Dma-buf isn't needed here since it's only an interaction between the kernel and secure world. This patchset fixes this by intruducing three new function tee_shm_alloc_user_buf(), tee_shm_alloc_kernel_buf() and tee_shm_alloc_anon_kernel_buf() to be used instead of the old tee_shm_alloc(). This should make the API a bit easier to use both within the TEE subsystem and for the tee clients in various drivers. The patch set starts with simplifying the shared memory pool handling, an internal matter for the two TEE drivers OP-TEE and AMDTEE. Thanks, Jens Jens Wiklander (7): tee: remove unused tee_shm_pool_alloc_res_mem() tee: simplify shm pool handling tee: add tee_shm_alloc_kernel_buf() hwrng: optee-rng: use tee_shm_alloc_kernel_buf() tpm_ftpm_tee: use tee_shm_alloc_kernel_buf() firmware: tee_bnxt: use tee_shm_alloc_kernel_buf() tee: replace tee_shm_alloc() drivers/char/hw_random/optee-rng.c | 6 +- drivers/char/tpm/tpm_ftpm_tee.c | 8 +- drivers/firmware/broadcom/tee_bnxt_fw.c | 5 +- drivers/tee/amdtee/shm_pool.c | 55 ++----- drivers/tee/optee/Kconfig | 8 - drivers/tee/optee/call.c | 16 +- drivers/tee/optee/core.c | 76 +-------- drivers/tee/optee/device.c | 5 +- drivers/tee/optee/rpc.c | 8 +- drivers/tee/optee/shm_pool.c | 51 +++--- drivers/tee/optee/shm_pool.h | 2 +- drivers/tee/tee_core.c | 2 +- drivers/tee/tee_private.h | 11 -- drivers/tee/tee_shm.c | 209 ++++++++++++++++++------ drivers/tee/tee_shm_pool.c | 160 ++++-------------- include/linux/tee_drv.h | 106 +++--------- 16 files changed, 291 insertions(+), 437 deletions(-) -- 2.31.1
