[media] bdisp: prevent compiling on random arch

2015-06-22T15:56:19+00:00

This driver requires support for DMA attrs function, and not just DMA. Change the options accordingly to remove those errors: /devel/v4l/to_next/drivers/media/platform/sti/bdisp/bdisp-hw.c: In function ‘bdisp_hw_free_nodes’: /devel/v4l/to_next/drivers/media/platform/sti/bdisp/bdisp-hw.c:132:3: error: implicit declaration of function ‘dma_free_attrs’ [-Werror=implicit-function-declaration] dma_free_attrs(ctx->bdisp_dev->dev, ^ /devel/v4l/to_next/drivers/media/platform/sti/bdisp/bdisp-hw.c: In function ‘bdisp_hw_alloc_nodes’: /devel/v4l/to_next/drivers/media/platform/sti/bdisp/bdisp-hw.c:157:9: error: implicit declaration of function ‘dma_alloc_attrs’ [-Werror=implicit-function-declaration] base = dma_alloc_attrs(dev, node_size * MAX_NB_NODE, &paddr, ^ /devel/v4l/to_next/drivers/media/platform/sti/bdisp/bdisp-hw.c:157:7: warning: assignment makes pointer from integer without a cast [-Wint-conversion] base = dma_alloc_attrs(dev, node_size * MAX_NB_NODE, &paddr, ^ /devel/v4l/to_next/drivers/media/platform/sti/bdisp/bdisp-hw.c: In function ‘bdisp_hw_alloc_filters’: /devel/v4l/to_next/drivers/media/platform/sti/bdisp/bdisp-hw.c:219:7: warning: assignment makes pointer from integer without a cast [-Wint-conversion] base = dma_alloc_attrs(dev, size, &paddr, GFP_KERNEL | GFP_DMA, &attrs); Also, get rid of bogus, unused and duplicated symbol declaration for the config option done at bdisp/Kconfig.

[media] bdisp-debug: don't try to divide by s64

2015-06-11T10:34:30+00:00

There are several warnings there, on some architectures, related to dividing a s32 by a s64 value: drivers/media/platform/sti/bdisp/bdisp-debug.c:594: warning: comparison of distinct pointer types lacks a cast drivers/media/platform/sti/bdisp/bdisp-debug.c:594: warning: right shift count >= width of type drivers/media/platform/sti/bdisp/bdisp-debug.c:594: warning: passing argument 1 of '__div64_32' from incompatible pointer type drivers/media/platform/sti/bdisp/bdisp-debug.c:595: warning: comparison of distinct pointer types lacks a cast drivers/media/platform/sti/bdisp/bdisp-debug.c:595: warning: right shift count >= width of type drivers/media/platform/sti/bdisp/bdisp-debug.c:595: warning: passing argument 1 of '__div64_32' from incompatible pointer type CC [M] drivers/media/tuners/mt2060.o drivers/media/platform/sti/bdisp/bdisp-debug.c:596: warning: comparison of distinct pointer types lacks a cast drivers/media/platform/sti/bdisp/bdisp-debug.c:596: warning: right shift count >= width of type drivers/media/platform/sti/bdisp/bdisp-debug.c:596: warning: passing argument 1 of '__div64_32' from incompatible pointer type drivers/media/platform/sti/bdisp/bdisp-debug.c:597: warning: comparison of distinct pointer types lacks a cast drivers/media/platform/sti/bdisp/bdisp-debug.c:597: warning: right shift count >= width of type drivers/media/platform/sti/bdisp/bdisp-debug.c:597: warning: passing argument 1 of '__div64_32' from incompatible pointer type That doesn't make much sense. What the driver is actually trying to do is to divide one second by a value. So, check the range before dividing. That warrants the right result and will remove the warnings on non-64 bits archs. Also fixes this warning: drivers/media/platform/sti/bdisp/bdisp-debug.c:588: warning: comparison of distinct pointer types lacks a cast by using div64_s64() instead of calling do_div() directly.

[media] bdisp: 2D blitter driver using v4l2 mem2mem framework

2015-06-09T21:10:41+00:00

This v4l2 mem2mem driver is a 2D blitter for STMicroelectronics SoC. It uses the v4l2 mem2mem framework. The following features are supported and tested: - Color format conversion (RGB32, RGB24, RGB16, NV12, YUV420P) - Copy - Scale - Flip - Deinterlace - Wide (4K) picture support - Crop Signed-off-by: Fabien Dessenne Signed-off-by: Hans Verkuil [hans.verkuil@cisco.com: added missing slab.h include to bdisp-v4l2.c] Signed-off-by: Mauro Carvalho Chehab
