Linux-2.6.12-rc2v2.6.12-rc2
Initial git repository build. I'm not bothering with the full history, even though we have it. We can create a separate "historical" git archive of that later if we want to, and in the meantime it's about 3.2GB when imported into git - space that would just make the early git days unnecessarily complicated, when we don't have a lot of good infrastructure for it. Let it rip!

16 by Fujitsu-Siemens, Technotrend, Hauppauge and others.

18 This driver only supports the fullfeatured cards with
19 onboard MPEG2 decoder.
20
21 This driver needs an external firmware. Please use the script
22 "<kerneldir>/Documentation/dvb/get_dvb_firmware av7110" to
23 download/extract it, and then copy it to /usr/lib/hotplug/firmware.

32 The AV7110 firmware is normally loaded by the firmware hotplug manager.
33 If you want to compile the firmware into the driver you need to say

50 The AV7110 firmware provides some code to generate an OnScreenDisplay
51 on the video output. This is kind of nonstandard and not guaranteed to
52 be maintained.
53
54 Anyway, some popular DVB software like VDR uses this OSD to render
55 its menus, so say Y if you want to use this software.

2152/* Budgetpatch note:
2153 * Original hardware design by Roberto Deza:
2154 * There is a DVB_Wiki at
2155 * http://212.227.36.83/linuxtv/wiki/index.php/Main_Page
2156 * where is described this 'DVB TT Budget Patch', on Card Modding:
2157 * http://212.227.36.83/linuxtv/wiki/index.php/DVB_TT_Budget_Patch
2158 * On the short description there is also a link to a external file,
2159 * with more details:
2160 * http://perso.wanadoo.es/jesussolano/Ttf_tsc1.zip
2161 *
2162 * New software triggering design by Emard that works on
2163 * original Roberto Deza's hardware:
2164 *
2165 * rps1 code for budgetpatch will copy internal HS event to GPIO3 pin.
2166 * GPIO3 is in budget-patch hardware connectd to port B VSYNC
2167 * HS is an internal event of 7146, accessible with RPS
2168 * and temporarily raised high every n lines
2169 * (n in defined in the RPS_THRESH1 counter threshold)
2170 * I think HS is raised high on the beginning of the n-th line
2171 * and remains high until this n-th line that triggered
2172 * it is completely received. When the receiption of n-th line
2173 * ends, HS is lowered.
2174 *
2175 * To transmit data over DMA, 7146 needs changing state at
2176 * port B VSYNC pin. Any changing of port B VSYNC will
2177 * cause some DMA data transfer, with more or less packets loss.
2178 * It depends on the phase and frequency of VSYNC and
2179 * the way of 7146 is instructed to trigger on port B (defined
2180 * in DD1_INIT register, 3rd nibble from the right valid
2181 * numbers are 0-7, see datasheet)
2182 *
2183 * The correct triggering can minimize packet loss,
2184 * dvbtraffic should give this stable bandwidths:
2185 * 22k transponder = 33814 kbit/s
2186 * 27.5k transponder = 38045 kbit/s
2187 * by experiment it is found that the best results
2188 * (stable bandwidths and almost no packet loss)
2189 * are obtained using DD1_INIT triggering number 2
2190 * (Va at rising edge of VS Fa = HS x VS-failing forced toggle)
2191 * and a VSYNC phase that occurs in the middle of DMA transfer
2192 * (about byte 188*512=96256 in the DMA window).
2193 *
2194 * Phase of HS is still not clear to me how to control,
2195 * It just happens to be so. It can be seen if one enables
2196 * RPS_IRQ and print Event Counter 1 in vpeirq(). Every
2197 * time RPS_INTERRUPT is called, the Event Counter 1 will
2198 * increment. That's how the 7146 is programmed to do event
2199 * counting in this budget-patch.c
2200 * I *think* HPS setting has something to do with the phase
2201 * of HS but I cant be 100% sure in that.
2202 *
2203 * hardware debug note: a working budget card (including budget patch)
2204 * with vpeirq() interrupt setup in mode "0x90" (every 64K) will
2205 * generate 3 interrupts per 25-Hz DMA frame of 2*188*512 bytes
2206 * and that means 3*25=75 Hz of interrupt freqency, as seen by
2207 * watch cat /proc/interrupts
2208 *
2209 * If this frequency is 3x lower (and data received in the DMA
2210 * buffer don't start with 0x47, but in the middle of packets,
2211 * whose lengths appear to be like 188 292 188 104 etc.
2212 * this means VSYNC line is not connected in the hardware.
2213 * (check soldering pcb and pins)
2214 * The same behaviour of missing VSYNC can be duplicated on budget
2215 * cards, by seting DD1_INIT trigger mode 7 in 3rd nibble.

