CAPTURE_COMPLETE and FRAME_COMPLETE interrupts come even when these are disabled in the VE_INTERRUPT_CTRL register and eventually this behavior causes disabling irq itself like below: [10055.108784] irq 23: nobody cared (try booting with the "irqpoll" option) [10055.115525] CPU: 0 PID: 331 Comm: swampd Tainted: G W 5.3.0-4fde000-dirty-d683e2e #1 [10055.124565] Hardware name: Generic DT based system [10055.129355] Backtrace: [10055.131854] [<80107d7c>] (dump_backtrace) from [<80107fb0>] (show_stack+0x20/0x24) [10055.139431] r7:00000017 r6:00000001 r5:00000000 r4:9d51dc00 [10055.145120] [<80107f90>] (show_stack) from [<8074bf50>] (dump_stack+0x20/0x28) [10055.152361] [<8074bf30>] (dump_stack) from [<80150ffc>] (__report_bad_irq+0x40/0xc0) [10055.160109] [<80150fbc>] (__report_bad_irq) from [<80150f2c>] (note_interrupt+0x23c/0x294) [10055.168374] r9:015b6e60 r8:00000000 r7:00000017 r6:00000001 r5:00000000 r4:9d51dc00 [10055.176136] [<80150cf0>] (note_interrupt) from [<8014df1c>] (handle_irq_event_percpu+0x88/0x98) [10055.184835] r10:7eff7910 r9:015b6e60 r8:00000000 r7:9d417600 r6:00000001 r5:00000002 [10055.192657] r4:9d51dc00 r3:00000000 [10055.196248] [<8014de94>] (handle_irq_event_percpu) from [<8014df64>] (handle_irq_event+0x38/0x4c) [10055.205113] r5:80b56d50 r4:9d51dc00 [10055.208697] [<8014df2c>] (handle_irq_event) from [<80151f1c>] (handle_level_irq+0xbc/0x12c) [10055.217037] r5:80b56d50 r4:9d51dc00 [10055.220623] [<80151e60>] (handle_level_irq) from [<8014d4b8>] (generic_handle_irq+0x30/0x44) [10055.229052] r5:80b56d50 r4:00000017 [10055.232648] [<8014d488>] (generic_handle_irq) from [<8014d524>] (__handle_domain_irq+0x58/0xb4) [10055.241356] [<8014d4cc>] (__handle_domain_irq) from [<801021e4>] (avic_handle_irq+0x68/0x70) [10055.249797] r9:015b6e60 r8:00c5387d r7:00c5387d r6:ffffffff r5:9dd33fb0 r4:9d402380 [10055.257539] [<8010217c>] (avic_handle_irq) from [<80101e34>] (__irq_usr+0x54/0x80) [10055.265105] Exception stack(0x9dd33fb0 to 0x9dd33ff8) [10055.270152] 3fa0: 015d0530 00000000 00000000 015d0538 [10055.278328] 3fc0: 015d0530 015b6e60 00000000 00000000 0052c5d0 015b6e60 7eff7910 7eff7918 [10055.286496] 3fe0: 76ce5614 7eff7908 0050e2f4 76a3a08c 20000010 ffffffff [10055.293104] r5:20000010 r4:76a3a08c [10055.296673] handlers: [10055.298967] [<79f218a5>] irq_default_primary_handler threaded [<1de88514>] aspeed_video_irq [10055.307344] Disabling IRQ #23 To fix this issue, this commit makes the interrupt handler clear these garbage interrupts. This driver enables and uses only COMP_COMPLETE interrupt instead for frame handling.
