* [media] cx23885: use sg = sg_next(sg) instead of sg++Hans Verkuil2014-11-211-3/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The cx23885 driver still used sg++ instead of sg = sg_next(sg). This worked with vb1 since that filled in the sglist manually, page-by-page, but it fails with vb2 which uses core scatterlist code that can combine contiguous scatterlist entries into one larger entry. This bug led to the following crash as reported by Mariusz: [20712.990258] BUG: Bad page state in process vb2-cx23885[0] pfn:2ca34 [20712.990265] page:ffffea00009c3b60 count:-1 mapcount:0 mapping: (null) index:0x0 [20712.990266] flags: 0x4000000000000000() [20712.990268] page dumped because: nonzero _count [20712.990269] Modules linked in: tun binfmt_misc nf_conntrack_ipv6 nf_defrag_ipv6 ip6table_filter ip6_tables xt_mark xt_REDIRECT xt_limit xt_conntrack xt_nat xt_tcpudp iptable_mangle iptable_nat nf_conntrack_ipv4 nf_defrag_ipv4 nf_nat_ipv4 nf_nat nf_conntrack iptable_filter ip_tables x_tables sit ip_tunnel nvidia(PO) stb6100 stv090x cx88_dvb videobuf_dvb cx88_vp3054_i2c tuner kvm_amd kvm cx8802 k10temp cx8800 cx88xx btcx_risc videobuf_dma_sg videobuf_core usb_storage ds2490 usbhid ftdi_sio cx23885 tveeprom cx2341x videobuf2_dvb videobuf2_core videobuf2_dma_sg videobuf2_memops asus_atk0110 snd_emu10k1 snd_hwdep snd_util_mem snd_ac97_codec ac97_bus snd_rawmidi snd_pcm_oss snd_mixer_oss snd_pcm snd_timer snd w1_therm wire ipv6 [20712.990301] CPU: 2 PID: 26942 Comm: vb2-cx23885[0] Tainted: P B W O 3.18.0-rc5-00001-gb3652d1 #2 [20712.990303] Hardware name: System manufacturer System Product Name/M4A785TD-V EVO, BIOS 2105 07/23/2010 [20712.990305] ffffffff81765734 ffff880137683a78 ffffffff815b6b32 0000000000000006 [20712.990307] ffffea00009c3b60 ffff880137683aa8 ffffffff8108ec27 ffffffff81765712 [20712.990309] ffffffff8189c840 0000000000000246 ffffea00009c3b60 ffff880137683b78 [20712.990312] Call Trace: [20712.990317] [<ffffffff815b6b32>] dump_stack+0x46/0x58 [20712.990321] [<ffffffff8108ec27>] bad_page+0xe9/0x107 [20712.990323] [<ffffffff810912ca>] get_page_from_freelist+0x3b2/0x505 [20712.990326] [<ffffffff8109150a>] __alloc_pages_nodemask+0xed/0x65f [20712.990330] [<ffffffff81047a52>] ? ttwu_do_activate.constprop.78+0x57/0x5c [20712.990332] [<ffffffff81049ff3>] ? try_to_wake_up+0x21b/0x22d [20712.990336] [<ffffffff810070f4>] dma_generic_alloc_coherent+0x6e/0xf5 [20712.990339] [<ffffffff810261a9>] gart_alloc_coherent+0x105/0x114 [20712.990341] [<ffffffff81025963>] ? flush_gart+0x39/0x3d [20712.990343] [<ffffffff810260a4>] ? gart_map_sg+0x3a0/0x3a0 [20712.990349] [<ffffffffa0141a1e>] cx23885_risc_databuffer+0xa7/0x133 [cx23885] [20712.990354] [<ffffffffa0142764>] cx23885_buf_prepare+0x121/0x134 [cx23885] [20712.990359] [<ffffffffa0144210>] buffer_prepare+0x14/0x16 [cx23885] [20712.990363] [<ffffffffa011f101>] __buf_prepare+0x190/0x279 [videobuf2_core] [20712.990366] [<ffffffffa011d906>] ? vb2_queue_or_prepare_buf+0xb8/0xc0 [videobuf2_core] [20712.990369] [<ffffffffa011f34b>] vb2_internal_qbuf+0x51/0x1e5 [videobuf2_core] [20712.990372] [<ffffffffa0120537>] vb2_thread+0x199/0x1f6 [videobuf2_core] [20712.990376] [<ffffffffa012039e>] ? vb2_fop_write+0xdf/0xdf [videobuf2_core] [20712.990379] [<ffffffff81043e61>] kthread+0xdf/0xe7 [20712.990381] [<ffffffff81043d82>] ? kthread_create_on_node+0x16d/0x16d [20712.990384] [<ffffffff815bd46c>] ret_from_fork+0x7c/0xb0 [20712.990386] [<ffffffff81043d82>] ? kthread_create_on_node+0x16d/0x16d Signed-off-by: Hans Verkuil <hans.verkuil@cisco.com> Reported-by: Mariusz Bialonczyk <manio@skyboo.net> Tested-by: Mariusz Bialonczyk <manio@skyboo.net> Signed-off-by: Mauro Carvalho Chehab <mchehab@osg.samsung.com>

* [media] cx23885: remove btcx-risc dependencyHans Verkuil2014-09-081-17/+19
| | | | | | | | | | It's just as easy to do it in the driver. This dependency only uses a fraction of the btcx-risc module and doing it directly in the driver adds only a few lines. The btcx-risc module is really meant for the bttv driver, not for other drivers. Signed-off-by: Hans Verkuil <hans.verkuil@cisco.com> Signed-off-by: Mauro Carvalho Chehab <m.chehab@samsung.com>
* [media] cx23885: convert to vb2Hans Verkuil2014-09-081-220/+85
| | | | | | | | | | | | | | | | | | | | | | | | As usual, this patch is very large due to the fact that half a vb2 conversion isn't possible. And since this affects 417, alsa, core, dvb, vbi and video the changes are all over. What made this more difficult was the peculiar way the risc program was setup. The driver allowed for running out of buffers in which case the DMA would stop and restart when the next buffer was queued. There was also a complicated timeout system for when buffers weren't filled. This was replaced by a much simpler scheme where there is always one buffer around and the DMA will just cycle that buffer until a new buffer is queued. In that case the previous buffer will be chained to the new buffer. An interrupt is generated at the start of the new buffer telling the driver that the previous buffer can be passed on to userspace. Much simpler and more robust. The old code seems to be copied from the cx88 driver. But it didn't fit the vb2 ops very well and replacing it with the new scheme made the code easier to understand. Not to mention that this patch removes 600 lines of code. Signed-off-by: Hans Verkuil <hans.verkuil@cisco.com> Signed-off-by: Mauro Carvalho Chehab <m.chehab@samsung.com>

| * Drivers: media: remove __dev* attributes.Greg Kroah-Hartman2013-01-031-4/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | CONFIG_HOTPLUG is going away as an option. As a result, the __dev* markings need to be removed. This change removes the use of __devinit, __devexit_p, __devinitdata, __devinitconst, and __devexit from these drivers. Based on patches originally written by Bill Pemberton, but redone by me in order to handle some of the coding style issues better, by hand.
