* [media] vivid: Y offset should depend on quant. rangeHans Verkuil2015-01-291-4/+6
| | | | | | | | | | When converting to or from Y'CbCr and R'G'B' the Y offset depends on the quantization range: it's 0 for full and 16 for limited range. But in the code it was hardcoded to 16. This messed up the brightness of the generated pattern. Signed-off-by: Hans Verkuil <hans.verkuil@cisco.com> Signed-off-by: Mauro Carvalho Chehab <mchehab@osg.samsung.com>
* [media] smiapp: Don't compile of_read_number() if CONFIG_OF isn't definedSakari Ailus2015-01-291-0/+4
| | | | | | | | | | | of_read_number() is defined in of.h but does not return an error code, so that non-of implementation could simply return an error. Temporarily work around this until of_read_number() can be replaced by of_property_read_u64_array().

* [media] Revert "[media] v4l: omap4iss: Add module debug parameter"Laurent Pinchart2015-01-271-5/+0
| | | | | | | | | | | | | This reverts commit 186612342500b0af8498d7c8bc6b3ac32ac7a48e. The video_device debug field has been renamed to dev_debug, resulting in a compilation failure. As v4l2 debugging is supposed to be controlled through a sysfs attribute created by the v4l2 core, there's no need to duplicate debug control through a module parameter. Remove it.

* [media] uvcvideo: Remove extra commit on resume()Aviv Greenberg2015-01-271-3/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The UVC spec is a bit vague wrt devices using bulk endpoints, specifically, how to signal to a device to start streaming. For devices using isoc endpoints, the sequence for start streaming is: 1) The host sends PROBE_CONTROL(SET_CUR) PROBE_CONTROL(GET_CUR) 2) Host selects desired config and calls COMMIT_CONTROL(SET_CUR) 3) Host selects an alt interface other then zero - e.g SELECT_ALTERNATE_INTERFACE(1) 4) The device starts streaming However for devices using bulk endpoints, there must be *no* alt interface other than setting zero. From the UVC spec: "A VideoStreaming interface containing a bulk endpoint for streaming shall support only alternate setting zero. Additional alternate settings containing bulk endpoints are not permitted in a device that is compliant with the Video Class specification." So for devices using bulk endpoints, step #3 above is irrelevant, and thus cannot be used as an indication for the device to start streaming. So in practice, such devices start streaming immediately after a COMMIT_CONTROL(SET_CUR). In the uvc resume() handler, an unsolicited commit is sent, which causes devices using bulk endpoints to start streaming unintentionally. This patch modifies resume() handler to send a commit only if streaming needs to be reestablished, i.e if the device was actually streaming before is was suspended.

* [media] hdmi: added unpack and logging functions for InfoFramesMartin Bugge2015-01-272-7/+819
| | | | | | | | | | | | | | When receiving video it is very useful to be able to unpack the InfoFrames. Logging is useful as well, both for transmitters and receivers. Especially when implementing the VIDIOC_LOG_STATUS ioctl (supported by many V4L2 drivers) for a receiver it is important to be able to easily log what the InfoFrame contains. This greatly simplifies debugging.

| | | | | | | | | | | | | | | | | | | | | | | Remove tea575x-specific code from bttv and use the common driver instead. Only set_frequency is implemented (signal/stereo detection or seek would require more changes to bttv). It works fine on Video Highway Xtreme (it actually makes the radio usable as it currently cannot be tuned properly). Miro/Pinnacle is untested but seems to be simple and should work. However, I don't understand the Terratec Active Radio Upgrade code. The HW seems to need IOR, IOW and CSEL signals that were taken from ISA bus on older cards (IOR and IOW directly and CSEL from some address decoder) and are emulated here using GPIOs. But the code manipulating these signals in bttv seems to be broken - it never asserts the IOR signal. If anyone has this HW, please test if I got that right.

As explained by Paul Bolle in http://lkml.kernel.org/r/1348488259.1436.22.camel@x61.thuisdomein "Fast TSC calibration failed" should not be considered as an error since other calibration methods are being tried afterward. At most, those send a warning if they fail (not an error). So let's change the message from error to warning. [ tglx: Make if pr_info.

| | * x86/apic: Re-enable PCI_MSI support for non-SMP X86_32Bryan O'Donoghue2015-01-231-1/+5
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Commit 0dbc6078c06bc0 ('x86, build, pci: Fix PCI_MSI build on !SMP') introduced the dependency that X86_UP_APIC is only available when PCI_MSI is false. This effectively prevents PCI_MSI support on 32bit UP systems because it disables both APIC and IO-APIC. But APIC support is architecturally required for PCI_MSI. The intention of the patch was to enforce APIC support when PCI_MSI is enabled, but failed to do so. Remove the !PCI_MSI dependency from X86_UP_APIC and enforce X86_UP_APIC when PCI_MSI support is enabled on 32bit UP systems.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Commit 281d4078bec3 ("x86: Make page cache mode a real type") introduced the symbols __cachemode2pte_tbl and __pte2cachemode_tbl and exported them via EXPORT_SYMBOL_GPL. The exports are part of a replacement of code which has been EXPORT_SYMBOL before these changes resulting in build breakage of out-of-tree non-gpl modules. Change EXPORT_SYMBOL_GPL to EXPORT-SYMBOL for these two symbols.

| | * x86, tls: Interpret an all-zero struct user_desc as "no segment"Andy Lutomirski2015-01-222-2/+36
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The Witcher 2 did something like this to allocate a TLS segment index: struct user_desc u_info; bzero(&u_info, sizeof(u_info)); u_info.entry_number = (uint32_t)-1; syscall(SYS_set_thread_area, &u_info); Strictly speaking, this code was never correct. It should have set read_exec_only and seg_not_present to 1 to indicate that it wanted to find a free slot without putting anything there, or it should have put something sensible in the TLS slot if it wanted to allocate a TLS entry for real. The actual effect of this code was to allocate a bogus segment that could be used to exploit espfix. The set_thread_area hardening patches changed the behavior, causing set_thread_area to return -EINVAL and crashing the game. This changes set_thread_area to interpret this as a request to find a free slot and to leave it empty, which isn't *quite* what the game expects but should be close enough to keep it working. In particular, using the code above to allocate two segments will allocate the same segment both times. According to FrostbittenKing on Github, this fixes The Witcher 2. If this somehow still causes problems, we could instead allocate a limit==0 32-bit data segment, but that seems rather ugly to me.

| | * x86, tls, ldt: Stop checking lm in LDT_emptyAndy Lutomirski2015-01-221-7/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 32-bit programs don't have an lm bit in their ABI, so they can't reliably cause LDT_empty to return true without resorting to memset. They shouldn't need to do this. This should fix a longstanding, if minor, issue in all 64-bit kernels as well as a potential regression in the TLS hardening code.
