired reversed :(
1801.34 reverse mute function for ims turbo card
181
1821.35 Roger Hardiman <roger@cs.strath.ac.uk>
183 options BROOKTREE_SYSTEM_DEFAULT=BROOKTREE_PAL
184 in the kernel config file makes the driver's
185 video_open() function select PAL rather than NTSC.
186 This fixed all the hangs on my Dual Crystal card
187 when using a PAL video signal. As a result, you
188 can loose the tsleep (of 2 seconds - now 0.25!!)
189 which I previously added. (Unless someone else
190 wanted the 0.25 second tsleep).
191
1921.36 added bt848.format sysctl variable.
193 1 denotes NTSC , 0 denotes PAL
194
1951.37 added support for Bt878 and improved Hauppauge's
196 bt848 tuner recognition
1971.38 Further improvements on Hauppauge's rely on

211 Added Capture Area ioctl - BT848[SG]CAPAREA.
212 Normally the full 640x480 (768x576 PAL) image
213 is grabbed. This ioctl allows a smaller area
214 from anywhere within the video image to be
215 grabbed, eg a 400x300 image from (50,10).
216 See restrictions in BT848SCAPAREA.
217
2181.50 31 August 1998 Roger Hardiman <roger@cs.strath.ac.uk>

333
3341.68 25 May 1999 Roger Hardiman <roger@freebsd.org>
335 Due to differences in PCI bus implementations from various
336 motherboard chipset manufactuers, the Bt878/Bt879 has 3
337 PCI bus compatibility modes. These are
338 NORMAL PCI 2.1 for proper PCI 2.1 compatible chipsets.
339 INTEL 430 FX for the Intel 430 FX chipset.
340 SIS VIA CHIPSET for certain SiS and VIA chipsets.
341 Older Intel and non-Intel chipsets may also benefit from
342 either 430_FX or SIS/VIA mode.
343
344 NORMAL PCI mode is enabled by default.
345 For INTEL 430 FX mode, add this to your kenel config:
346 options "BKTR_430_FX_MODE"
347 For SiS / VIA mode, add this to your kernel config:
348 options "BKTR_SIS_VIA_MODE"
349
350 Using quotes in these options is not needed in FreeBSD 4.x.
351
352 Note. Newer VIA chipsets should be fully PCI 2.1 compatible
353 and should work fine in the Default mode.
354
355 Also rename 849 to 849A, the correct name for the chip.

458 enabled by setting the sysctl, hw.bt848.slow_msp_audio to 1
459 before starting FXTV (or before opening /dev/bktrN)
460
4612.09 20 Mar 2000 Thomas Klausner <wiz@danbala.ifoer.tuwien.ac.at> submitted
462 patches to include the NetBSD and OpenBSD support from driver
463 1.74 into the new 2.xx driver. NetBSD is tested. OpenBSD is
464 untested.
465 Also fixed coding error in bktr_audio.c spotted by Thomas.
466 Change xxx_ioctl functions to use ioctl_cmd_t for the cmd
467 parameter. Found by looking at OpenBSDs change logs.
468 Delete PROT_EXEC from OpenBSD (as per OpenBSD cvs logs).
469
4702.10 4 Apr 2000 Convert to using bus_space() to access the Bt848/878 registers
471 rather than using a memory mapped structure. This makes the
472 driver portable to other architectures, like Alpha and PPC.
473 This was done by Thomas Klausner <wiz@netbsd.org> and
474 myself Roger Hardiman <roger@freebsd.org>
475
4762.11 15 Apr 2000 Made changes so the driver compiles on FreeBSD/Alpha.
477 Stop printing MSP autodetect. Requested by
478 Chris D. Faulhaber <jedgar@fxp.org>
479
4802.12 16 Apr 2000 Set adelay as an 8 bit value, noticed by
481 Thomas Klausner <wiz@netbsd.org>
482 Fix typo in the new interrupt code.
483
4842.12 20 May 2000 Merge in NetBSD changes from Thomas Klausner <wiz@netbsd.org>
485 following the import of driver 2.12 into NetBSD
486
4872.13 26 Jun 2000 Merge in more changes from Thomas Klausner <wiz@netbsd.org>
488 syncing this driver with the NetBSD source at 25th June.
489
4902.14 28 Jun 2000 Add new Hauppauge Tuner Types, supplied by Hauppauge and
491 required for Josef Karthauser <joe@pavilion.net>
492 Change the structure of some of the #include files and
493 merge in more NetBSD changes.
494
4952.15 10 Sep 2000 Add support for bktr_mem, a module to hold onto the bktr
496 drives's contiguous memory buffers even when it is unloaded
497 and reloaded.
498 Simplify the use of the optional SMBUS i2c code by using a new
499 #define called BKTR_USE_FREEBSD_SMBUS.
500 Poul-Henning Kamp <phk@freebsd.org> changed the DEVFS code.
501 Peter Wemm <peter@freebsd.org> fixed an SMBUS warning.
502 Alexander Langer <alex@cichlids.com> fixed some FreeBSD newbus
503 resource allocation problems (FreeBSD PR kern/18744).
504
5052.16 19 Sep 2000 Merge in NetBSD changes from Thomas Klausner <wiz@netbsd.org>
506
5072.17 19 Oct 2000 Alexander Langer <alex@big.endian.de> and
508 Daniel O'Connor <doconnor@gsoft.com.au>

