[e500v2 / e500mc] R^X memory pages support?

[davychoplin]

Hello,

R^X memory pages support is not common on ARM and x86 architectures, I am wondering if it is the same for QorIQ processors.

When reading the e500v2 and e500mc reference manuals, I have the feeling that it is possible to add TLB with execute only rights (without read / write rights).

Is my understanding correct?

Best regards,

Davy C.

Your understanding is correct.

For more details please refer to the EREF: A Programmer’s Reference Manual for Freescale Power Architecture Processors, 7.5.8 Permission Attributes.
