Basically, fxtv after 166 capturing in yuv12 mode , switching to rgb 167 would cause the video capture to be too bright. 1681.32 disable inverse gamma function for rgb and yuv 169 capture. fixed meteor brightness ioctl it now 170 converts the brightness value from unsigned to 171 signed. 1721.33 added sysctl: hw.bt848.tuner, hw.bt848.reverse_mute, 173 hw.bt848.card 174 card takes a value from 0 to bt848_max_card 175 tuner takes a value from 0 to bt848_max_tuner 176 reverse_mute : 0 no effect, 1 reverse tuner 177 mute function some tuners are wired reversed :( 1781.34 reverse mute function for ims turbo card 179 1801.35 Roger Hardiman <roger@cs.strath.ac.uk> 181 options BROOKTREE_SYSTEM_DEFAULT=BROOKTREE_PAL 182 in the kernel config file makes the driver's 183 video_open() function select PAL rather than NTSC. 184 This fixed all the hangs on my Dual Crystal card 185 when using a PAL video signal. As a result, you 186 can lose the tsleep (of 2 seconds - now 0.25!!) 187 which I previously added. (Unless someone else 188 wanted the 0.25 second tsleep). 189 1901.36 added bt848.format sysctl variable. 191 1 denotes NTSC , 0 denotes PAL 192 1931.37 added support for Bt878 and improved Hauppauge's 194 bt848 tuner recognition 1951.38 Further improvements on Hauppauge's rely on 196 eeprom[9] to determine the tuner type 8) 197 198 AVerMedia card type added <sos@freebsd.org> 199 2001.39 08/05/98 Roger Hardiman <roger@cs.strath.ac.uk> 201 Updated Hauppauge detection code for Tuner ID 0x0a 202 for newer NTSC WinCastTV 404 with Bt878 chipset. 203 Tidied up PAL default in video_open() 204 205 Soren bumped version from 1.39 to 1.49 to sync 206 with FreeBSD CVS numbers. 207 2081.49 10 August 1998 Roger Hardiman <roger@cs.strath.ac.uk> 209 Added Capture Area ioctl - BT848[SG]CAPAREA. 210 Normally the full 640x480 (768x576 PAL) image 211 is grabbed. This ioctl allows a smaller area 212 from anywhere within the video image to be 213 grabbed, eg a 400x300 image from (50,10). 214 See restrictions in BT848SCAPAREA. 215 2161.50 31 August 1998 Roger Hardiman <roger@cs.strath.ac.uk> 217 Renamed BT848[SG]CAPAREA to BT848_[SG]CAPAREA. 218 Added PR kern/7177 for SECAM Video Highway Xtreme 219 with single crystal PLL configuration 220 submitted by Vsevolod Lobko <seva@alex-ua.com>. 221 In kernel configuration file add 222 options OVERRIDE_CARD=2 223 options OVERRIDE_TUNER=11 224 options BKTR_USE_PLL 225 2261.51 31 August 1998 Roger Hardiman <roger@cs.strath.ac.uk> 227 Fixed bug in Miro Tuner detection. Missing Goto. 228 Removed Hauppauge EEPROM 0x10 detection as I think 229 0x10 should be a PAL tuner, not NTSC. 230 Reinstated some Tuner Guesswork code from 1.27 231 2321.52 3 Sep 1998 Roger Hardiman <roger@cs.strath.ac.uk> 233 Submitted patch by Vsevolod Lobko <seva@alex-ua.com> 234 to correct SECAM B-Delay and add XUSSR channel set. 235 2361.53 9 Sep 1998 Roger Hardiman <roger@cs.strath.ac.uk> 237 Changed METEORSINPUT for Hauppauge cards with bt878. 238 Submitted by Fred Templin <templin@erg.sri.com> 239 Also fixed video_open defines and 878 support. 240 2411.54 18 Sep 1998 Roger Hardiman <roger@cs.strath.ac.uk> 242 Changed tuner code to autodetect tuner i2c address. 243 Addresses were incorrectly hardcoded. 244 2451.55 21 Sep 1998 Roger Hardiman <roger@cs.strath.ac.uk> 246 Hauppauge Tech Support confirmed all Hauppauge 878 247 PAL/SECAM boards will use PLL mode. 248 Added to card probe.

