gpu: ipu-v3: prg: avoid possible array underflow

2018-03-15T16:52:08+00:00

gcc-8 reports that we access an array with a negative index in an error case: drivers/gpu/ipu-v3/ipu-prg.c: In function 'ipu_prg_channel_disable': drivers/gpu/ipu-v3/ipu-prg.c:252:43: error: array subscript -22 is below array bounds of 'struct ipu_prg_channel[3]' [-Werror=array-bounds] This moves the range check in front of the first time that variable gets used.

gpu: ipu-csi: add 10/12-bit grayscale support to mbus_code_to_bus_cfg

2018-02-19T14:13:05+00:00

The 10/12-bit config used for bayer formats is used for grayscale as well. Signed-off-by: Jan Luebbe Signed-off-by: Philipp Zabel

gpu: ipu-cpmem: add 16-bit grayscale support to ipu_cpmem_set_image

2018-02-19T14:13:00+00:00

Add the missing offset calculation for 16-bit grayscale images. Since the IPU only supports capturing greyscale in raw passthrough mode, it is the same as 16-bit bayer formats. Signed-off-by: Philipp Zabel

gpu: ipu-v3: prg: fix device node leak in ipu_prg_lookup_by_phandle

2018-02-19T14:12:59+00:00

Before returning, call of_node_put() for the device node returned by of_parse_phandle(). Fixes: ea9c260514c1 ("gpu: ipu-v3: add driver for Prefetch Resolve Gasket") Signed-off-by: Tobias Jordan Signed-off-by: Philipp Zabel

gpu: ipu-v3: pre: fix device node leak in ipu_pre_lookup_by_phandle

2018-02-19T14:12:59+00:00

Before returning, call of_node_put() for the device node returned by of_parse_phandle(). Fixes: d2a34232580a ("gpu: ipu-v3: add driver for Prefetch Resolve Engine") Signed-off-by: Tobias Jordan Signed-off-by: Philipp Zabel

gpu: ipu-cpmem: add 8-bit grayscale support to ipu_cpmem_set_image

2018-02-16T13:48:11+00:00

Add the missing offset calculation for grayscale images. Since the IPU only supports capturing greyscale in raw passthrough mode, it is the same as 8-bit bayer formats. Signed-off-by: Philipp Zabel

gpu: ipu-v3: make const arrays int_reg static, shrinks object size

2018-02-16T13:47:43+00:00

Don't populate the const read-only arrays int_reg on the stack but instead make them static. Makes the object code smaller by over 80 bytes: Before: text data bss dec hex filename 28024 8936 192 37152 9120 drivers/gpu/ipu-v3/ipu-common.o After: text data bss dec hex filename 27794 9080 192 37066 90ca drivers/gpu/ipu-v3/ipu-common.o (gcc version 7.2.0 x86_64) Signed-off-by: Colin Ian King Signed-off-by: Philipp Zabel

gpu: ipu-v3: allow to build with COMPILE_TEST

2017-12-19T11:49:11+00:00

Add missing include in ipu-cpmem and ipu-ic, select BITREVERSE for ipu-cpmem and GENERIC_ALLOCATOR for ipu-pre, and allow to build if COMPILE_TEST is enabled. Signed-off-by: Philipp Zabel

gpu: ipu-v3: prg: add modifier support

2017-12-19T11:49:11+00:00

Allow to pass through the modifier to the PRE unit and extend the format check with the supported modifiers. Signed-off-by: Lucas Stach Signed-off-by: Philipp Zabel

gpu: ipu-v3: pre: add tiled prefetch support

2017-12-19T11:49:11+00:00

This configures the TPR unit, using the DRM format modifier. For now only the single buffer modifiers are supported, as split buffer needs more configuration for the required cropping.
