media: meson-ge2d: Fix rotation parameter changes detection in 'ge2d_s_ctrl()'

2021-09-30T08:07:39+00:00

There is likely a typo here. To be consistent, we should compare 'fmt.height' with 'ctx->out.pix_fmt.height', not 'ctx->out.pix_fmt.width'. Instead of fixing the test, just remove it and copy 'fmt' unconditionally.

media: meson: Add M2M driver for the Amlogic GE2D Accelerator Unit

2020-12-07T14:05:54+00:00

The GE2D is a 2D accelerator with various features like configurable blitter with alpha blending, frame rotation, scaling, format conversion and colorspace conversion. The driver implements a Memory2Memory VB2 V4L2 streaming device permitting: - 0, 90, 180, 270deg rotation - horizontal/vertical flipping - source cropping - destination compositing - 32bit/24bit/16bit format conversion This adds the support for the GE2D version found in the AXG SoCs Family. The missing features are: - Source scaling - Colorspace conversion - Advanced alpha blending & blitting options Is passes v4l2-compliance: SHA: ea16a7ef13a902793a5c2626b0cefc4d956147f3, 64 bits, 64-bit time_t [hverkuil: add missing linux/bitfield.h include] Signed-off-by: Neil Armstrong Signed-off-by: Hans Verkuil Signed-off-by: Mauro Carvalho Chehab

media: move CEC platform drivers to a separate directory

2020-04-15T10:06:40+00:00

As CEC support doesn't depend on MEDIA_SUPPORT, let's place the platform drivers outside the media menu. As a side effect, instead of depends on PCI, seco driver can select it (and DMI). Acked-by: Hans Verkuil Signed-off-by: Mauro Carvalho Chehab

cec: add cec_adapter to cec_notifier_cec_adap_unregister()

2019-10-07T10:47:43+00:00

It is possible for one HDMI connector to have multiple CEC adapters. The typical real-world scenario is that where one adapter is used when the device is in standby, and one that's better/smarter when the device is powered up. The cec-notifier changes were made with that in mind, but I missed that in order to support this you need to tell cec_notifier_cec_adap_unregister() which adapter you are unregistering from the notifier. Add this additional argument. It is currently unused, but once all drivers use this, the CEC core will be adapted for these use-cases.

media: meson/ao-cec: move cec_notifier_cec_adap_register after hw setup

2019-10-07T09:53:19+00:00

When probed after the HDMI notifier, calling cec_notifier_cec_adap_register() calls the enable() adapter callback, but the HW is not yet set up. Moving cec_notifier_cec_adap_register() right before cec_register_adapter() fixes the following crash: Ignoring spurious kernel translation fault at virtual address 0000000000000008 [...] Hardware name: Khadas VIM (DT) [...] pc : __do_kernel_fault+0xdc/0x120 lr : __do_kernel_fault+0xdc/0x120 [...] Call trace: __do_kernel_fault+0xdc/0x120 do_page_fault+0x180/0x458 do_translation_fault+0x64/0x70 do_mem_abort+0x3c/0x98 el1_da+0x20/0x94 meson_ao_cec_adap_enable+0x30/0x218 [ao_cec] __cec_s_phys_addr+0x184/0x270 cec_s_phys_addr+0x44/0x60 cec_notifier_cec_adap_register+0x68/0x90 meson_ao_cec_probe+0xb0/0x288 [ao_cec] [...] el0_svc_compat+0x8/0x10 Reported-by: Christian Hewitt Suggested-by: Hans Verkuil Fixes: 20958f9d5c48 ("media: meson/ao-cec: use cec_notifier_cec_adap_(un)register") Signed-off-by: Neil Armstrong Signed-off-by: Hans Verkuil Signed-off-by: Mauro Carvalho Chehab
