Likewise, setting FIMC_REG_CITRGFMT_FLIP_Y_MIRROR bit causes Y-axis image flip (horizontal flip) and thus it corresponds to V4L2_CID_HFLIP. Currently the driver does X-axis flip when V4L2_CID_HFLIP is set and Y-axis flip for V4L2_CID_VFLIP. Fix this incorrect assignment by setting proper FIMC_REG_CITRGFMT register bits for ctx->hflip and ctx->vflip.

To differentiate between this platforms venc_type/vpbe_type was passed as part of platform data which was incorrect. The correct way to differentiate to handle this case is by passing different platform names. This patch creates platform_device_id[] array supporting different platforms and assigns id_table to the platform driver, and finally in the probe gets the actual device by using platform_get_device_id() and gets the appropriate driver data for that platform. Taking this approach will also make the DT transition easier.

So when we fall through to the 'err_gpio_request' label further down and call rc_free_device(rcdev) then that's a double free. Fix that by moving 'rcdev = NULL' from after the call to rc_free_device() to after rc_unregister_device(). That fixes the problem since rc_free_device() just does nothing if passed NULL and there's no further use of 'rcdev' after the call to rc_free_device() so it's not needed there.

If we'll look at gen_text(), in the inner loop, we'll see if (chr & (1 << (7 - i))) gen_twopix(dev, pos + j * dev->pixelsize, WHITE, (x+y) & 1); else gen_twopix(dev, pos + j * dev->pixelsize, TEXT_BLACK, (x+y) & 1); which calls gen_twopix() for every character pixel, and that is very expensive, because gen_twopix() branches several times. Now, let's note, that we operate on only two colors - WHITE and TEXT_BLACK, and that pixel for that colors could be precomputed and gen_twopix() moved out of the inner loop. Also note, that for black and white colors even/odd does not make a difference for all supported pixel formats, so we could stop doing that `odd` gen_twopix() parameter game. So the first thing we are doing here is 1) moving gen_twopix() calls out of gen_text() into vivi_fillbuff(), to pregenerate black and white colors, just before printing starts. what we have next is that gen_text's font rendering loop, even with gen_twopix() calls moved out, was inefficient and branchy, so let's 2) rewrite gen_text() loop so it uses less variables + unroll char horizontal-rendering loop + instantiate 3 code paths for pixelsizes 2,3 and 4 so that in all inner loops we don't have to branch or make indirections (*). Done all above reworks, for gen_text() we get nice, non-branchy streamlined code (showing loop for pixelsize=2): ? cmp $0x2,%eax ? ? jne 26 ? mov -0x18(%ebp),%eax ? mov -0x20(%ebp),%edi ? imul -0x20(%ebp),%eax ? movzwl 0x3ffc(%ebx),%esi 0,08 ? movzwl 0x4000(%ebx),%ecx 0,04 ? add %edi,%edi ? mov 0x0,%ebx 0,51 ? mov %edi,-0x1c(%ebp) ? mov %ebx,-0x14(%ebp) ? movl $0x0,-0x10(%ebp) ? lea 0x20(%edx,%eax,2),%eax ? mov %eax,-0x18(%ebp) ? xchg %ax,%ax 0,04 ? a0: mov 0x8(%ebp),%ebx ? mov -0x18(%ebp),%eax 0,04 ? movzbl (%ebx),%edx 0,16 ? test %dl,%dl 0,04 ? ? je 128 0,08 ? lea 0x0(%esi),%esi 1,61 ? b0:???shl $0x4,%edx 1,02 ? ? mov -0x14(%ebp),%edi 2,04 ? ? add -0x10(%ebp),%edx 2,24 ? ? lea 0x1(%ebx),%ebx 0,27 ? ? movzbl (%edi,%edx,1),%edx 9,92 ? ? mov %esi,%edi 0,39 ? ? test %dl,%dl 2,04 ? ? cmovns %ecx,%edi 4,63 ? ? test $0x40,%dl 0,55 ? ? mov %di,(%eax) 3,76 ? ? mov %esi,%edi 0,71 ? ? cmove %ecx,%edi 3,41 ? ? test $0x20,%dl 0,75 ? ? mov %di,0x2(%eax) 2,43 ? ? mov %esi,%edi 0,59 ? ? cmove %ecx,%edi 4,59 ? ? test $0x10,%dl 0,67 ? ? mov %di,0x4(%eax) 2,55 ? ? mov %esi,%edi 0,78 ? ? cmove %ecx,%edi 4,31 ? ? test $0x8,%dl 0,67 ? ? mov %di,0x6(%eax) 5,76 ? ? mov %esi,%edi 1,80 ? ? cmove %ecx,%edi 4,20 ? ? test $0x4,%dl 0,86 ? ? mov %di,0x8(%eax) 2,98 ? ? mov %esi,%edi 1,37 ? ? cmove %ecx,%edi 4,67 ? ? test $0x2,%dl 0,20 ? ? mov %di,0xa(%eax) 2,78 ? ? mov %esi,%edi 0,75 ? ? cmove %ecx,%edi 3,92 ? ? and $0x1,%edx 0,75 ? ? mov %esi,%edx 2,59 ? ? mov %di,0xc(%eax) 0,59 ? ? cmove %ecx,%edx 3,10 ? ? mov %dx,0xe(%eax) 2,39 ? ? add $0x10,%eax 0,51 ? ? movzbl (%ebx),%edx 2,86 ? ? test %dl,%dl 2,31 ? ???jne b0 0,04 ?128: addl $0x1,-0x10(%ebp) 4,00 ? mov -0x1c(%ebp),%eax 0,04 ? add %eax,-0x18(%ebp) 0,08 ? cmpl $0x10,-0x10(%ebp) ? ? jne a0 which almost goes away from the profile: # cmdline : /home/kirr/local/perf/bin/perf record -g -a sleep 20 # Samples: 49K of event 'cycles' # Event count (approx.): 16799780016 # # Overhead Command Shared Object Symbol # ........ ............... .................... # 27.51% rawv libc-2.13.so [.] __memcpy_ssse3 23.77% vivi-* [kernel.kallsyms] [k] memcpy 9.96% Xorg [unknown] [.] 0xa76f5e12 4.94% vivi-* [vivi] [k] gen_text.constprop.6 4.44% rawv [vivi] [k] gen_twopix 3.17% vivi-* [vivi] [k] vivi_fillbuff 2.45% rawv [vivi] [k] precalculate_line 1.20% swapper [kernel.kallsyms] [k] read_hpet i.e. gen_twopix() overhead dropped from 49% to 4% and gen_text() loops from ~8% to ~4%, and overal cycles count dropped from 31551930117 to 16799780016 which is ~1.9x whole workload speedup. (*) for RGB24 rendering I've introduced x24, which could be thought as synthetic u24 for simplifying the code. That's done because for memcpy used for conditional assignment, gcc generates suboptimal code with more indirections. Fortunately, in C struct assignment is builtin and that's all we need from pixeltype for font rendering.

