cx18: Move DVB buffer transfer handling from irq handler to work_queue thread. In order to properly lock the epu2cpu mailbox for driver to CX23418 commands, the DVB/TS buffer handling needs to be moved from the IRQ handler and IRQ context to a work queue. This work_queue implmentation is strikingly similar to the ivtv implementation - for better or worse.

cx18: Use correct Mailbox IRQ Ack values and misc IRQ handling cleanup. The SCB field definitions for Ack IRQ's for mailboxes were inconsistent with the bitmasks being loaded into those SCB fields and the SW2 Ack IRQ handling logic. Renamed fields in SCB to make things consistent and did misc IRQ handling cleanups: removing legacy ivtv dma_reg_lock, HPU IRQ flags, etc. Signed-off-by: Andy Walls <awalls@radix.net> Signed-off-by: Mauro Carvalho Chehab <mchehab@redhat.com>

cx18: Mark CX18_CPU_DE_RELEASE_MDL as a slow API call. Give the encoder time to complete the MDL release before destroying the encoder internal task.

When inadvertently hot-unplugging a WT-220U USB DVB-T receiver with 2.6.24, I was met with an oops [1]. The problem is relevant to 2.6.25/26-rc also. dvb_frontend_init() was called either from re-creation of the kdvb-fe0 thread - seems unlikely, or someone called dvb_frontend_reinitialise(), causing this path in the thread - really unlikely, as I can't find any call-site for it. Either way, quite a number of drivers call dvb_usb_generic_rw() [2] without checking the validity of the relevant member in the dvb_usb_device struct - which had changed. Having dvb_usb_generic_rw() sanity-check and fail (rather than loading from 0x120) seems reasonable defensive programming [3], in light of it being called in this way. The problem with this, is that drivers don't check the return code of the init call [4]. Does it make sense to cook a patch which allows the failure to be propagated back up, or am I missing something else? Thanks, Daniel <whoops, hot unplug> [83711.538485] dvb-usb: bulk message failed: -71 (1/0) [83711.538875] dvb-usb: bulk message failed: -71 (1/0) [83711.538899] usb 7-5: USB disconnect, address 3 [83711.538905] dvb-usb: bulk message failed: -22 (1/0) [83711.538924] dvb-usb: bulk message failed: -22 (1/0) [83711.538943] dvb-usb: bulk message failed: -22 (1/0) [83711.588979] dvb-usb: bulk message failed: -22 (1/0) [83711.589031] dvb-usb: bulk message failed: -22 (1/0) [83711.589078] dvb-usb: bulk message failed: -22 (1/0) [83711.589122] dvb-usb: bulk message failed: -22 (1/0) [83711.589167] dvb-usb: bulk message failed: -22 (1/0) [83711.639233] dvb-usb: bulk message failed: -22 (1/0) [83711.639282] dvb-usb: bulk message failed: -22 (1/0) [83711.639330] dvb-usb: bulk message failed: -22 (1/0) [83711.639374] dvb-usb: bulk message failed: -22 (1/0) [83711.639421] dvb-usb: bulk message failed: -22 (1/0) [83711.658391] dvb-usb: bulk message failed: -22 (1/0) [83768.174281] dvb-usb: bulk message failed: -22 (2/-32512) [83768.174350] Unable to handle kernel NULL pointer dereference<6>dvb-usb: WideView WT-220U PenType Receiver (Typhoon/Freecom) successfully deinitialized and disconnected.

ivtv used tvaudio in the past and at the time tvaudio required V4L1.

cx18: Disable write retries for registers that always change - part 1. Interrupt related registers will likely not read back the value we just wrote. Disable retries for these registers for now to avoid accidently discarding interrupts.

