xtensa: remove unnecessary padding in arch_mem_domain #71896

Open ldmstm opened 6 months ago

Is your enhancement proposal related to a problem? Please describe. The current definition of arch_mem_domain for the xtensa architecture (https://github.com/zephyrproject-rtos/zephyr/blob/023248a1f33cfd29655de2c4a9bfd13f2af3424b/include/zephyr/arch/xtensa/arch.h#L65) forcefully aligns one of its members to a page boundary, adding unnecessary padding.

I suspect the intention behind this alignment is to indicate the pointer points to an MMU page-size aligned address, but instead it aligns the pointer storage itself.

Describe the solution you'd like The __aligned directive needs to be removed.
