| hppa-mapped-ring-buffer.patch | mapped-ring-buffer: Round to the shared memory boundary on hppa In map_head_and_body_twice(), the second mmap call fails: mmap2(NULL, 135168, PROT_READ|PROT_WRITE, MAP_SHARED, 3, 0) = 0xf64a2000 mmap2(0xf64b3000, 65536, PROT_READ|PROT_WRITE, MAP_SHARED|MAP_FIXED, 3, 0x1000) = -1 EINVAL (Invalid argument) Due to cache issues, all shared mapping of a page must be equivalently mapped. This requires page mappings to be at the same virtual address modulo 4 MB. Due to a kernel limitation, all mappings to a file must be equivalent. The test can be fixed by rounding the buffer_size used in the mapped ring buffer to 4 MB on hppa. This makes the two mmap mappings equivalent. |