164 submitted ioctl to clear the video buffer
165 prior to starting video capture
166 Amancio : clean up yuv12 so that it does not
167 affect rgb capture. Basically, fxtv after
168 capturing in yuv12 mode , switching to rgb
169 would cause the video capture to be too bright.
1701.32 disable inverse gamma function for rgb and yuv
171 capture. fixed meteor brightness ioctl it now
172 converts the brightness value from unsigned to
173 signed.
1741.33 added sysctl: hw.bt848.tuner, hw.bt848.reverse_mute,
175 hw.bt848.card
176 card takes a value from 0 to bt848_max_card
177 tuner takes a value from 0 to bt848_max_tuner
178 reverse_mute : 0 no effect, 1 reverse tuner
179 mute function some tuners are wired reversed :(
1801.34 reverse mute function for ims turbo card
181
1821.35 Roger Hardiman <roger@cs.strath.ac.uk>
183 options BROOKTREE_SYSTEM_DEFAULT=BROOKTREE_PAL
184 in the kernel config file makes the driver's
185 video_open() function select PAL rather than NTSC.
186 This fixed all the hangs on my Dual Crystal card
187 when using a PAL video signal. As a result, you
188 can loose the tsleep (of 2 seconds - now 0.25!!)
189 which I previously added. (Unless someone else
190 wanted the 0.25 second tsleep).
191
1921.36 added bt848.format sysctl variable.
193 1 denotes NTSC , 0 denotes PAL
194
1951.37 added support for Bt878 and improved Hauppauge's
196 bt848 tuner recognition
1971.38 Further improvements on Hauppauge's rely on
198 eeprom[9] to determine the tuner type 8)
199

208 with FreeBSD CVS numbers.
209
2101.49 10 August 1998 Roger Hardiman <roger@cs.strath.ac.uk>
211 Added Capture Area ioctl - BT848[SG]CAPAREA.
212 Normally the full 640x480 (768x576 PAL) image
213 is grabbed. This ioctl allows a smaller area
214 from anywhere within the video image to be
215 grabbed, eg a 400x300 image from (50,10).
216 See restrictions in BT848SCAPAREA.
217
2181.50 31 August 1998 Roger Hardiman <roger@cs.strath.ac.uk>
219 Renamed BT848[SG]CAPAREA to BT848_[SG]CAPAREA.

332 before starting video capture.
333
3341.68 25 May 1999 Roger Hardiman <roger@freebsd.org>
335 Due to differences in PCI bus implementations from various
336 motherboard chipset manufactuers, the Bt878/Bt879 has 3
337 PCI bus compatibility modes. These are
338 NORMAL PCI 2.1 for proper PCI 2.1 compatible chipsets.
339 INTEL 430 FX for the Intel 430 FX chipset.
340 SIS VIA CHIPSET for certain SiS and VIA chipsets.
341 Older Intel and non-Intel chipsets may also benefit from
342 either 430_FX or SIS/VIA mode.
343
344 NORMAL PCI mode is enabled by default.
345 For INTEL 430 FX mode, add this to your kenel config:
346 options "BKTR_430_FX_MODE"
347 For SiS / VIA mode, add this to your kernel config:
348 options "BKTR_SIS_VIA_MODE"
349
350 Using quotes in these options is not needed in FreeBSD 4.x.
351
352 Note. Newer VIA chipsets should be fully PCI 2.1 compatible
353 and should work fine in the Default mode.
354
355 Also rename 849 to 849A, the correct name for the chip.
356