Now, the labels are named after the cleanup action they'll perform (first), based on how the winbond-cir driver does it. This makes the code a bit more clear and makes changes in the ordering of labels easier to review. This change is applied only to the rc drivers that do significant cleanup in their probe functions: ati-remote, ene-ir, fintek-cir, gpio-ir-recv, ite-cir, nuvoton-cir.

It seems this crash is very reproducible (just bombard the receiver with IR signals during module load), probably because when request_irq is called, any pending intterupt is handled immediately, before request_irq returns and rdev can be set. This same crash was supposed to be fixed by commit 9ef449c6b31bb6a8e6dedc24de475a3b8c79be20 ("[media] rc: Postpone ISR registration"), but the crash was still observed on the nuvoton-cir driver. This commit was tested on nuvoton-cir only.

This crash has not been observed in practice, but there should be a very small window where it could occur.

Change the driver in order to handle all of them. Unfortunately, em2860/em2863 provide only 16 bits for the IR scancode, even when NEC parity is disabled. So, this change should affect only em2874 and newer devices, with provides up to 32 bits for the scancode. Tested with one NEC-16, one NEC-24 and one RC5 IR.

The new logic preserves backwards compatibility and reflects the endpoint configurations we have seen so far: Ep 0x82, isoc => analog Ep 0x82, bulk => analog Ep 0x83, isoc* => audio Ep 0x84, isoc => digital Ep 0x84, bulk => analog or digital** (*: audio should always be isoc) (**: analog, if ep 0x82 is isoc, otherwise digital) [mchehab@redhat.com: Fix a CodingStyle issue: don't break strings into separate lines] Signed-off-by: Frank Schäfer Signed-off-by: Mauro Carvalho Chehab --- drivers/media/usb/em28xx/em28xx-cards.c | 95 ++++++++++++++++++++++++++------- drivers/media/usb/em28xx/em28xx-core.c | 32 ++++++++--- drivers/media/usb/em28xx/em28xx-dvb.c | 34 ++++++++---- drivers/media/usb/em28xx/em28xx-reg.h | 4 +- drivers/media/usb/em28xx/em28xx-video.c | 10 ++-- drivers/media/usb/em28xx/em28xx.h | 12 +++++ 6 files changed, 147 insertions(+), 40 deletions(-) (limited to 'drivers/media') diff --git a/drivers/media/usb/em28xx/em28xx-cards.c b/drivers/media/usb/em28xx/em28xx-cards.c index 873b52f71ab..a6f00181c24 100644 --- a/drivers/media/usb/em28xx/em28xx-cards.c +++ b/drivers/media/usb/em28xx/em28xx-cards.c @@ -6,6 +6,7 @@ Markus Rechberger Mauro Carvalho Chehab Sascha Sommer + Copyright (C) 2012 Frank Schäfer This program is free software; you can redistribute it and/or modify it under the terms of the GNU General Public License as published by @@ -3209,26 +3210,67 @@ static int em28xx_usb_probe(struct usb_interface *interface, if (udev->speed == USB_SPEED_HIGH) size = size * hb_mult(sizedescr); - if (usb_endpoint_xfer_isoc(e) && - usb_endpoint_dir_in(e)) { + if (usb_endpoint_dir_in(e)) { switch (e->bEndpointAddress) { - case EM28XX_EP_AUDIO: - has_audio = true; - break; - case EM28XX_EP_ANALOG: + case 0x82: has_video = true; - dev->alt_max_pkt_size_isoc[i] = size; + if (usb_endpoint_xfer_isoc(e)) { + dev->analog_ep_isoc = + e->bEndpointAddress; + dev->alt_max_pkt_size_isoc[i] = size; + } else if (usb_endpoint_xfer_bulk(e)) { + dev->analog_ep_bulk = + e->bEndpointAddress; + } + break; + case 0x83: + if (usb_endpoint_xfer_isoc(e)) { + has_audio = true; + } else { + printk(KERN_INFO DRIVER_NAME + ": error: skipping audio endpoint 0x83, because it uses bulk transfers !\n"); + } break; - case EM28XX_EP_DIGITAL: - has_dvb = true; - if (size > dev->dvb_max_pkt_size_isoc) { - dev->dvb_max_pkt_size_isoc = - size; - dev->dvb_alt_isoc = i; + case 0x84: + if (has_video && + (usb_endpoint_xfer_bulk(e))) { + dev->analog_ep_bulk = + e->bEndpointAddress; + } else { + has_dvb = true; + if (usb_endpoint_xfer_isoc(e)) { + dev->dvb_ep_isoc = e->bEndpointAddress; + if (size > dev->dvb_max_pkt_size_isoc) { + dev->dvb_max_pkt_size_isoc = size; + dev->dvb_alt_isoc = i; + } + } else { + dev->dvb_ep_bulk = e->bEndpointAddress; + } } break; } } + /* NOTE: + * Old logic with support for isoc transfers only was: + * 0x82 isoc => analog + * 0x83 isoc => audio + * 0x84 isoc => digital + * + * New logic with support for bulk transfers + * 0x82 isoc => analog + * 0x82 bulk => analog + * 0x83 isoc* => audio + * 0x84 isoc => digital + * 0x84 bulk => analog or digital** + * (*: audio should always be isoc) + * (**: analog, if ep 0x82 is isoc, otherwise digital) + * + * The new logic preserves backwards compatibility and + * reflects the endpoint configurations we have seen + * so far.