There already is an report at kernel bugzilla about this issue: http://bugzilla.kernel.org/show_bug.cgi?id=9455 When enabling extra checks for the i2c-bus of cx88 based cards by loading i2c_algo_bit with bit_test=1 this may trigger an oops when loading cx88_dvb. This is caused by the extra check code that detects that the sda-line is stuck high and thus does not register the i2c-bus. cx88-dvb however does not check if the i2c-bus is valid and just uses core->i2c_adap to attach dvb frontend modules. This leads to an oops at the first call to i2c_transfer: $ modprobe i2c_algo_bit bit_test=1 $ modprobe cx8802 cx88/2: cx2388x MPEG-TS Driver Manager version 0.0.6 loaded cx88[0]: quirk: PCIPCI_NATOMA -- set TBFX cx88[0]: subsystem: 0070:9202, board: Hauppauge Nova-S-Plus DVB-S [card=37,autodetected], frontend(s): 1 cx88[0]: TV tuner type 4, Radio tuner type -1 cx88[0]: SDA stuck high! cx88[0]: i2c register FAILED input: cx88 IR (Hauppauge Nova-S-Plus as /class/input/input5 cx88[0]/2: cx2388x 8802 Driver Manager cx88-mpeg driver manager 0000:00:10.2: enabling device (0154 -> 0156) cx88-mpeg driver manager 0000:00:10.2: PCI INT A -> Link[LNKD] -> GSI 9 (level, low) -> IRQ 9 cx88[0]/2: found at 0000:00:10.2, rev: 5, irq: 9, latency: 64, mmio: 0xfb000000 cx8802_probe() allocating 1 frontend(s) cx88/2: cx2388x dvb driver version 0.0.6 loaded cx88/2: registering cx8802 driver, type: dvb access: shared cx88[0]/2: subsystem: 0070:9202, board: Hauppauge Nova-S-Plus DVB-S [card=37] cx88[0]/2: cx2388x based DVB/ATSC card BUG: unable to handle kernel NULL pointer dereference at 00000000 IP: [<e084d4ef>] :i2c_core:i2c_transfer+0x1f/0x80 *pde = 00000000 Modules linked in: cx88_dvb(+) cx8802 cx88xx ir_common i2c_algo_bit tveeprom videobuf_dvb btcx_risc mga drm ipv6 fscpos eeprom nfsd exportfs stv0299 b2c2_flexcop_pci b2c2_flexcop cx24123 s5h1420 ves1x93 dvb_ttpci dvb_core saa7146_vv saa7146 videobuf_dma_sg videobuf_core videodev v4l1_compat ttpci_eeprom lirc_serial lirc_dev usbhid rtc uhci_hcd 8139too i2c_piix4 i2c_core usbcore evdev Pid: 4249, comm: modprobe Not tainted (2.6.27-gentoo #3) EIP: 0060:[<e084d4ef>] EFLAGS: 00010296 CPU: 0 EIP is at i2c_transfer+0x1f/0x80 [i2c_core] EAX: 00000000 EBX: ffffffa1 ECX: 00000002 EDX: d6c71e3c ESI: d80cd050 EDI: d8093c00 EBP: d6c71e20 ESP: d6c71e0c DS: 007b ES: 007b FS: 0000 GS: 0033 SS: 0068 Signed-off-by: Mauro Carvalho Chehab <mchehab@redhat.com>

Impact: driver could possibly stomp on resources outside of its scope {mchehab@redhat.com: I got two versions of the same patch (identical, except for whitespacing). One authored by Andy Burns and another authored by Suresh Siddha. Due to that, I'm applying the one that has less CodingStyle errors. I'm also adding both comments and the SOB's for both patches, since they are both interesting} Suresh Siddha commented: Alexey Fisher reported: > resource map sanity check conflict: 0xcfeff800 0xcff007ff 0xcfe00000 > 0xcfefffff PCI Bus 0000:01 BAR base is located in the middle of the 4K page and the hardcoded size argument makes the request span two pages causing the conflict. Fix the hard coded size argument in ioremap(). Andy Burns commented: I have already sent this patch on the linux-dvb list, but it didn't get much attention, so re-sending direct, I hope you all don't mind. While attempting to run mythtv in a xen domU, I encountered problems loading the driver for my saa7134 card, with an error from ioremap(). This error was due to the driver allocating an incorrectly sized mmio area, which was trapped by xen's permission checks, but this would go un-noticed on a kernel without xen. My card has a 1K sized mmio area, I've had information that other cards have 2K areas, perhaps others have different sizes, yet the driver always attempts to map 4K. I realise that the granularity of mapping is the page size, which typically would be 4K, but unless the card's base address happens to fall on a 4K boundary (mine does not) then the base+4K will end up spanning two pages, and this is when the error occurs under xen. My patch uses the pci_resource_len macro to determine the size required for the user's particular card, instead of the hardcoded 4K value. I've tested with a couple of printk() inside ioremap() that the start address and size do get rounded to the closest page boundary. With this patch I am able to successfully load the saa7134 driver and run mythtv under xen with my card, subject to correct pollirq settings in case of shared IRQ, I am still seeing occasional DMA panics, which I think are related to swiotlb handling by dom0/domU, usually the panic occurs when changing mux, once tuned to a mux, 12 hour continuous recordings are possible without errors.

Remove lock_kernel() call from cafe_ccic.c Commit d56dc612 added lock_kernel() calls to cafe_ccic.c. But that driver was written with proper locking and does not need the BKL, so take it back out.

Due to that, an OOPS is generated at dev_info. This patch replaces uvd->dev->dev to dev->dev inside this routine.

rather than implementing different ways leading to confusion. This allows multiple gate_enable/disable's in the tuner_read/write functions, thereby lesser number of I/O operations throughout, eventually leading to better results. As a side effect demods that detect the STOP bit for auto closing of the gate can be avoided, thereby a very minimal gain in disabling the auto detect feature as well. Improves readability on the device control. Signed-off-by: Manu Abraham <manu@linuxtv.org> Signed-off-by: Mauro Carvalho Chehab <mchehab@redhat.com>
