* | V4L/DVB (10694): [PATCH] software IRQ watchdog for Flexcop B2C2 DVB PCI cardsPatrick Boettcher2009-02-273-25/+44
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | With (some) Technisat cards you cannot run multiple DVB applications in parallel and switch the channel at the same time. There seems to be a problem on the interfaces or even inside the flexcop-device that can't handle interruption on the streaming interface. This patch adds a watchdog to check whether data is supposed to come in (streaming PIDs are requested) and if no data is seen within 400ms (default) it resets the streaming/pid-filtering hardware. This patch is urgently needed to support the rev 2.8 of the hardware and solves problem occassionally seen on older hardware.

* | V4L/DVB (10659): em28xx: register device to soundcard for sysfsNicola Soranzo2009-02-271-0/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | As explained in "Writing an ALSA driver" (T. Iwai), audio drivers should set the struct device for the card before registering the card instance. This will add the correct /sys/class/sound/cardN/device symlink, so HAL can see the device and ConsoleKit sets its ACL permissions for the logged-in user. For em28xx audio capture cards found e.g. in Hauppauge WinTV-HVR-900 (R2), this patch fixes errors like: ALSA lib pcm_hw.c:1429:(_snd_pcm_hw_open) Invalid value for card Error opening audio: Permission denied when running mplayer as a normal user.

* | firedtv: dvb_frontend_info for FireDTV S2, fix "frequency limits undefined" ↵Beat Michel Liechti2009-02-241-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | error I found that the function fdtv_frontend_init in the file firedtv-fe.c was missing a case for FIREDTV_DVB_S2 which resulted in "frequency limits undefined" errors in syslog. Signed-off-by: Beat Michel Liechti <bml303@gmail.com> Change by Stefan R: combine it with case case FIREDTV_DVB_S as originally suggested by Beat Michel. This enables FE_CAN_FEC_AUTO also for FireDTV-S2 devices which is possible as long as only DVB-S channels are used. FE_CAN_FEC_AUTO would be wrong for DVB-S2 channels, but those cannot be used yet since the driver is not yet converted to S2API. Signed-off-by: Stefan Richter <stefanr@s5r6.in-berlin.de>

So bring it back in an updated form with only 60% of the original code footprint. Logging can be enabled with # echo -1 > /sys/module/firedtv/parameters/debug 1 instead of -1 enables only FCP header logging, 2 instead of -1 enables only hexdumps of the entire FCP frames. 0 switches logging off again. Fri, 20 Feb 2009 20:54:27 +0100 (CET) firedtv: build fix for INPUT=m and DVB_FIREDTV=y Thu, 19 Feb 2009 20:40:39 +0100 firedtv: use msecs_to_jiffies Pointed out by Mauro Carvalho Chehab. Sun Feb 15 20:50:46 CET 2009 firedtv: some more housekeeping Fix an old checkpatch warning and a new compiler warning. Sun Feb 15 15:33:17 CET 2009 firedtv: rename a file once more At the moment, about a third of avc.c is specific to FireDTVs rather than generic AV/C code. Rename it to firedtv-avc.c. Sun Feb 15 15:33:17 CET 2009 firedtv: dvb demux: more compact channels backing store Replace struct firedtv_channel { bool active; int pid; } channel[16]; by unsigned long channel_active; u16 channel_pid[16];. Sun Feb 15 15:33:17 CET 2009 firedtv: dvb demux: some simplifications c->active was unnecessarily cleared twice. Also, by marking the channel inactive before the for loop, the loop becomes identical with fdtv_channel_collect(). Sun Feb 15 15:33:17 CET 2009 firedtv: dvb demux: remove a bogus loop This loop is unnecessary because - only active channel[].pid's will be sent to the device, - when a channel is activated, its pid is set to dvbdmxfeed->pid. Perhaps