With the preceding fixes and improvements, it works fine with both, vbi and non-vbi data streams without performance impacts. So rename em28xx_urb_data_copy_vbi() to em28xx_urb_data_copy(), delete the the old implementation of em28xx_urb_data_copy() and change the code to use this function for both data stream types. Tested with "SilverCrest 1.3 MPix webcam" (progressive, non-vbi) and "Hauppauge HVR-900 (65008/A1C0)" (interlaced, vbi enabled and disabled).

charset=UTF-8 Content-Transfer-Encoding: 8bit When a new frame header is detected in em28xx_urb_data_copy() and the data packet contains both, VBI data and video data, the prevoius VBI buffer doesn't get finished and is overwritten with the new VBI data. This bug is not triggered with isochronous USB transfers, because the data packetes are much smaller than the VBI data size. But when using USB bulk transfers, the whole data of an URB is treated as single packet, which is usually much larger then the VBI data size. Refactor the VBI data processing code to fix this bug, but also to simplify the code and make it similar to the video data processing code part (which allows further code abstraction/unification in the future). The changes have been tested with device "Hauppauge HVR-900".

The alternative would be to call videobuf_to_vmalloc() for each processed USB data packet (isoc USB transfers => 64 times per URB) in the em28xx_copy_*() functions. With the next commits, the data processing code will be split into functions for serveral reasons: - em28xx_urb_data_copy() is generally way to long, making it less readable - there is code duplication between VBI and video data processing - support for em25xx data processing (uses a different header and frame end signaling mechanism) will be added This would require extensive usage of pointer-pointers, which usually makes the code less readable and prone to bugs. The better solution is to cache the pointer in struct em28xx_buffer. This also improves consistency, because we already track the buffer fill count there.

So, prefer it, if the device is a webcam. Tested with Silvercrest 1.3 Mpixel webcam (em2710) on both bulk and isoc modes. Tested analog with HVR-950 model 65201/A1C0 (em2883), where only ISOC endpoints are available for both DVB and Analog. Tested on Hauppauge WinTV USB 2 (em2840) on both bulk and isoc modes. It should be noticed that enabling bulk mode by default with TV boards is a bad idea; what happens is that, while with ISOC the USB logic will prevent the concurrent usage of two devices that spends more than 100% of the USB2 traffic, it doesn't care with bulk transfers. On my tests, I started two streams, one with a WinTV at 640x480x30fps and the other one with a Silvercrest webcam at 640x480, on a lower fps) both on bulk mode. One of the streams always silently failed.

Only its framerate was hardcoded to NTSC's 30fps, while in my country we usually use PAL (25 fps) and I needed that to precisely simulate bandwidth. That's why here is this patch with ->enum_frameintervals() and ->{g,s}_parm() implemented as suggested by Hans Verkuil which passes v4l2-compliance and manual testing through v4l2-ctl -P / -p . Regarding newly introduced __get_format(u32 pixelformat) I decided not to convert original get_format() to operate on fourcc codes, since >= 3 places in driver need to deal with v4l2_format and otherwise it won't be handy.

Unfortunately, frontend ioctls can be blocked by the frontend thread for several seconds; this leads to unacceptable lock contention. Mitigate that by pushing the mutex from dvb_usercopy down to the individual, device specific ioctls. There are 10 such ioctl functions using dvb_usercopy, either calling it directly, or via the trivial wrapper dvb_generic_ioctl. The following already employ their own locking and look safe: • dvb_demux_ioctl (as per dvb_demux_do_ioctl) • dvb_dvr_ioctl (as per dvb_dvr_do_ioctl) • dvb_osd_ioctl (as per single non-trivial callee) • fdtv_ca_ioctl (as per callees) • dvb_frontend_ioctl The following functions do not, and are thus changed to use a device specific mutex: • dvb_net_ioctl (as per dvb_net_do_ioctl) • dvb_ca_en50221_io_ioctl (as per dvb_ca_en50221_io_do_ioctl) • dvb_video_ioctl • dvb_audio_ioctl • dvb_ca_ioctl Signed-off-by: Nikolaus Schulz Signed-off-by: Michael Krufky Signed-off-by: Mauro Carvalho Chehab --- drivers/media/dvb-core/dvb_ca_en50221.c | 9 +++++ drivers/media/dvb-core/dvb_net.c | 71 ++++++++++++++++++++++----------- drivers/media/dvb-core/dvb_net.h | 1 + drivers/media/dvb-core/dvbdev.c | 2 - drivers/media/pci/ttpci/av7110.c | 2 + drivers/media/pci/ttpci/av7110.h | 2 + drivers/media/pci/ttpci/av7110_av.c | 8 ++++ drivers/media/pci/ttpci/av7110_ca.c | 24 +++++++---- 8 files changed, 87 insertions(+), 32 deletions(-) (limited to 'drivers/media') diff --git a/drivers/media/dvb-core/dvb_ca_en50221.c b/drivers/media/dvb-core/dvb_ca_en50221.c index 9be65a3b931..190e5e0f48c 100644 --- a/drivers/media/dvb-core/dvb_ca_en50221.c +++ b/drivers/media/dvb-core/dvb_ca_en50221.c @@ -156,6 +156,9 @@ struct dvb_ca_private { /* Slot to start looking for data to read from in the next user-space read operation */ int next_read_slot;

