Interface/API changes:
SharedRegion_DEFAULTOWNERID has been removed from the SharedRegon common header file, ti/ipc/SharedRegion.h (SDOCM00083271). Applications referencing this value should use MultiProc_INVALIDID instead (defined in ti/ipc/MultiProc.h).
Most of the APIs in IPC 1.24 are compatible with IPC 1.22/1.23. However, code using IPC 1.22/1.23 will have to be recompiled for use with IPC 1.24.00. You must recompile -- relink will not work.
ti.sdo.ipc.* and ti.sdo.utils.* APIs in the IPC 1.2X.XX.XX releases are not compatible with those in the IPC 1.00.0X.XX (GA) release. These APIs have been updated to be consistent with the Linux APIs to share common header files in ti/ipc/. However, APIs in the ti.sdo.io package have not changed since the 1.00 GA release.
OMAP3530 Mailbox assignments swapped
In previous IPC releases, Mailbox 0 was used for DSP-to-ARM notifications and 1 was used for ARM-to-DSP communication. This has been swapped as of IPC 1.22.02. In order for ARM-DSP notifications to work, both the ARM and the DSP must use the same mailbox assignments.
DM8168 MultiProc name changesThis release supports the following operating systems:
This release requires the following other software components and tools versions to successfully function:
No known issues
All releases have 4 digits (M.mm.pp.bb). This includes GA and pre-releases (engineering, EA, beta, etc.). Pre-releases are denoted with a suffix (e.g. 1.21.00.01_eng).
This product's version follows a version format, M.mm.pp.bb, where M is a single digit Major number, mm is 2 digit minor number, pp is a 2 digit patch number, and b is an unrestricted set of digits used as an incrementing build counter.
To support multiple side-by-side installations of the product, the product version is encoded in the top level directory, ex. ipc_1_21_00_01.
Subsequent releases of patch upgrades will be identified by the patch number, ex. IPC 1.21.00.01 with directory ipc_1_21_00_01. Typically, these patches only include critical bug fixes.
Please note that version numbers and compatibility keys are NOT the same. For an explanation of compatibility keys, please refer to the 'Upgrade and Compatibility Information' section.
