CONFIG_PERCEPIO_RECORDER_TRC_CFG_PAGED_EVENT_BUFFER_PAGE_SIZE

Paged Event Buffer Page Size

Type: int

Help

Specifies the size of each page in the paged event buffer. This can be tuned
to match any internal low-level buffers used by the streaming interface, like
the Ethernet MTU (Maximum Transmission Unit). However, since the currently
active page can't be transfered, having more but smaller pages is more
efficient with respect memory usage, than having a few large pages.