Rather than try to fix the driver to cope (as has been done by Andy Walls for the cx18 driver), put in a pm_qos_request to limit deep sleep exit latencies. The visible effect of not having this is that seemingly random lines are only partly transferred - if you feed in a static image, you see a portion of the image "flicker" into place.

When the device has an I2C remote, all it needs to do is to call the proper I2C driver (ir-i2c-kbd), passing the proper data to it, and just leave the code. Also, button devices have its own init code that doesn't depend on having an IR or not (as a general rule, they don't have). So, move its init code to fix bugs introduced by earlier patches that prevent them to work.

charset=UTF-8 Content-Transfer-Encoding: 8bit The main purpose of this patch is to move the call of em28xx_release_resources() after the call of em28xx_close_extension(). This is necessary, because some resources might be needed/used by the extensions fini() functions when they get closed. Also mark the device as disconnected earlier in this function and unify the em28xx_uninit_usb_xfer() calls for analog and digital mode.

All other chip variants support reading of max. 64 bytes at once (according to the em258x datasheet; also verified with em2710, em2882, and em28174). Since em2800_i2c_recv_bytes() has been fixed to return with -EOPNOTSUPP when more than 4 bytes are requested, EEPROM reading with this chip is broken. It was actually broken before that change, too, it just didn't throw an error because the i2c adapter silently returned trash data (for all reads >1 byte !).

OTOH, holding .video_lock in soc_camera_open() isn't enough to protect the host during its building of the pipeline, because .video_lock is per soc-camera device. If, e.g. more than one sensor can be attached to a host and the user tries to open both device nodes simultaneously, host's .add() method can be called simultaneously for both sensors. Fix these problems by holding list_lock instead of .host_lock in scan_add_host() and taking it shortly at the beginning of soc_camera_open(), and using .host_lock to protect host's .add() and .remove() operations only.

MEDIA_IOC_SETUP_LINK ioctl mutex_lock(video_lock) mutex_lock(graph_lock) fimc_pipeline_open() fimc_md_link_notify() mutex_lock(graph_lock) mutex_lock(video_lock) ... ... The deadlock is avoided by always taking the graph mutex first in video node open() or an ioctl, before the video lock is acquired. Reversed order seems impossible, since media device driver's link_notify callback is called with media graph mutex already held. To ensure proper locking order VIDIOC_S_FMT and VIDIOC_TRY_FMT ioctls are not serialized in the v4l2-core and the driver takes care of it itself.

This is helpful in situations when range of a control depends on user configurable parameters, e.g. camera sensor absolute exposure time depending on an output image resolution and frame rate. v4l2_ctrl_modify_range() function allows to modify range of an INTEGER, BOOL, MENU, INTEGER_MENU and BITMASK type controls.

The spec specifies that for radio devices only mono and stereo audmodes are valid. If the user specifies another audmode in v4l2_tuner, then that should be mapped to valid audmode. That didn't happen here. Note that tuner drivers might decide to limit the possible audmode even further if it only supports mono. In that case the tuner driver can set audmode to mono. However, that new value wasn't copied back to t->audmode, and that has been fixed as well in this patch.

In case of a configuration where video is captured at the video node exposed by the FIMC-LITE driver there is a following video pipeline: sensor -> MIPI-CSIS.n -> FIMC-LITE.n subdev -> FIMC-LITE.n video node In this situation s_stream() handler of the FIMC-LITE.n is called back from within VIDIOC_STREAMON/OFF ioctl of the FIMC-LITE.n video node, through vb2_stream_on/off(), start/stop_streaming and fimc_pipeline_call(set_stream). The fimc->lock mutex is already held then, before invoking vidioc_streamon/off. So it must not be taken again in the s_stream() callback in this case, to avoid a deadlock. This patch makes fimc->out_path atomic_t so the mutex don't need to be taken in the FIMC-LITE subdev s_stream() callback in the DMA output case.