the original code was there because it was initially not fully covered by the fdtv->demux_mutex. Sun Feb 15 15:33:17 CET 2009 firedtv: dvb demux: fix mutex protection fdtv_start_feed() accessed the channel list unsafely. Fully serialize it with itself and fdtv_stop_feed(). Sun Feb 15 15:33:17 CET 2009 firedtv: dvb demux: fix missing braces Original code was: ... case DMX_TS_PES_OTHER: //Dirty fix to keep firesat->channel pid-list up to date for(k=0;k<16;k++){ if(firesat->channel[k].active == 0) firesat->channel[k].pid = dvbdmxfeed->pid; break; } channel = firesat_channel_allocate(firesat); break; default: ... Looks bogus in several respects. For now let's just add braces to the if because that seems to be what the author meant. Sun Feb 15 15:33:17 CET 2009 firedtv: allow build without input subsystem !CONFIG_INPUT is very unlikely on systems on which firedtv is of interest. But we can easily support it. Sun Feb 15 15:33:17 CET 2009 firedtv: replace EXTRA_CFLAGS by ccflags The former are deprecated. The latter can depend on Kconfig variables. Sun Feb 15 15:33:17 CET 2009 firedtv: concentrate ieee1394 dependencies Move the entire interface with drivers/ieee1394 to firedtv-1394.c. Move 1394-independent module initialization code to firedtv-dvb.c. This prepares interfacing with drivers/firewire. Sun Feb 15 15:33:17 CET 2009 firedtv: amend Kconfig menu prompt Sun Feb 15 15:33:17 CET 2009 firedtv: remove kernel version compatibility macro Sun Feb 15 15:33:17 CET 2009 firedtv: combine header files avc.h and firedtv-*.h are small and currently not shared with other drivers, hence concatenate them all into firedtv.h. Sun Feb 15 15:33:17 CET 2009 firedtv: misc style touch-ups Standardize on lower-case hexadecimal constants. Adjust whitespace. Omit unnecessary pointer type casts and an unnecessary list head initialization. Use dev_printk. Wed Feb 11 21:21:04 CET 2009 firedtv: avc, ci: remove unused constants Wed Feb 11 21:21:04 CET 2009 firedtv: avc: remove bitfields from read descriptor response operands Don't use bitfields in struct types of on-the-wire data. Wed Feb 11 21:21:04 CET 2009 firedtv: avc: remove bitfields from DSD command operands Don't use bitfields in struct types of on-the-wire data. Wed Feb 11 21:21:04 CET 2009 firedtv: avc: header file cleanup Remove unused constants and declarations. Move privately used constants into .c files. Wed Feb 11 21:21:04 CET 2009 firedtv: avc: remove bitfields from FCP frame types Don't use bitfields in struct types of on-the-wire data. Also move many privately used constants from avc.h to avc.c and remove some unused constants. Sun, 18 Jan 2009 16:30:00 +0100 (CET) firedtv: avc: fix offset in avc_tuner_get_ts The parentheses were wrong. It didn't matter though because this code only writes a 0 into an area which is already initialized to 0. Sun, 18 Jan 2009 16:30:00 +0100 (CET) firedtv: avc: reduce stack usage, remove two typedefs It is safe to share a memory buffer for command frame and response frame because the response data come in after the command frame was last used. Even less stack would be required if only the actual required frame size instead of the entire FCP register size was allocated. Also, rename the defined types AVCCmdFrm and AVCRspFrm to struct avc_command_frame and struct avc_response_frame. TODO: Remove the bitfields in these types. Sun, 18 Jan 2009 16:30:00 +0100 (CET) firedtv: cmp: move code to avc Sun, 18 Jan 2009 16:30:00 +0100 (CET) firedtv: iso: move code to firedtv-1394 Sun, 18 Jan 2009 16:30:00 +0100 (CET) firedtv: iso: remove unnecessary struct type definitions Sun, 18 Jan 2009 16:30:00 +0100 (CET) firedtv: iso: style changes and fixlets Add cleanup after failure in setup_iso_channel.

