This series contains a few general cleanups in the Qualcomm SMEM code, reorganizing some things so memory partitions are treated more consistently, and to avoid some duplication. A few patches change existing behavior, as highlighted below. Each of these changes has been tested and verified to function with available hardware. -Alex Alex Elder (12): soc: qcom: smem: rename variable in qcom_smem_get_global() soc: qcom: smem: initialize region struct only when successful These two are simple cleanups. soc: qcom: smem: always ignore partitions with 0 offset or size This patch makes partitions with a zero offset always be ignored. Previously this condition was flagged as an error in one place and ignored in another. soc: qcom: smem: small refactor in qcom_smem_enumerate_partitions() This just simplifies a little logic in one spot. soc: qcom: smem: verify both host ids in partition header This patch makes it so *both* IDs, not just one or the other, must use the special value SMEM_GLOBAL_HOST to signify the special global partition. soc: qcom: smem: require order of host ids to match A memory partition is described by an entry in a partition table, which identifies two hosts permitted to access the partition. A partition also embeds a header, which also identifies the hosts. Previously the host ids could be in any order; now the two host ids are required to be listed in the same order in the partition table and header. soc: qcom: smem: introduce qcom_smem_partition_header() soc: qcom: smem: verify partition header size soc: qcom: smem: verify partition offset_free_uncached soc: qcom: smem: small change in global entry loop soc: qcom: smem: verify partition host ids match These patches together introduce a single function to locate a partition header in memory, and to validate its contents. The common function is used in two place and removes some duplication. The patches build up the function in steps to facilitate review. soc: qcom: smem: a few last cleanups This patch gathers a small set of trivial cleanups. drivers/soc/qcom/smem.c | 173 +++++++++++++++++++++++------------------------- 1 file changed, 82 insertions(+), 91 deletions(-) -- 2.14.1 -- To unsubscribe from this list: send the line "unsubscribe linux-arm-msm" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
