How to set inner of outer shareability on page table entry WITHOUT TEX remap??

At first, sorry to my fool English.

I want to know how to set to inner or outer shareable attribute on page table entry using TEX, C, B and  S bit (without TEX remap).

I knew if i use TEX remap, the PRRR NOT bit used to set to outer or inner but i didn't find explain in without TEX remap.

Thanks.

  • Hi levi,

    The quick answer is that you can just set the TEX encoding to reflect the shareability and use the "S" bit for certain encodings, you just can't set inner/outer shareability separately - but certain TEX values do infer shareability for both regions. This is documented in B3.8.2 of the ARMv7-AR ARM ("Short-descriptor format memory region attributes, without TEX remap."