Effect of the fix not yet tested. Sun, 2 Nov 2008 13:45:00 +0100 (CET) firedtv: replace mdelay by msleep These functions can sleep (and in fact sleep for the duration of a whole FCP transaction). Hence msleep is more appropriate here. Sun, 2 Nov 2008 13:45:00 +0100 (CET) firedtv: trivial reorganization in avc_api Reduce nesting level by factoring code out of avc_tuner_dsd() into helper functions. Sun, 2 Nov 2008 13:45:00 +0100 (CET) firedtv: trivial cleanups in avc_api Use dev_err(), no CamelCase function names, adjust comment style, put #if 0 around unused code and add FIXME comments, standardize on lower-case hexadecimal constants, use ALIGN() for some frame length calculations, make a local function static... The code which writes FCP command frames and reads FCP response frames is not yet brought into canonical kernel coding style because this involves changes of typedefs (on-the-wire bitfields). Sun, 2 Nov 2008 13:45:00 +0100 (CET) firedtv: don't retry oPCR updates endlessly In the theoretical case that the target node wasn't handling the lock transactions as expected or there was continued interference by other initiating nodes, these functions wouldn't return for ages. Sun, 2 Nov 2008 13:45:00 +0100 (CET) firedtv: remove bitfield typedefs from cmp, fix for big endian CPUs Use macros/ inline functions/ standard byte order accessors to read and write oPCR register values (big endian bitfields, on-the-wire data). The new code may not be the ultimate optimum, but it doesn't occur in a hot path. This fixes the CMP code for big endian CPUs. So far I tested it only on a little endian CPU though. For now, include <asm/byteorder.h> instead of <linux/byteorder.h> because drivers/ieee1394/*.h also include the former. I will fix this in drivers/ieee1394 and firedtv later. Sun, 2 Nov 2008 13:45:00 +0100 (CET) firedtv: trivial cleanups in cmp Reduce nesting level by means of early exit and goto. Remove obsolete includes, use dev_err(), no CamelCase function names... Sun, 2 Nov 2008 13:45:00 +0100 (CET) firedtv: trivial cleanups in firesat-ci Whitespace, variable names, comment style... Also, use dvb_generic_open() and dvb_generic_release() directly as our hooks in struct file_operations because firedtv's wrappers merely called these generic functions. Sun, 2 Nov 2008 13:45:00 +0100 (CET) firedtv: remove CA debug code This looks like it is not necessary to have available for endusers who cannot patch kernels for bug reporting and tests of fixes. Sun, 2 Nov 2008 13:45:00 +0100 (CET) firedtv: remove AV/C debug code This looks like it is not necessary to have available for endusers who cannot patch kernels for bug reporting and tests of fixes. Sun, 2 Nov 2008 13:45:00 +0100 (CET) firedtv: remove various debug code Most of this was already commented out. And that which wasn't is not relevant in normal use. Mon, 29 Sep 2008 19:22:48 +0200 (CEST) firedtv: register input device as child of a FireWire device Instead of one virtual input device which exists for the whole lifetime of the driver and receives events from all connected FireDTVs, register one input device for each firedtv device. These input devices will show up as children of the respective firedtv devices in the sysfs hierarchy. However, the implementation falls short because of a bug in userspace: Udev's path_id script gets stuck with 100% CPU utilization, maybe because of an assumption about the maximum ieee1394 device hierarchy depth. To avoid this bug, we use the fw-host device instead of the proper unit_directory device as parent of the input device. There is hope that the port to the new firewire stack won't be inhibited by this userspace bug because there are no fw-host devices there. Mon, 29 Sep 2008 19:21:52 +0200 (CEST) firedtv: fix string comparison and a few sparse warnings Sparse found a bug: while ((kv_buf + kv_len - 1) == '\0') should have been while (kv_buf[kv_len - 1] == '\0') We fix it by a better implementation without a temporary copy. Also fix sparse warnings of 0 instead of NULL and signedness mismatches. Mon, 29 Sep 2008 19:21:20 +0200 (CEST) firedtv: remove unused struct members and redefine an int as a bool. Mon, 29 Sep 2008 19:20:36 +0200 (CEST) firedtv: fix initialization of dvb_frontend.ops There was a NULL pointer reference if no dvb_frontend_info was found. Also, don't directly assign struct typed values to struct typed variables. Instead write out assignments to individual strcut members. This reduces module size by about 1 kB. Mon, 29 Sep 2008 19:19:41 +0200 (CEST) firedtv: remove unused dual subunit code from initialization No FireDTVs with more than one subunit exists, hence simplify the initialization for the special case of one subunit. The driver was able to check for more than one subunit but was broken for more than two subunits. While we are at it, add several missing cleanups after failure, and include a few dynamically allocated structures diretly into struct firesat instead of allocating them separately. Mon, 29 Sep 2008 19:19:08 +0200 (CEST) firedtv: add vendor_id and version to driver match table Now that nodemgr was enhanced to match against the root directory's vendor ID if there isn't one in the unit directory, use this to prevent firedtv to be bound to wrong devices by accident. Also add the AV/C software version ID to the match flags for completeness; specifier ID and software only make sense as a pair. Mon, 29 Sep 2008 19:18:30 +0200 (CEST) firedtv: use hpsb_node_read(), _write(), _lock() because they are simpler and treat the node generation more correctly.

