2019-06-11media: vicodec: improve handling of ENC_CMD_STOP/STARTHans Verkuil
Correctly handle stopping and restarting the encoder, keeping track of the stop and drain states. In addition it adds correct handling of corner cases, allowing v4l2-compliance to pass. Unfortunately, the code is getting to be quite complicated, so we need to work on better codec support in v4l2-mem2mem.c to simplify drivers.

2019-06-11media: vicodec: use correct sizeimage value when drainingHans Verkuil
After a resolution change is detected, q_data->sizeimage is updated to the new format, but buf_prepare is still draining buffers that need to use the old pre-resolution-change value. So store the sizeimage value in q_data->vb2_sizeimage in queue_setup and use that in buf_prepare.

2019-06-11media: vicodec: add V4L2_CID_MIN_BUFFERS_FOR_OUTPUTHans Verkuil

2019-06-11media: vicodec: pass on enc output format to capture sideHans Verkuil
Setting the encoder output format to e.g. 1920x1080 will set the crop rectangle to 1920x1088, the coded resolution to 1920x1088 and the capture coded resolution and sizeimage to 1920x1088 as well. Note that this might change, since the encoder spec is still in flux with respect to how this should behave.

2019-06-10media: ttpci: use rc-core for the IR receiverSean Young
The IR protocol can now only be set via the rc protocols sysfs file rather than via module parameters or a custom procfs file. So, it is no longer necessary to periodically check for protocol changes. The IR_RCMM protocol does not decode the Philips RC-MM protocol (12, 24 or 32 bit variants) or any protocol rc-core can encode, so this is marked RC_PROTO_UNKNOWN. Tested on Technotrend/Hauppauge WinTV Nexus-S rev2.1, which comes with a small black hauppauge remote.

2019-06-08i2c: xiic: Add max_read_len quirkRobert Hancock
This driver does not support reading more than 255 bytes at once because the register for storing the number of bytes to read is only 8 bits. Add a max_read_len quirk to enforce this. This was found when using this driver with the SFP driver, which was previously reading all 256 bytes in the SFP EEPROM in one transaction. This caused a bunch of hard-to-debug errors in the xiic driver since the driver/logic was treating the number of bytes to read as zero. Rejecting transactions that aren't supported at least allows the problem to be diagnosed more easily.

I've pushed an update to linux-firmware with the new FW version, which unfortunately contains API changes vs the older firmware.

some boards Some newer boards with these chipsets aren't compatible with the prior version of the SEC2 FW, and fail to load as a result. This newer FW is actually the one we already use on >=GP108. Unfortunately, there are interface differences in GP108's FW, making it impossible to simply move files around in linux-firmware to solve this. We need to be able to keep compatibility with all linux-firmware/kernel combinations, which means supporting both firmwares. Signed-off-by: Ben Skeggs <bskeggs@redhat.com>

git://git.kernel.org/pub/scm/linux/kernel/git/deller/parisc-linux Pull parisc fixes from Helge Deller: - Fix crashes when accessing PCI devices on some machines like C240 and J5000. The crashes were triggered because we replaced cache flushes by nops in the alternative coding where we shouldn't for some machines. - Dave fixed a race in the usage of the sr1 space register when used to load the coherence index. - Use the hardware lpa instruction to to load the physical address of kernel virtual addresses in the iommu driver code. - The kernel may fail to link when CONFIG_MLONGCALLS isn't set. Solve that by rearranging functions in the final vmlinux executeable. - Some defconfig cleanups and removal of compiler warnings. * 'parisc-5.2-3' of git://git.kernel.org/pub/scm/linux/kernel/git/deller/parisc-linux: parisc: Fix crash due alternative coding for NP iopdir_fdc bit parisc: Use lpa instruction to load physical addresses in driver code parisc: configs: Remove useless UEVENT_HELPER_PATH parisc: Use implicit space register selection for loading the coherence index of I/O pdirs parisc: Fix compiler warnings in float emulation code parisc/slab: cleanup after /proc/slab_allocators removal parisc: Allow building 64-bit kernel without -mlong-calls compiler option parisc: Kconfig: remove ARCH_DISCARD_MEMBLOCK

The root cause for that is that during re-connection all the queues are destroyed and re-created (and the ib_device is reference counted by the queues and freed as well) but the tagset stays alive and all the DMA mappings (that we perform in init_request) kept in the request context. The original commit fixed a different bug that was introduced during bonding (aka nic teaming) tests that for some scenarios change the underlying ib_device and caused memory leakage and possible segmentation fault. This commit is a complementary commit that also changes the wrong DMA mappings that were saved in the request context and making the request sqe dma mappings dynamic with the command lifetime (i.e. mapped in .queue_rq and unmapped in .complete). It also fixes the above crash of accessing freed ib_device during destruction of the tagset.

2019-06-06parisc: Use lpa instruction to load physical addresses in driver codeJohn David Anglin
Most I/O in the kernel is done using the kernel offset mapping. However, there is one API that uses aliased kernel address ranges: > The final category of APIs is for I/O to deliberately aliased address > ranges inside the kernel. Such aliases are set up by use of the > vmap/vmalloc API. Since kernel I/O goes via physical pages, the I/O > subsystem assumes that the user mapping and kernel offset mapping are > the only aliases. This isn't true for vmap aliases, so anything in > the kernel trying to do I/O to vmap areas must manually manage > coherency. It must do this by flushing the vmap range before doing > I/O and invalidating it after the I/O returns. For this reason, we should use the hardware lpa instruction to load the physical address of kernel virtual addresses in the driver code. I believe we only use the vmap/vmalloc API with old PA 1.x processors which don't have a sba, so we don't hit this problem. Tested on c3750, c8000 and rp3440.

index of I/O pdirs We only support I/O to kernel space. Using %sr1 to load the coherence index may be racy unless interrupts are disabled. This patch changes the code used to load the coherence index to use implicit space register selection. This saves one instruction and eliminates the race. Tested on rp3440, c8000 and c3750.
