The current code was trying to query the AC97 registers for the vendor information even if it was clearly not a AC97 audio device (resulting in errors in the dmesg output). This was due to a bug in the way we did the check. Signed-off-by: NDevin Heitmueller <dheitmueller@linuxtv.org> Signed-off-by: NMauro Carvalho Chehab <mchehab@redhat.com>

Like the em2874, the em2870 does not have any analog support, so don't bother loading the em28xx-alsa module. Signed-off-by: NDevin Heitmueller <dheitmueller@linuxtv.org> Signed-off-by: NMauro Carvalho Chehab <mchehab@redhat.com>

em28xx-video were holding several code that are not specific to V4L2 interface. This patch moves the core code for em28xx-core, and usb probing code into em28xx-cards. This opens the possibility of breaking em28xx into a core module and a V4L2 module, loaded only on devices that have analog interfaces. Some cleanup may be done at em28xx-cards to optimize the config code. Signed-off-by: NMauro Carvalho Chehab <mchehab@redhat.com>

Replaces all occurrences of em28xx_write_regs_req() and em28xx_write_reg() used to setup register names by em28xx_write_reg(). Also, documents the register names that are known. This patch were generated by this small perl script: my %reg_map = ( # Register table - the same as defined on parse_em28xx.pl script ); while (<>) { if (m/(.*)em28xx_write_regs_req\(dev\,\s*0x00\,\s*(.*)\,\s*\"\\x(..)\",\s*1\)\;(.*)/) { my $reg = $2; my $val = $3; $val =~ tr/A-f/a-f/; $reg = $reg_map{$reg} if defined($reg_map{$reg}); printf "$1em28xx_write_reg(dev, %s, 0x%s);$4\n", $reg, $val; } elsif (m/(.*)em28xx_write_regs\(dev\,\s*(.*)\,\s*\"\\x(..)\",\s*1\)\;(.*)/) { my $reg = $2; my $val = $3; $val =~ tr/A-f/a-f/; $reg = $reg_map{$reg} if defined($reg_map{$reg}); printf "$1em28xx_write_reg(dev, %s, 0x%s);$4\n", $reg, $val; } else { print $_; } } Signed-off-by: NMauro Carvalho Chehab <mchehab@redhat.com>

Several fields are duplicated on both structs. Let's just copy em28xx_board instead. A later cleanup could just copy the fields that are changed, in order to keep em28xx_board const. Signed-off-by: NMauro Carvalho Chehab <mchehab@redhat.com>

The previous patches removed XCLK and I2C magic. Now, we finally know what those registers do. Also, only a very few cards need different setups for those. Instead of keeping the setups for those values inside the per-device hack magic switch, move the uncommon values to the board-specific struct, and have a common setup for all other boards. So, almost 100 lines of hacking magic were removed. A co-lateral effect of this patch is that it also fixes a bug at em28xx-core, where xclk were set, without taking any care about not overriding a previous xclk setup.

AC97 devices provide several input and outputs. However, before this patch, em28xx device weren't properly allowing the usage of ac97 possible combinations. Also, several input volumes were left untouched, instead of making sure that the volumes were set on mute state. This patch improves support for ac97 devices by allowing to use any inputs, and making sure that unused inputs are set on mute state. Yet, some work is still needed to select the AC97 output.

This patch properly implements audio handling on em28xx. Before this patch, it was assumed that every device has an Empia 202 audio chip. However, this is not true.

Now that we have a polling task for IR, there's a race condition, since IR can be polling while other operations are being doing. Also, we are now sharing the same urb_buf for both read and write control urb operations. So, we need a mutex. Thanks to Davin Heitmueller <devin.heitmueller@gmail.com> for warning me.

Before this patch, every register setup on em28xx were dynamically allocating a temporary buffer for control URB's to be handled. To avoid this ping-pong, use, instead a pre-allocated buffer. Also, be sure that read control URB's also use the buffer, instead of relying on a stack buffer. Signed-off-by: NMauro Carvalho Chehab <mchehab@redhat.com>

Before this patch, HVR900/HVR950 were incorreclty going back to analog. The result is that only digital were working. This patch provides the proper setup for analog/digital and tuner callback. It also properly resets analog into a sane state at open().

Now, all registers will follow the same convension: EM28XX_R<reg_number>_<reg_name> This allows to associate a register with its value, and also with a canonical name. Also, registers that are specific to a given chip were renamed accordingly, as EM2800_foo (for 2800 only registers) or EM2880_foo (for registers that started to appear on em2880).

The usage of videobuf-vmalloc allows to cleanup em28xx logic. Also, it reduced its size by about 5.42% on i386 arch (and about 7.5% on x86_64): 39113 4876 40 44029 abfd old/em28xx.ko 36731 4868 40 41639 a2a7 /home/v4l/master/v4l/em28xx.ko Also, the preliminary tests, made on a single core 1.5 MHz Centrino showed that CPU usage reduced from 42%-75% to 28%-33% (reports from "top") command. A test with time command presented an even better result: This is the performance tests I did, running code_example to get 1,000 frames @29.995 Hz (about 35 seconds of stream), tested on a i386 machine, running at 1,5GHz: The old driver: $ time -f "%E: %Us User time, %Ss Kernel time, %P CPU used" ./capture_example 0:34.21: 8.22s User time, 25.16s Kernel time, 97% CPU used The videobuf-based driver: $ time -f "%E: %Us User time, %Ss Kernel time, %P CPU used" ./capture_example 0:35.36: 0.01s User time, 0.05s Kernel time, 0% CPU used Conclusion: The time consumption to receive the stream where reduced from about 33.38 seconds to 0.05 seconds.