Per default, various media key keycodes are emitted which closely match what is printed on the remote. Userland can modify the mapping by means of evdev ioctls. (Not tested.) The old scancode-to-keycode mapping is left in the driver but cannot be modified by ioctls. This preserves status quo for old remotes. Tue, 26 Aug 2008 00:11:28 +0200 (CEST) firedtv: replace tasklet by workqueue job Non-atomic context is a lot nicer to work with. Sun, 24 Aug 2008 23:30:00 +0200 (CEST) firedtv: move some code back to ieee1394 core Partially reverts "ieee1394: remove unused code" of Linux 2.6.25. Sun, 24 Aug 2008 23:29:30 +0200 (CEST) firedtv: replace semaphore by mutex firesat->avc_sem and ->demux_sem have been used exactly like a mutex. The only exception is the schedule_remotecontrol tasklet which did a down_trylock in atomic context. This is not possible with mutex_trylock; however the whole remote control related code is non-functional anyway at the moment. This should be fixed eventually, probably by turning the tasklet into a worqueue job. Convert everything else from semaphore to mutex. Also rewrite a few of the affected functions to unlock the mutex at a single exit point, instead of in several branches. Sun, 24 Aug 2008 23:28:45 +0200 (CEST) firedtv: some header cleanups Unify #ifndef/#define/#endif guards against multiple inclusion. Drop extern keyword from function declarations. Remove #include's into header files where struct declarations suffice. Remove unused ohci1394 interface and related unused ieee1394 interfaces. Add a few missing #include's and remove a few apparently obsolete ones. Sort them alphabetically. Sun, 24 Aug 2008 23:27:45 +0200 (CEST) firedtv: nicer registration message and some initialization fixes Print the correct name in dvb_register_adapter(). While we are at it, replace two switch cascades by one for loop, remove a superfluous member of struct firesat and of two unused arguments of AVCIdentifySubunit(), and fix bogus kfree's in firesat_dvbdev_init(). Tue, 26 Aug 2008 14:24:17 +0200 (CEST) firesat: rename to firedtv Suggested by Andreas Monitzer. Besides DVB-S/-S2 receivers, the driver also supports DVB-C and DVB-T receivers, hence the previous project name is too narrow now. Not yet done: Rename source directory, files, types, variables...

The implementation is a bare minimum to get encrypted channels to work in kaffeine. It works fine with my T/CI card. Now and then I get an AVC timeout and have to retune a channel in order to get it to work. Once the CAM seemed to hang so I needed to remove and insert it again. I.e. there are a number of glitches. The latest version contains the following changes: - Implemented the new hpsb iso interface so that data can be received from the card - Reduced some timers for demux setup which caused scanning to timeout - Added possibility to unload driver - Added support for getting C/N ratio - Added two debug parameters to the driver; ca_debug and avc_comm_debug. - Added CI support that works for me in kaffeine - Started working on CI MMI support.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | As reported by David Engel <david@istwok.net>, ATSC115 doesn't work fine with mythtv. This software opens both analog and dvb interfaces of saa7134. What happens is that some tuner commands are going to the wrong place, as shown at the logs: Feb 12 20:37:48 opus kernel: tuner-simple 1-0061: using tuner params #0 (ntsc) Feb 12 20:37:48 opus kernel: tuner-simple 1-0061: freq = 67.25 (1076), range = 0, config = 0xce, cb = 0x01 Feb 12 20:37:48 opus kernel: tuner-simple 1-0061: Freq= 67.25 MHz, V_IF=45.75 MHz, Offset=0.00 MHz, div=1808 Feb 12 20:37:48 opus kernel: tuner 1-0061: tv freq set to 67.25 Feb 12 20:37:48 opus kernel: tuner-simple 1-000a: using tuner params #0 (ntsc) Feb 12 20:37:48 opus kernel: tuner-simple 1-000a: freq = 67.25 (1076), range = 0, config = 0xce, cb = 0x01 Feb 12 20:37:48 opus kernel: tuner-simple 1-000a: Freq= 67.25 MHz, V_IF=45.75 MHz, Offset=0.00 MHz, div=1808 Feb 12 20:37:48 opus kernel: tuner-simple 1-000a: tv 0x07 0x10 0xce 0x01 Feb 12 20:37:48 opus kernel: tuner-simple 1-0061: tv 0x07 0x10 0xce 0x01 This happens due to a hack at TUV1236D analog setup, where it replaces tuner address, at 0x61 for 0x0a, in order to save a few memory bytes. The code assumes that nobody else would try to access the tuner during that setup, but the point is that there's no lock to protect such access. So, this opens the possibility of race conditions to happen. Instead of hacking tuner address, this patch uses a temporary var with the proper tuner value to be used during the setup. This should save the issue, although we should consider to write some analog/digital lock at saa7134 driver. Signed-off-by: Mauro Carvalho Chehab <mchehab@redhat.com>

