2024-06-19dma-buf/heaps: Correct the types of fd_flags and heap_flagsBarry Song1-2/+2
dma_heap_allocation_data defines the UAPI as follows: struct dma_heap_allocation_data { __u64 len; __u32 fd; __u32 fd_flags; __u64 heap_flags; }; But dma heaps are casting both fd_flags and heap_flags into unsigned long. This patch makes dma heaps - cma heap and system heap have consistent types with UAPI.

2024-06-12drm/bridge-connector: implement glue code for HDMI connectorDmitry Baryshkov1-0/+81
In order to let bridge chains implement HDMI connector infrastructure, add necessary glue code to the drm_bridge_connector. In case there is a bridge that sets DRM_BRIDGE_OP_HDMI, drm_bridge_connector will register itself as a HDMI connector and provide proxy drm_connector_hdmi_funcs implementation. Note, to simplify implementation, there can be only one bridge in a chain that sets DRM_BRIDGE_OP_HDMI. Setting more than one is considered an error. This limitation can be lifted later, if the need arises.

This is to be used by the drivers if setup of the infoframes is not tightly coupled with the audio functionality and just disabling the audio playback doesn't stop the HDMI hardware from sending the Infoframe.

2024-06-07drm/mipi-dbi: Add support for DRM_FORMAT_RGB888Noralf Trønnes1-0/+5
DRM_FORMAT_RGB888 is 24 bits per pixel and it would be natural to send it on the SPI bus using a 24 bits per word transfer. The problem with this is that not all SPI controllers support 24 bpw. Since DRM_FORMAT_RGB888 is stored in memory as little endian and the SPI bus is big endian we use 8 bpw to always get the same pixel format on the bus: b8g8r8. The MIPI DCS specification lists the standard commands that can be sent over the MIPI DBI interface. The set_address_mode (36h) command has one bit in the parameter that controls RGB/BGR order. This means that the controller can be configured to receive the pixel as BGR. RGB888 is rarely supported on these controllers but RGB666 is very common. All datasheets I have seen do at least support the pixel format option where each color is sent as one byte and the 6 MSB's are used. All this put together means that we can send each pixel as b8g8r8 and an RGB666 capable controller sees this as b6x2g6x2r6x2. v4: - s/emulation_format/pixel_format/ (Dmitry) Reviewed-by: Dmitry Baryshkov <dmitry.baryshkov@linaro.org> Link: https://patchwork.freedesktop.org/patch/msgid/20240604-panel-mipi-dbi-rgb666-v4-4-d7c2bcb9b78d@tronnes.org Signed-off-by: Noralf Trønnes <noralf@tronnes.org>
2024-06-07drm/mipi-dbi: Make bits per word configurable for pixel transfersNoralf Trønnes1-0/+5
MIPI DCS write/set commands have 8 bit parameters except for the write_memory commands where it depends on the pixel format. drm_mipi_dbi does currently only support RGB565 which is 16-bit and it has to make sure that the pixels enters the SPI bus in big endian format since the MIPI DBI spec doesn't have support for little endian. drm_mipi_dbi is optimized for DBI interface option 3 which means that the 16-bit bytes are swapped by the upper layer if the SPI bus does not support 16 bits per word, signified by the swap_bytes member. In order to support both 16-bit and 24-bit pixel transfers we need a way to tell the DBI command layer the format of the buffer. Add a write_memory_bpw member that the upper layer can use to tell how many bits per word to use for the SPI transfer. v4: - Expand the commit message (Dmitry) Reviewed-by: Dmitry Baryshkov <dmitry.baryshkov@linaro.org> Link: https://patchwork.freedesktop.org/patch/msgid/20240604-panel-mipi-dbi-rgb666-v4-3-d7c2bcb9b78d@tronnes.org Signed-off-by: Noralf Trønnes <noralf@tronnes.org>

