The SK Hynix Hi-846 is a 1/4" 8M Pixel CMOS Image Sensor. It supports usual features like I2C control, CSI-2 for frame data, digital/analog gain control or test patterns. This driver supports the 640x480, 1280x720 and 1632x1224 resolution modes. It supports runtime PM in order not to draw any unnecessary power. The part is also called YACG4D0C9SHC and a datasheet can be found at https://product.skhynix.com/products/cis/cis.go The large sets of partly undocumented register values are for example found when searching for the hi846_mipi_raw_Sensor.c Android driver.

In existing video driver implementation vpp frequency calculation in calculate_inst_freq() is always zero because the value of vpp_freq_per_mb is always zero for decoder. Fixed this by correcting the calculating the vpp frequency calculation for decoder. Fixes: 3cfe5815 ("media: venus: Enable low power setting for encoder") Signed-off-by:

Video driver maintains an internal context for the output buffer size. During S_fmt() on capture plane, the output buffer size is not updated in driver context. As a result, during buf_prepare(), the size of the vb2_plane and internal size of the buffer, as maintained by the driver, does not match. This leads to buf_prepare() failure. Update the instance context for the output buffer size during s_fmt(). Signed-off-by:

In current video driver implementation in calculate_inst_freq() frequency is calculated based on filled_len. The filled_len may vary frame to frame, because of this in load_scale_v4() since frequency is calculated for all instances, driver is throwing false warning like "HW is overloaded". Hence to handle this, changed log level to low log message. Since the actual session rejection is happening in decide_core() based on load. Signed-off-by:

Remove soft reset between frames, which was merely a workaround, actually replace it with something less aggressive: clearing of jpeg stream buffer pointer, via STM_CTRL[BITBUF_PTR_CLR]. According to the reference manual, the BITBUF_PTR_CLR is performed on context switch, but, per hardware team recommendation, it is also working without context switch, which is the case for this driver, for now. Without soft reset and without BITBUF_PTR_CLR, successive encoding jobs continue from where the previous left off, basically writing past the v4l2 buffer. Signed-off-by:

The AXI ID is an AXI bus configuration for improve bus performance. If read and write operations use different IDs the operations can be paralleled, whereas when they have the same ID the operations will be serialized. Right now, the write ID is fixed to 0 but we can set it to 0xff to get auto generated IDs to avoid possible conflicts. This change has no functional changes, but seems reasonable to let the hardware to autogenerate the ID instead of hardcoding in software. Signed-off-by:

In commit b212921b ("elf: don't use MAP_FIXED_NOREPLACE for elf executable mappings") we still leave MAP_FIXED_NOREPLACE in place for load_elf_interp. Unfortunately, this will cause kernel to fail to start with: 1 (init): Uhuuh, elf segment at 00003ffff7ffd000 requested but the memory is mapped already Failed to execute /init (error -17) The reason is that the elf interpreter (ld.so) has overlapping segments. readelf -l ld-2.31.so Program Headers: Type Offset VirtAddr PhysAddr FileSiz MemSiz Flags Align LOAD 0x0000000000000000 0x0000000000000000 0x0000000000000000 0x000000000002c94c 0x000000000002c94c R E 0x10000 LOAD 0x000000000002dae0 0x000000000003dae0 0x000000000003dae0 0x00000000000021e8 0x0000000000002320 RW 0x10000 LOAD 0x000000000002fe00 0x000000000003fe00 0x000000000003fe00 0x00000000000011ac 0x0000000000001328 RW 0x10000 The reason for this problem is the same as described in commit ad55eac7 ("elf: enforce MAP_FIXED on overlaying elf segments"). Not only executable binaries, elf interpreters (e.g. ld.so) can have overlapping elf segments, so we better drop MAP_FIXED_NOREPLACE and go back to MAP_FIXED in load_elf_interp.
