2015-01-29[media] rc: sunxi-cir: Add support for the larger fifo found on sun5i and sun6iHans de Goede1-9/+12
Add support for the larger fifo found on sun5i and sun6i, having a separate compatible for the ir found on sun5i & sun6i also is useful if we ever want to add ir transmit support, because the sun5i & sun6i version do not have transmit support. Note this commits also adds checking for the end-of-packet interrupt flag (which was already enabled), as the fifo-data-available interrupt flag only gets set when the trigger-level is exceeded. So far we've been getting away with not doing this because of the low trigger-level, but this is something which we should have done since day one.

2014-12-23[media] rc-main: Re-apply filter for no-op protocol changeJames Hogan1-7/+7
Since commit da6e162d6a46 ("[media] rc-core: simplify sysfs code"), when the IR protocol is set using the sysfs interface to the same set of protocols that are already set, store_protocols() does not refresh the scancode filter with the new protocol, even if it has already called the change_protocol() callback successfully. This results in the filter being disabled in the hardware and not re-enabled until the filter is set again using sysfs. Fix in store_protocols() by still re-applying the filter whenever the change_protocol() driver callback succeeded. The problem can be reproduced with the img-ir driver by setting a filter, and then setting the protocol to the same protocol that is already set: $ echo nec > protocols $ echo 0xffff > filter_mask $ echo nec > protocols After this, messages which don't match the filter were still being received.

2014-12-04[media] img-ir/hw: Fix potential deadlock stopping timerJames Hogan2-3/+22
The end timer is used for switching back from repeat code timings when no repeat codes have been received for a certain amount of time. When the protocol is changed, the end timer is deleted synchronously with del_timer_sync(), however this takes place while holding the main spin lock, and the timer handler also needs to acquire the spin lock. This opens the possibility of a deadlock on an SMP system if the protocol is changed just as the repeat timer is expiring. One CPU could end up in img_ir_set_decoder() holding the lock and waiting for the end timer to complete, while the other CPU is stuck in the timer handler spinning on the lock held by the first CPU. Lockdep also spots a possible lock inversion in the same code, since img_ir_set_decoder() acquires the img-ir lock before the timer lock, but the timer handler will try and acquire them the other way around: ========================================================= [ INFO: possible irq lock inversion dependency detected ] 3.18.0-rc5+ #957 Not tainted --------------------------------------------------------- swapper/0/0 just changed the state of lock: (((&hw->end_timer))){+.-...}, at: [<4006ae5c>] _call_timer_fn+0x0/0xfc but this lock was taken by another, HARDIRQ-safe lock in the past: (&(&priv->lock)->rlock#2){-.....} and interrupts could create inverse lock ordering between them. other info that might help us debug this: Possible interrupt unsafe locking scenario: CPU0 CPU1 ---- ---- lock(((&hw->end_timer))); local_irq_disable(); lock(&(&priv->lock)->rlock#2); lock(((&hw->end_timer))); <Interrupt> lock(&(&priv->lock)->rlock#2); *** DEADLOCK *** This is fixed by releasing the main spin lock while performing the del_timer_sync() call.

2014-12-04[media] img-ir/hw: Always read data to clear bufferDylan Rajaratnam1-2/+4
A problem was found on Polaris where if the unit it booted via the power button on the infrared remote then the next button press on the remote would return the key code used to power on the unit. The sequence is: - The polaris powered off but with the powerdown controller (PDC) block still powered. - Press power key on remote, IR block receives the key. - Kernel starts, IR code is in IMG_IR_DATA_x but neither IMG_IR_RXDVAL or IMG_IR_RXDVALD2 are set. - Wait any amount of time. - Press any key. - IMG_IR_RXDVAL or IMG_IR_RXDVALD2 is set but IMG_IR_DATA_x is unchanged since the powerup key data was never read. This is worked around by always reading the IMG_IR_DATA_x in img_ir_set_decoder(), rather than only when the IMG_IR_RXDVAL or IMG_IR_RXDVALD2 bit is set.

2014-11-04[media] media/rc: Send sync space information on the lirc deviceAustin Lund1-3/+9
Userspace expects to see a long space before the first pulse is sent on the lirc device. Currently, if a long time has passed and a new packet is started, the lirc codec just returns and doesn't send anything. This makes lircd ignore many perfectly valid signals unless they are sent in quick sucession. When a reset event is delivered, we cannot know anything about the duration of the space.

2014-10-30[media] rc-core: fix protocol_change regression in ir_raw_event_registerTomas Melin2-1/+2
IR receiver using nuvoton-cir and lirc required additional configuration steps after upgrade from kernel 3.16 to 3.17-rcX. Bisected regression to commit da6e162d6a4607362f8478c715c797d84d449f8b ("[media] rc-core: simplify sysfs code"). The regression comes from adding function change_protocol in ir-raw.c. It changes behaviour so that only the protocol enabled by driver's map_name will be active after registration. This breaks user space behaviour, lirc does not get key press signals anymore. Enable lirc protocol by default for ir raw decoders to restore original behaviour.

Pull media updates from Mauro Carvalho Chehab: - new IR driver: hix5hd2-ir - the virtual test driver (vivi) was replaced by vivid, with has an almost complete set of features to emulate most v4l2 devices and properly test all sorts of userspace apps - the as102 driver had several bugs fixed and was properly split into a frontend and a core driver. With that, it got promoted from staging into mainstream - one new CI driver got added for CIMaX SP2/SP2HF (sp2 driver) - one new frontend driver for Toshiba ISDB-T/ISDB-S demod (tc90522) - one new PCI driver for ISDB-T/ISDB-S (pt3 driver) - saa7134 driver got support for go7007-based devices - added a new PCI driver for Techwell 68xx chipsets (tw68) - a new platform driver was added (coda) - new tuner drivers: mxl301rf and qm1d1c0042 - a new DVB USB driver was added for DVBSky S860 & similar devices - added a new SDR driver (hackrf) - usbtv got audio support - several platform drivers are now compiled with COMPILE_TEST - a series of compiler fixup patches, making sparse/spatch happier with the media stuff and removing several warnings, especially on those platform drivers that didn't use to compile on x86 - Support for several new modern devices got added - lots of other fixes, improvements and cleanups * tag 'media/v3.18-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/mchehab/linux-media: (544 commits) [media] ir-hix5hd2: fix build on c6x arch [media] pt3: fix DTV FE I2C driver load error paths Revert "[media] media: em28xx - remove reset_resume interface" [media] exynos4-is: fix some warnings when compiling on arm64 [media] usb drivers: use %zu instead of %zd [media] pci drivers: use %zu instead of %zd [media] dvb-frontends: use %zu instead of %zd [media] s5p-mfc: Fix several printk warnings [media] s5p_mfc_opr: Fix warnings [media] ti-vpe: Fix typecast [media] s3c-camif: fix dma_addr_t printks [media] s5p_mfc_opr_v6: get rid of warnings when compiled with 64 bits [media] s5p_mfc_opr_v5: Fix lots of warnings on x86_64 [media] em28xx: Fix identation [media] drxd: remove a dead code [media] saa7146: remove return after BUG() [media] cx88: remove return after BUG() [media] cx88: fix cards table CodingStyle [media] radio-sf16fmr2: declare some structs as static [media] radio-sf16fmi: declare pnp_attached as static ...