578/* OLD (Original design by Roberto Deza):
579** This code will setup the SAA7146_RPS1 to generate a square
580** wave on GPIO3, changing when a field (TS_HEIGHT/2 "lines" of
581** TS_WIDTH packets) has been acquired on SAA7146_D1B video port;
582** then, this GPIO3 output which is connected to the D1B_VSYNC
583** input, will trigger the acquisition of the alternate field
584** and so on.
585** Currently, the TT_budget / WinTV_Nova cards have two ICs
586** (74HCT4040, LVC74) for the generation of this VSYNC signal,
587** which seems that can be done perfectly without this :-)).
588*/
589
590/* New design (By Emard)
591** this rps1 code will copy internal HS event to GPIO3 pin.
592** GPIO3 is in budget-patch hardware connectd to port B VSYNC
593
594** HS is an internal event of 7146, accessible with RPS
595** and temporarily raised high every n lines
596** (n in defined in the RPS_THRESH1 counter threshold)
597** I think HS is raised high on the beginning of the n-th line
598** and remains high until this n-th line that triggered
599** it is completely received. When the receiption of n-th line
600** ends, HS is lowered.
601
602** To transmit data over DMA, 7146 needs changing state at
603** port B VSYNC pin. Any changing of port B VSYNC will
604** cause some DMA data transfer, with more or less packets loss.
605** It depends on the phase and frequency of VSYNC and
606** the way of 7146 is instructed to trigger on port B (defined
607** in DD1_INIT register, 3rd nibble from the right valid
608** numbers are 0-7, see datasheet)
609**
610** The correct triggering can minimize packet loss,
611** dvbtraffic should give this stable bandwidths:
612** 22k transponder = 33814 kbit/s
613** 27.5k transponder = 38045 kbit/s
614** by experiment it is found that the best results
615** (stable bandwidths and almost no packet loss)
616** are obtained using DD1_INIT triggering number 2
617** (Va at rising edge of VS Fa = HS x VS-failing forced toggle)
618** and a VSYNC phase that occurs in the middle of DMA transfer
619** (about byte 188*512=96256 in the DMA window).
620**
621** Phase of HS is still not clear to me how to control,
622** It just happens to be so. It can be seen if one enables
623** RPS_IRQ and print Event Counter 1 in vpeirq(). Every
624** time RPS_INTERRUPT is called, the Event Counter 1 will
625** increment. That's how the 7146 is programmed to do event
626** counting in this budget-patch.c
627** I *think* HPS setting has something to do with the phase
628** of HS but I cant be 100% sure in that.
629
630** hardware debug note: a working budget card (including budget patch)
631** with vpeirq() interrupt setup in mode "0x90" (every 64K) will
632** generate 3 interrupts per 25-Hz DMA frame of 2*188*512 bytes
633** and that means 3*25=75 Hz of interrupt freqency, as seen by
634** watch cat /proc/interrupts
635**
636** If this frequency is 3x lower (and data received in the DMA
637** buffer don't start with 0x47, but in the middle of packets,
638** whose lengths appear to be like 188 292 188 104 etc.
639** this means VSYNC line is not connected in the hardware.
640** (check soldering pcb and pins)
641** The same behaviour of missing VSYNC can be duplicated on budget
642** cards, by seting DD1_INIT trigger mode 7 in 3rd nibble.

2 Retrieve encoded MAC address from 24C16 serial 2-wire EEPROM,
3 decode it and store it in the associated adapter struct for
4 use by dvb_net.c
5
6 This card appear to have the 24C16 write protect held to ground,
7 thus permitting normal read/write operation. Theoretically it
8 would be possible to write routines to burn a different (encoded)
9 MAC address into the EEPROM.