From Randal Hopper<aa8vb@ipass.net> 287 Add option to block the reset of the MSP34xx audio chip by 288 adding options BKTR_NO_MSP_RESET to the kernel config file. 289 This is useful if you run another operating system 290 first to initialise the audio chip, then do a soft reboot. 291 Added for Yuri Gindin <yuri@xpert.com> 292 2931.62 29 Apr 1999 Added new cards: NEC PK-UG-X017 and I/O DATA GV-BCTV2/PCI 294 Added new tuner: ALPS_TSBH1 (plus FM Radio for ALPS_TSCH5) 295 Added support for BCTV audio mux. 296 All submitted by Hiroki Mori <mori@infocity.co.jp> 297 2981.63 29 Apr 1999 Roger Hardiman <roger@freebsd.org> 299 Added initial code for VBI capture based on work by 300 Hiroki Mori <mori@infocity.co.jp> and reworked by myself. 301 This allows software decoding of teletext, intercast and 302 subtitles via /dev/vbi. 303 3041.64 7 May 1999 Roger Hardiman <roger@freebsd.org> 305 Support LifeView FlyVideo 98 cards. Use EEPROM for card 306 autodetection. Use bttv's audio mux values. 307 Thanks to Paul Reece <paul@fastlane.net.au>, 308 Ivan Brawley <brawley@internode.com.au> and 309 Gilad Rom <rom_glsa@ein-hashofet.co.il> 310 Automatically locate the EEPROM i2c address and read the 311 subsystem_vendor_id from EEPROM and not the PCI registers. 312 Add NSMBUS checks around smbus/iicbus i2c bus code 313 making it easier to compile the driver under 2.2.x. 314 Add GPIO mask for the audio mux to each card type. 315 Add CARD_ZOLTRIX and CARD_KISS from mailing list searches. 316 3171.65 18 May 1999 Roger Hardiman <roger@freebsd.org> 318 Change Intel GPIO mask to stop turning the Intel Camera off 319 Fixed tuner selection on Hauppauge card with tuner 0x0a 320 Replaced none tuner with no tuner for Theo de Raadt. 321 Ivan Brawley <brawley@internode.com.au> added 322 the Australian channel frequencies. 323 3241.66 19 May 1999 Ivan Brawley <brawley@internode.com.au> added better 325 Australian channel frequencies. 326 3271.67 23 May 1999 Roger Hardiman <roger@freebsd.org> 328 Added rgb_vbi_prog() to capture VBI data and video at the 329 same time. To capture VBI data, /dev/vbi must be opened 330 before starting video capture. 331 3321.68 25 May 1999 Roger Hardiman <roger@freebsd.org> 333 Due to differences in PCI bus implementations from various 334 motherboard chipset manufactuers, the Bt878/Bt879 has 3 335 PCI bus compatibility modes. These are 336 NORMAL PCI 2.1 for proper PCI 2.1 compatible chipsets. 337 INTEL 430 FX for the Intel 430 FX chipset. 338 SIS VIA CHIPSET for certain SiS and VIA chipsets. 339 Older Intel and non-Intel chipsets may also benefit from 340 either 430_FX or SIS/VIA mode. 341 342 NORMAL PCI mode is enabled by default. 343 For INTEL 430 FX mode, add this to your kenel config: 344 options "BKTR_430_FX_MODE" 345 For SiS / VIA mode, add this to your kernel config: 346 options "BKTR_SIS_VIA_MODE" 347 348 Using quotes in these options is not needed in FreeBSD 4.x. 349 350 Note. Newer VIA chipsets should be fully PCI 2.1 compatible 351 and should work fine in the Default mode. 352 353 Also rename 849 to 849A, the correct name for the chip. 354 3551.69 12 June 1999 Roger Hardiman <roger@freebsd.org> 356 Updates for FreeBSD 4.x device driver interface. 357 BSDI code removed. Will be restored later. 358 3591.70 12 July 1999 Roger Hardiman <roger@freebsd.org> 360 Reorganise OS device dependant parts (based on a port to 361 linux by Brad Parker). 362 Make the driver compile on FreeBSD 2.2.x systems again. 363 Change number of VBI lines from 16 to 12 for NTSC formats. 364 Changes to probeCard() for better eeprom identification. 365 Added STB Bt878 card identification. 366 Add Hauppauge model identification to probeCard(). 367 Added TDA9850 initialisation code taken from Linux bttv. 368 Juha.Nurmela@quicknet.inet.fi found/fixed bug in VBI_SLEEP. 369 Matt Brown <matt@dqc.org> added MSP3430G DBX initialisation. 370 3711.71 30 Aug 1999 Roger Hardiman <roger@freebsd.org> 372 Small cleanup of OS dependant code.

Now you no longer have to open /dev/vbi 433 before /dev/bktr. - Roger Hardiman <roger@freebsd.org> 434 4352.06 7 Dec 1999 Fix bug which made the tuner fail on cards detected as 436 IMS Turbo. Found by Patrick Mackeown<pgm@NS4.HELP-DESK.CO.UK> 437 Put back some Hauppauge Tuner Types I deleted my mistake. 438 Backout the switch from rgb_prob to rgb_vbi_prog due to 439 problems with NTSC users. 440 4412.07 24 Jan 2000 Update i2c code to build on FreeBSD 3.x and 4.x machines. 442 Added GPIO audio values for the Askey/Dynalink TV card 443 taken from postings on the V4L mailing list. 444 Update Australian Channel Set. Submitted by 445 John Birrell <jb@cimlogic.com.au> 446 Add new Channel Set for France. Submitted by 447 Daniel Dagneaux <dagneaux@lure.u-psud.fr> 448 4492.08 6 Mar 2000 Reinstate rgb_vbi_prog as the default RISC program for 450 PAL video. This does not want to work for NTSC, which will 451 continue to use the rgb_prog RISC program. 452 Add support for cable channels above channel 100. 453 Submitted by Scott Presnell <srp@zgi.com> 454 New MSP3410/3415 setup code submitted by 455 Frank Nobis<fn@radio-do.de>. This is experimental and is 456 enabled by setting the sysctl, hw.bt848.slow_msp_audio to 1 457 before starting FXTV (or before opening /dev/bktrN) 458 4592.09 20 Mar 2000 Thomas Klausner <wiz@danbala.ifoer.tuwien.ac.at> submitted 460 patches to include the NetBSD and OpenBSD support from driver 461 1.74 into the new 2.xx driver. NetBSD is tested. OpenBSD is 462 untested. 463 Also fixed coding error in bktr_audio.c spotted by Thomas. 464 Change xxx_ioctl functions to use ioctl_cmd_t for the cmd 465 parameter. Found by looking at OpenBSDs change logs. 466 Delete PROT_EXEC from OpenBSD (as per OpenBSD cvs logs). 467 4682.10 4 Apr 2000 Convert to using bus_space() to access the Bt848/878 registers 469 rather than using a memory mapped structure.