I've recently experienced the following fairly consistent kernel oops on startup in grundig_29504_401_tuner_set_params from budget.c. As you might expect, following this failure, the card doesn't work. I'm not a kernel developer, nevertheless I seem to have managed to track this down to a non-existent initialisation of budget->dvb_frontend->tuner_priv. The attached patch fixes the problem for me (and I've managed to tune the card successfully as a result), but I don't know of anyone else using the driver so I can't test it on other people. Please let me know if this works for you or if I've done something terribly wrong ;-( BUG: unable to handle kernel paging request at ffffffff IP: [<f8981e11>] :budget:grundig_29504_401_tuner_set_params+0x3b/0xf8 *pde = 007e0067 *pte = 00000000 Oops: 0000 [#1] SMP Modules linked in: bridge stp bnep rfcomm l2cap asb100 hwmon_vid hwmon fuse ipt_REJECT nf_conntrack_ipv4 iptable_filter ip_tables ip6t_REJECT xt_tcpudp nf_conntrack_ipv6 xt_state nf_conntrack ip6table_filter ip6_tables x_tables ipv6 loop dm_multipath scsi_dh ppdev snd_cmipci gameport snd_seq_dummy snd_seq_oss snd_seq_midi_event snd_seq snd_pcm_oss snd_mixer_oss l64781 snd_pcm snd_page_alloc snd_opl3_lib snd_timer parport_pc snd_hwdep parport btusb snd_mpu401_uart budget budget_core snd_rawmidi bluetooth saa7146 snd_seq_device ttpci_eeprom snd soundcore sr_mod i2c_sis96x cdrom dvb_core sis900 i2c_core floppy pcspkr mii sata_sil sg dm_snapshot dm_zero dm_mirror dm_log dm_mod pata_sis ata_generic pata_acpi libata sd_mod scsi_mod crc_t10dif ext3 jbd mbcache uhci_hcd ohci_hcd ehci_hcd [last unloaded: microcode] Pid: 2319, comm: kdvb-fe-0 Not tainted (2.6.27.9-73.fc9.i686 #1) EIP: 0060:[<f8981e11>] EFLAGS: 00010286 CPU: 0 EIP is at grundig_29504_401_tuner_set_params+0x3b/0xf8 [budget] EAX: f6417f00 EBX: f6f53808 ECX: 00000000 EDX: ffffffff ESI: f6f94404 EDI: f6417f00 EBP: f6417f10 ESP: f6417ef0 DS: 007b ES: 007b FS: 00d8 GS: 0000 SS: 0068 Process kdvb-fe-0 (pid: 2319, ti=f6417000 task=f642b2c0 task.ti=f6417000) Stack: f6e39800 00000000 00000004 f6417f00 c064523c f6f53808 f6f53800 f6f94404 f6417f54 f8b2e45a f6417f24 00000286 f6417f4c f6417f38 00000000 00000286 f6417f3c c064520f f642b2c0 f6417f6c c064456f 00000001 f6f94400 00000001 Call Trace: [<c064523c>] ? _spin_lock_irqsave+0x29/0x30 [<f8b2e45a>] ? apply_frontend_param+0x27/0x357 [l64781] [<c064520f>] ? _spin_lock_irq+0x1c/0x20 [<c064456f>] ? __down_common+0x91/0xbf [<f894f25d>] ? dvb_frontend_swzigzag_autotune+0x17d/0x1a4 [dvb_core] [<f894f780>] ? dvb_frontend_swzigzag+0x1ac/0x209 [dvb_core] [<f894fcc8>] ? dvb_frontend_thread+0x2eb/0x3b3 [dvb_core] [<c043c166>] ? autoremove_wake_function+0x0/0x33 [<f894f9dd>] ? dvb_frontend_thread+0x0/0x3b3 [dvb_core] [<c043bec3>] ? kthread+0x3b/0x61 [<c043be88>] ? kthread+0x0/0x61 [<c040494b>] ? kernel_thread_helper+0x7/0x10 ======================= Code: ec 14 8b 80 00 02 00 00 8b 93 08 02 00 00 8d 7d e4 8b 40 20 89 45 e0 31 c0 85 d2 f3 ab 8d 45 f0 66 c7 45 e8 04 00 89 45 ec 74 09 <0f> b6 02 66 89 45 e4 eb 06 66 c7 45 e4 61 00 8b 0e be 0a 8b 02 EIP: [<f8981e11>] grundig_29504_401_tuner_set_params+0x3b/0xf8 [budget] SS:ESP 0068:f6417ef0 Signed-off-by: Oliver Endriss <o.endriss@gmx.de> Signed-off-by: Mauro Carvalho Chehab <mchehab@redhat.com>

| | | | | | | | | | | | | | | | | | | | | | Revert a change made in change 9743 which resulted in a kernel panic in some cases on shutdown of the audio stream. First discovered when working on the Pinnacle 880e support, and later reproduced by a user on the mailing list with the HVR-900 as well.
