[meta-ti] [RFC 1/2] linux/cmem.inc: Support reserving memory for CMEM.
To reserve contiguous memory for CMEM:
* include the recipes-kernel/linux/cmem.inc
* Set CMEM_BASE and CMEM_SIZE to the physical memory address and size,
respectively, to reserve for CMEM.
Currently limited to reserving a single memory region used to create
a single buffer pool of a single buffer.

[meta-ti] [RFC 2/2] linux-ti-staging_3.14: Add CMEM region for omap-a15.
* This region can be used by applications to enable shared contiguous
memory in user space for data transfer between the ARM and DSP.

[meta-ti] [RFC 0/2] Proposal for enabling CMEM
This is a proposal for adding a CMEM region in the device tree. I wanted to get comments on the following: * implementation of using an inc file to enable this. * Whether the actual configuration belongs in the kernel recipe, or if this is something that should be handled at the distro or branding level. (RFC sets the configuration in kernel recipe). - I have verified that this configuration may also be set in the branding file using, for example, CMEM_BASE_pn-linux-ti-staging_omap-a15 = a000 CMEM_SIZE_pn-linux-ti-staging_omap-a15 = 2000 Jacob Stiffler (2): linux/cmem.inc: Support reserving memory for CMEM. linux-ti-staging_3.14: Add CMEM region for omap-a15. recipes-kernel/linux/cmem.inc | 22 ++ recipes-kernel/linux/linux-ti-staging_3.14.bb |6 +- recipes-kernel/linux/linux/cmem.dtsi | 24 3 files changed, 51 insertions(+), 1 deletion(-) create mode 100644 recipes-kernel/linux/cmem.inc create mode 100644 recipes-kernel/linux/linux/cmem.dtsi -- 1.7.9.5 -- ___ meta-ti mailing list meta-ti@yoctoproject.org https://lists.yoctoproject.org/listinfo/meta-ti
