media: rkisp1: Fix IRQ handling due to shared interrupts

2024-02-01T05:47:28+00:00

The driver requests the interrupts as IRQF_SHARED, so the interrupt
handlers can be called at any time. If such a call happens while the ISP
is powered down, the SoC will hang as the driver tries to access the
ISP registers.

This can be reproduced even without the platform sharing the IRQ line:
Enable CONFIG_DEBUG_SHIRQ and unload the driver, and the board will
hang.

Fix this by adding a new field, 'irqs_enabled', which is used to bail
out from the interrupt handler when the ISP is not operational.

media: Revert "media: rkisp1: Drop IRQF_SHARED"

2024-02-01T05:46:46+00:00

This reverts commit 85d2a31fe4d9be1555f621ead7a520d8791e0f74.

The rkisp1 does share interrupt lines on some platforms, after all. Thus
we need to revert this, and implement a fix for the rkisp1 shared irq
handling in a follow-up patch.

Change compatible string to match dt bindings for TI devices. K3 family
prefix should not be included as it deviates from naming convention.

media: videobuf2: core: Rename min_buffers_needed field in vb2_queue

Rename min_buffers_needed into min_queued_buffers and update
the documentation about it.

[hverkuil: Drop the change where min_queued_buffers + 1 buffers would be]
[hverkuil: allocated. Now this patch only renames this field instead of making]
[hverkuil: a functional change as well.]
[hverkuil: Renamed 3 remaining min_buffers_needed occurrences.]

media: s5p-mfc: DPB Count Independent of VIDIOC_REQBUF

2023-12-13T13:33:49+00:00

Add allocation of DPB buffers based on MFC requirement so,
codec buffers allocations has been moved after state
MFCINST_HEAD_PRODUCED. It is taken care that codec buffer allocation
is performed in process context from userspace IOCTL call.

media: s5p-mfc: Set context for valid case before calling try_run

2023-12-13T13:33:49+00:00

Context bit is set for hardware execution if there is a buffer in
source and destination queue before calling try_run in the
init_buffers function. Now there will be a new context created and
hardware will be invoked for the buffer queued instead of waiting for
another buffer to be queued from userspace to set this context bit for
hw execution.
