2024-02-01media: platform: mtk-mdp3: add support second sets of MMSYSMoudy Ho
The MT8195 chipset features two MMSYS subsets: VPPSYS0 and VPPSYS1. These subsets coordinate and control the clock, power, and register settings required for the components of MDP3.

2024-02-01media: rkisp1: Fix IRQ handling due to shared interruptsTomi Valkeinen
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.

2024-02-01media: Revert "media: rkisp1: Drop IRQF_SHARED"Tomi Valkeinen
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.

The main changes are: 1) Add BPF token support to delegate a subset of BPF subsystem functionality from privileged system-wide daemons such as systemd through special mount options for userns-bound BPF fs to a trusted & unprivileged application. With addressed changes from Christian and Linus' reviews, from Andrii Nakryiko. 2) Support registration of struct_ops types from modules which helps projects like fuse-bpf that seeks to implement a new struct_ops type, from Kui-Feng Lee. 3) Add support for retrieval of cookies for perf/kprobe multi links, from Jiri Olsa. 4) Bigger batch of prep-work for the BPF verifier to eventually support preserving boundaries and tracking scalars on narrowing fills, from Maxim Mikityanskiy. 5) Extend the tc BPF flavor to support arbitrary TCP SYN cookies to help with the scenario of SYN floods, from Kuniyuki Iwashima. 6) Add code generation to inline the bpf_kptr_xchg() helper which improves performance when stashing/popping the allocated BPF objects, from Hou Tao. 7) Extend BPF verifier to track aligned ST stores as imprecise spilled registers, from Yonghong Song. 8) Several fixes to BPF selftests around inline asm constraints and unsupported VLA code generation, from Jose E. Marchesi. 9) Various updates to the BPF IETF instruction set draft document such as the introduction of conformance groups for instructions, from Dave Thaler. 10) Fix BPF verifier to make infinite loop detection in is_state_visited() exact to catch some too lax spill/fill corner cases, from Eduard Zingerman. 11) Refactor the BPF verifier pointer ALU check to allow ALU explicitly instead of implicitly for various register types, from Hao Sun. 12) Fix the flaky tc_redirect_dtime BPF selftest due to slowness in neighbor advertisement at setup time, from Martin KaFai Lau. 13) Change BPF selftests to skip callback tests for the case when the JIT is disabled, from Tiezhu Yang. 14) Add a small extension to libbpf which allows to auto create a map-in-map's inner map, from Andrey Grafin. * tag 'for-netdev' of https://git.kernel.org/pub/scm/linux/kernel/git/bpf/bpf-next: (107 commits) selftests/bpf: Add missing line break in test_verifier bpf, docs: Clarify definitions of various instructions bpf: Fix error checks against bpf_get_btf_vmlinux(). bpf: One more maintainer for libbpf and BPF selftests selftests/bpf: Incorporate LSM policy to token-based tests selftests/bpf: Add tests for LIBBPF_BPF_TOKEN_PATH envvar libbpf: Support BPF token path setting through LIBBPF_BPF_TOKEN_PATH envvar selftests/bpf: Add tests for BPF object load with implicit token selftests/bpf: Add BPF object loading tests with explicit token passing libbpf: Wire up BPF token support at BPF object level libbpf: Wire up token_fd into feature probing logic libbpf: Move feature detection code into its own file libbpf: Further decouple feature checking logic from bpf_object libbpf: Split feature detectors definitions from cached results selftests/bpf: Utilize string values for delegate_xxx mount options bpf: Support symbolic BPF FS delegation mount options bpf: Fail BPF_TOKEN_CREATE if no delegation option was set on BPF FS bpf,selinux: Allocate bpf_security_struct per BPF token selftests/bpf: Add BPF token-enabled tests libbpf: Add BPF token support to bpf_prog_load() API ... ==================== Link: https://lore.kernel.org/r/20240126215710.19855-1-daniel@iogearbox.net Signed-off-by: Jakub Kicinski <kuba@kernel.org>

2024-01-24media: vb2: refactor setting flags and caps, fix missing capHans Verkuil
Several functions implementing VIDIOC_REQBUFS and _CREATE_BUFS all use almost the same code to fill in the flags and capability fields. Refactor this into a new vb2_set_flags_and_caps() function that replaces the old fill_buf_caps() and validate_memory_flags() functions. This also fixes a bug where vb2_ioctl_create_bufs() would not set the V4L2_BUF_CAP_SUPPORTS_MAX_NUM_BUFFERS cap and also not fill in the max_num_buffers field.