421 Updated AVerMedia audio sources to support FM and Line In
422 sources properly. (Based on info supplied by AVerMedia)
423 Make PLL mode the default for Bt878 chips. This means PAL
424 Bt878 users no longer need the BKTR_USE_PLL kernel option.
425 Detect and auto-configure Dolby Surround Sound DPL3518A chip
426 on Hauppauge WinTV Theater. From Frank Nobis <fn@radio-do.de>
427

429 Cyrille Lefevre <clefevre@citeweb.net>
430 Updated clipping code, ready for Xv support in XFree86 4.0,
431 submitted by Thomas Mueller <tmueller@thmu.de>
432 Thomas also has information on a LynxOS port of this driver.
433 Phase out the rgb_prog RISC program and use rgb_vbi_prog as
434 the default. Now you no longer have to open /dev/vbi
435 before /dev/bktr. - Roger Hardiman <roger@freebsd.org>
436
4372.06 7 Dec 1999 Fix bug which made the tuner fail on cards detected as
438 IMS Turbo. Found by Patrick Mackeown<pgm@NS4.HELP-DESK.CO.UK>
439 Put back some Hauppauge Tuner Types I deleted my mistake.
440 Backout the switch from rgb_prob to rgb_vbi_prog due to
441 problems with NTSC users.
442
4432.07 24 Jan 2000 Update i2c code to build on FreeBSD 3.x and 4.x machines.
444 Added GPIO audio values for the Askey/Dynalink TV card

449 Daniel Dagneaux <dagneaux@lure.u-psud.fr>
450
4512.08 6 Mar 2000 Reinstate rgb_vbi_prog as the default RISC program for
452 PAL video. This does not want to work for NTSC, which will
453 continue to use the rgb_prog RISC program.
454 Add support for cable channels above channel 100.
455 Submitted by Scott Presnell <srp@zgi.com>
456 New MSP3410/3415 setup code submitted by
457 Frank Nobis<fn@radio-do.de>. This is experimental and is
458 enabled by setting the sysctl, hw.bt848.slow_msp_audio to 1
459 before starting FXTV (or before opening /dev/bktrN)
460
4612.09 20 Mar 2000 Thomas Klausner <wiz@danbala.ifoer.tuwien.ac.at> submitted
462 patches to include the NetBSD and OpenBSD support from driver
463 1.74 into the new 2.xx driver. NetBSD is tested. OpenBSD is
464 untested.
465 Also fixed coding error in bktr_audio.c spotted by Thomas.
466 Change xxx_ioctl functions to use ioctl_cmd_t for the cmd
467 parameter. Found by looking at OpenBSDs change logs.
468 Delete PROT_EXEC from OpenBSD (as per OpenBSD cvs logs).
469
4702.10 4 Apr 2000 Convert to using bus_space() to access the Bt848/878 registers
471 rather than using a memory mapped structure. This makes the
472 driver portable to other architectures, like Alpha and PPC.
473 This was done by Thomas Klausner <wiz@netbsd.org> and
474 myself Roger Hardiman <roger@freebsd.org>
475

481 Thomas Klausner <wiz@netbsd.org>
482 Fix typo in the new interrupt code.
483
4842.12 20 May 2000 Merge in NetBSD changes from Thomas Klausner <wiz@netbsd.org>
485 following the import of driver 2.12 into NetBSD
486
4872.13 26 Jun 2000 Merge in more changes from Thomas Klausner <wiz@netbsd.org>
488 syncing this driver with the NetBSD source at 25th June.
489

491 required for Josef Karthauser <joe@pavilion.net>
492 Change the structure of some of the #include files and
493 merge in more NetBSD changes.
494
4952.15 10 Sep 2000 Add support for bktr_mem, a module to hold onto the bktr
496 drives's contiguous memory buffers even when it is unloaded
497 and reloaded.
498 Simplify the use of the optional SMBUS i2c code by using a new
499 #define called BKTR_USE_FREEBSD_SMBUS.
500 Poul-Henning Kamp <phk@freebsd.org> changed the DEVFS code.
501 Peter Wemm <peter@freebsd.org> fixed an SMBUS warning.
502 Alexander Langer <alex@cichlids.com> fixed some FreeBSD newbus
503 resource allocation problems (FreeBSD PR kern/18744).
