This serie add support for elf64 in remoteproc (elf loader, coredump). First three patches modifies the type of len argument (in da_to_va), boot_addr and rproc_mem_entry len field in order to allow loading elf64 segment with a u64 size and a u64 entry point. Next patches introduce a set of macros to access elf64 and elf32 transparently. Last patches are the actual modifications in the elf loader and remoteproc coredump support to add elf64 support. Changes v4 -> v5: - Add rproc_elf_sanity_check renaming to rproc_elf32_sanity_check - Fix checkpatch warning on > 80 column line - Change u64 len type for size_t in da_to_va and add checks in loader - Modify rproc_mem_entry size field type from int to size_t - Add a patch to override sanity_check function Changes v3 -> v4: - Adapt coredump to elf64 file format - Rename remoteproc_elf_loader.h to remoteproc_elf_helpers.h - Update copyright year in remoteproc_elf_helpers.h - Rename macros elf_hdr_* to elf_get_hdr_* for coherency with elf_hdr_set_* - Split elf64 loader patch in 3: - boot_addr u64 change - remoteproc_elf_helpers.h creation - elf64 loading Changes v2 -> v3: - da_to_va len type changed from int to u64 - Add check for elf64 header size - Add comments for name table parsing - Fix typo in "accommodate - Add ELF64 support in documentation Clement Leger (8): remoteproc: Use size_t type for len in da_to_va remoteproc: Use size_t instead of int for rproc_mem_entry len remoteproc: Use u64 type for boot_addr remoteproc: Add elf helpers to access elf64 and elf32 fields remoteproc: Rename rproc_elf_sanity_check for elf32 remoteproc: Add elf64 support in elf loader remoteproc: Allow overriding only sanity_check remoteproc: Adapt coredump to generate correct elf type Documentation/remoteproc.txt | 2 +- drivers/remoteproc/imx_rproc.c | 11 +- drivers/remoteproc/keystone_remoteproc.c | 4 +- drivers/remoteproc/qcom_q6v5_adsp.c | 2 +- drivers/remoteproc/qcom_q6v5_mss.c | 2 +- drivers/remoteproc/qcom_q6v5_pas.c | 2 +- drivers/remoteproc/qcom_q6v5_wcss.c | 2 +- drivers/remoteproc/qcom_wcnss.c | 2 +- drivers/remoteproc/remoteproc_core.c | 86 +++++++------ drivers/remoteproc/remoteproc_debugfs.c | 2 +- drivers/remoteproc/remoteproc_elf_helpers.h | 96 ++++++++++++++ drivers/remoteproc/remoteproc_elf_loader.c | 189 +++++++++++++++++++--------- drivers/remoteproc/remoteproc_internal.h | 14 ++- drivers/remoteproc/st_remoteproc.c | 4 +- drivers/remoteproc/st_slim_rproc.c | 6 +- drivers/remoteproc/stm32_rproc.c | 2 +- drivers/remoteproc/wkup_m3_rproc.c | 4 +- include/linux/remoteproc.h | 13 +- 18 files changed, 317 insertions(+), 126 deletions(-) create mode 100644 drivers/remoteproc/remoteproc_elf_helpers.h -- 2.15.0.276.g89ea799