2024-06-05rtnetlink: make the "split" NLM_DONE handling genericJakub Kicinski1-0/+1
Jaroslav reports Dell's OMSA Systems Management Data Engine expects NLM_DONE in a separate recvmsg(), both for rtnl_dump_ifinfo() and inet_dump_ifaddr(). We already added a similar fix previously in commit 460b0d33cf10 ("inet: bring NLM_DONE out to a separate recv() again") Instead of modifying all the dump handlers, and making them look different than modern for_each_netdev_dump()-based dump handlers - put the workaround in rtnetlink code. This will also help us move the custom rtnl-locking from af_netlink in the future (in net-next). Note that this change is not touching rtnl_dump_all(). rtnl_dump_all() is different kettle of fish and a potential problem. We now mix families in a single recvmsg(), but NLM_DONE is not coalesced. Tested: ./cli.py --dbg-small-recv 4096 --spec netlink/specs/rt_addr.yaml \ --dump getaddr --json '{"ifa-family": 2}' ./cli.py --dbg-small-recv 4096 --spec netlink/specs/rt_route.yaml \ --dump getroute --json '{"rtm-family": 2}' ./cli.py --dbg-small-recv 4096 --spec netlink/specs/rt_link.yaml \ --dump getlink Fixes: 3e41af90767d ("rtnetlink: use xarray iterator to implement rtnl_dump_ifinfo()") Fixes: cdb2f80f1c10 ("inet: use xa_array iterator to implement inet_dump_ifaddr()") Reported-by: Jaroslav Pulchart <jaroslav.pulchart@gooddata.com> Link: https://lore.kernel.org/all/CAK8fFZ7MKoFSEzMBDAOjoUt+vTZRRQgLDNXEOfdCCXSoXXKE0g@mail.gmail.com Signed-off-by: Jakub Kicinski <kuba@kernel.org> Reviewed-by: Eric Dumazet <edumazet@google.com> Signed-off-by: David S.

2024-06-04PCI: Revert the cfg_access_lock lockdep mechanismDan Williams2-7/+0
While the experiment did reveal that there are additional places that are missing the lock during secondary bus reset, one of the places that needs to take cfg_access_lock (pci_bus_lock()) is not prepared for lockdep annotation. Specifically, pci_bus_lock() takes pci_dev_lock() recursively and is currently dependent on the fact that the device_lock() is marked lockdep_set_novalidate_class(&dev->mutex). Otherwise, without that annotation, pci_bus_lock() would need to use something like a new pci_dev_lock_nested() helper, a scheme to track a PCI device's depth in the topology, and a hope that the depth of a PCI tree never exceeds the max value for a lockdep subclass. The alternative to ripping out the lockdep coverage would be to deploy a dynamic lock key for every PCI device. Unfortunately, there is evidence that increasing the number of keys that lockdep needs to track to be per-PCI-device is prohibitively expensive for something like the cfg_access_lock. The main motivation for adding the annotation in the first place was to catch unlocked secondary bus resets, not necessarily catch lock ordering problems between cfg_access_lock and other locks. Solve that narrower problem with follow-on patches, and just due to targeted revert for now.

2024-06-04iommu: Return right value in iommu_sva_bind_device()Lu Baolu1-1/+1
iommu_sva_bind_device() should return either a sva bond handle or an ERR_PTR value in error cases. Existing drivers (idxd and uacce) only check the return value with IS_ERR(). This could potentially lead to a kernel NULL pointer dereference issue if the function returns NULL instead of an error pointer. In reality, this doesn't cause any problems because iommu_sva_bind_device() only returns NULL when the kernel is not configured with CONFIG_IOMMU_SVA. In this case, iommu_dev_enable_feature(dev, IOMMU_DEV_FEAT_SVA) will return an error, and the device drivers won't call iommu_sva_bind_device() at all.

git://git.kernel.org/pub/scm/linux/kernel/git/andi.shyti/linux into i2c/for-current Removed the SPD class of i2c devices from the device core. Additionally, a cleanup in the Synquacer code removes the pclk from the global structure, as it is used only in the probe. Therefore, it is now declared locally.
2024-06-02net/tcp: Don't consider TCP_CLOSE in TCP_AO_ESTABLISHEDDmitry Safonov1-3/+4
TCP_CLOSE may or may not have current/rnext keys and should not be considered "established". The fast-path for TCP_CLOSE is SKB_DROP_REASON_TCP_CLOSE. This is what tcp_rcv_state_process() does anyways. Add an early drop path to not spend any time verifying segment signatures for sockets in TCP_CLOSE state.

git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/tty Pull tty fix from Greg KH: "Here is a single revert for a much-reported regression in 6.10-rc1 when it comes to a few older architectures. Turns out that the VT ioctls don't work the same across all cpu types because of some old compatibility requrements for stuff like alpha and powerpc. So revert the change that attempted to have them use the _IO() macros and go back to the known-working values instead. This has NOT been in linux-next but has had many reports that it fixes the issue with 6.10-rc1" * tag 'tty-6.10-rc2' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/tty: Revert "VT: Use macros to define ioctls"
2024-06-01Revert "VT: Use macros to define ioctls"Greg Kroah-Hartman1-49/+47
This reverts commit 8c467f3300591a206fa8dcc6988d768910799872. Turns out this breaks many architectures as the vt ioctls do not all match up everywhere due to historical reasons, so the original commit is invalid for many values.
