[ Upstream commit 114b5b3 ] A64_LDRSW() takes three registers: Xt, Xn, Xm as arguments and it loads and sign extends the value at address Xn + Xm into register Xt. Currently, the offset is being directly used in place of the tmp register which has the offset already loaded by the last emitted instruction. This will cause JIT failures. The easiest way to reproduce this is to test the following code through test_bpf module: { "BPF_LDX_MEMSX | BPF_W", .u.insns_int = { BPF_LD_IMM64(R1, 0x00000000deadbeefULL), BPF_LD_IMM64(R2, 0xffffffffdeadbeefULL), BPF_STX_MEM(BPF_DW, R10, R1, -7), BPF_LDX_MEMSX(BPF_W, R0, R10, -7), BPF_JMP_REG(BPF_JNE, R0, R2, 1), BPF_ALU64_IMM(BPF_MOV, R0, 0), BPF_EXIT_INSN(), }, INTERNAL, { }, { { 0, 0 } }, .stack_depth = 7, }, We need to use the offset as -7 to trigger this code path, there could be other valid ways to trigger this from proper BPF programs as well. This code is rejected by the JIT because -7 is passed to A64_LDRSW() but it expects a valid register (0 - 31). roott@pjy:~# modprobe test_bpf test_name="BPF_LDX_MEMSX | BPF_W" [11300.490371] test_bpf: test_bpf: set 'test_bpf' as the default test_suite.

Preview works fine, but the captures has too much pink.
I have added flash led for the megapixels config but not works yet maybe some udev rules will be needed.
