The ivsc drivers may use the ipu-bridge but currently it's possible to link the ivsc to the kernel and ipu-bridge as a module. This won't work. Require that the ipu-bridge is either linked to the kernel or disabled if ivsc is linked to the kernel as well, by depending on IPU_BRIDGE or !IPU_BRIDGE.

It was reported to me that the imx219 didn't work on one of our development kits partly because the access sequence is incorrect. The datasheet I could find [1] for this camera has the access sequence: Seq. No. Address (Hex) data 1 30EB 05 2 30EB 0C 3 300A FF 4 300B FF 5 30EB 05 6 30EB 09 but the driver swaps the first two elements. Laurent pointed out on IRC that the original code used the correct sequence for 1920x1080 but the current sequence for 3280x2464 and 1640x1232. During refactoring of the init sequence the current order was used for all formats. Switch to using the documented sequence.

2024-06-15media: ipu-bridge: Add HIDs from out of tree IPU6 driver ipu-bridge copyHans de Goede1-3/+19
The out of tree IPU6 driver comes with its own copy of the ipu-bridge code. It also comes bundled with standard v4l2 sensor drivers. Many of these have been mainlined and the rest is being mainlined but not all are upstream yet. The latest version of the out of tree code now will use the mainline kernel ipu-bridge version when build against new enough kernels. This however breaks support for (bundled) sensor drivers which do not (yet) have an entry in the mainline ipu-bridge code. Add the missing entries to the mainline ipu-bridge code to make the transition to having everything in mainline easier. The alternative HID for the OV13B10 and the OV08x40 entries both are for sensors already supported in mainline which were missing. The downside of adding these HIDs is that this will cause the IPU3 / IPU6 drivers to delay registering there /dev/video# nodes until a sensor driver has bound, which for the non mainline drivers may never happen. This is not really an issue because almost all IPU designs only have front (user) facing sensors and all the added HIDs are for the main RGB (not IR) sensor. So if the sensor driver is missing then the user can already not use the camera and adding these HIDs does not really change that.

2024-06-15efi/x86: Free EFI memory map only when installing a new one.Ard Biesheuvel1-9/+0
The logic in __efi_memmap_init() is shared between two different execution flows: - mapping the EFI memory map early or late into the kernel VA space, so that its entries can be accessed; - the x86 specific cloning of the EFI memory map in order to insert new entries that are created as a result of making a memory reservation via a call to efi_mem_reserve(). In the former case, the underlying memory containing the kernel's view of the EFI memory map (which may be heavily modified by the kernel itself on x86) is not modified at all, and the only thing that changes is the virtual mapping of this memory, which is different between early and late boot. In the latter case, an entirely new allocation is created that carries a new, updated version of the kernel's view of the EFI memory map. When installing this new version, the old version will no longer be referenced, and if the memory was allocated by the kernel, it will leak unless it gets freed. The logic that implements this freeing currently lives on the code path that is shared between these two use cases, but it should only apply to the latter. So move it to the correct spot. While at it, drop the dummy definition for non-x86 architectures, as that is no longer needed.

2024-06-14mlxsw: Use the same maximum MTU value throughout the driverAmit Cohen3-26/+6
Currently, the driver uses two different values for maximum MTU, one is stored in mlxsw_port->dev->max_mtu and the second is stored in mlxsw_port->max_mtu. The second one is set to value which is queried from firmware. This value was never tested, and unfortunately is not really supported. That means that with the existing code, user can set MTU to X, which is not really supported by firmware and which is bigger than buffer size which is allocated in pci. To make the driver consistent, use only mlxsw_port->dev->max_mtu for maximum MTU value, for buffers headroom add Ethernet frame headers, which are not included in mlxsw_port->dev->max_mtu.

2024-06-14mlxsw: Adjust MTU value to hardware checkAmit Cohen2-1/+2
Ethernet frame consists of - Ethernet header, payload, FCS. The MTU value which is used by user is the size of the payload, which means that when user sets MTU to X, the total frame size will be larger due to the addition of the Ethernet header and FCS. Spectrum ASICs take into account Ethernet header and FCS as part of packet size for MTU check. Adjust MTU value when user sets MTU, to configure the MTU size which is required by hardware.

Move the code returning the XPCS into dwmac-intel, which is the only user of XPCS. Fill in the select_pcs() implementation only when we are going to setup the XPCS, thus when it should be present.