Such sensors can be connected through FIMC-LITEn (and MIPI-CSISn) IPs to the ISP, which then feeds image data to the FIMCn IP. Thus there can be two busses associated with an image source (sensor). Rename struct s5p_fimc_isp_info describing external image sensor (video decoder) to struct fimc_source_info to avoid confusion. bus_type is split into fimc_bus_type and sensor_bus_type. The bus type enumeration is extended to include both FIMC Writeback input types. The bus_type enumeration and the data structure name in the board files are modified according to the above changes.

This also fixed a nasty issue where opening the radio would set dev->input to 5 for no good reason. This was never set back to a valid TV input after closing the radio device, thus leaving it at 5 which is out of bounds of the vinput card array.

Finally the driver does not implement custom file operation but it uses the generic ones from videobuf2 and v4l2_fh Signed-off-by: Federico Vaga Acked-by: Giancarlo Asnaghi Acked-by: Hans Verkuil Signed-off-by: Mauro Carvalho Chehab --- drivers/media/pci/sta2x11/Kconfig | 2 +- drivers/media/pci/sta2x11/sta2x11_vip.c | 1073 +++++++++++++------------------ 2 files changed, 434 insertions(+), 641 deletions(-) (limited to 'drivers/media') diff --git a/drivers/media/pci/sta2x11/Kconfig b/drivers/media/pci/sta2x11/Kconfig index 6749f67cab8..a94ccad0206 100644 --- a/drivers/media/pci/sta2x11/Kconfig +++ b/drivers/media/pci/sta2x11/Kconfig @@ -2,7 +2,7 @@ config STA2X11_VIP tristate "STA2X11 VIP Video For Linux" depends on STA2X11 select VIDEO_ADV7180 if MEDIA_SUBDRV_AUTOSELECT - select VIDEOBUF_DMA_CONTIG + select VIDEOBUF2_DMA_CONTIG depends on PCI && VIDEO_V4L2 && VIRT_TO_BUS help Say Y for support for STA2X11 VIP (Video Input Port) capture diff --git a/drivers/media/pci/sta2x11/sta2x11_vip.c b/drivers/media/pci/sta2x11/sta2x11_vip.c index 1352e50e457..4b703fe8c95 100644 --- a/drivers/media/pci/sta2x11/sta2x11_vip.c +++ b/drivers/media/pci/sta2x11/sta2x11_vip.c @@ -1,7 +1,11 @@ /* * This is the driver for the STA2x11 Video Input Port. * + * Copyright (C) 2012 ST Microelectronics + * author: Federico Vaga * Copyright (C) 2010 WindRiver Systems, Inc. + * authors: Andreas Kies + * Vlad Lungu * * This program is free software;

It isn't an i2c module at all, instead it should be in common since it is used by 4 pci drivers.

It is now called at analog streaming start only. This has unveiled a bug that causes USB bulk transfers to fail with all urbs having status -EVOERFLOW. The reason is, that for bulk transfers usb_set_interface() needs to be called even if the previous alt setting was the same (side note: bulk transfers seem to work only with alt=0). While it seems to be NOT necessary for isoc transfers, it's reasonable to just call usb_set_interface() unconditionally in em28xx_set_alternate(). Also add a comment that explains the issue to prevent regressions in the future.

However, some of these devices (like mine) come with a different USB PID 0x3009 instead of 0x3006. There have already been patches simply overwriting the USB PID in dvb-usb-ids.h. Of course these patches were rejected because they would have disabled the 0x3006 PID. This new patch adds the 0x3009 PID to dvb-usb-ids.h, and adds references to it within the ttusb2.c driver. PID 0x3006 devices will continue to work. The only difference between the two hardware models seems to be the EEPROM chip. In fact, Windows BDA driver names the 0x3009 device with a "(8 kB EEPROM)" suffix. In spite of that, the 0x3009 device works absolutely flawlessly using the existing ttusb2 driver.
