Detailed Description

Flash Segment Control holds the pointer to the segment, number of pages, various page stats and the memory copy of the page descriptors.

Field Documentation

◆ descriptor

const rtems_fdisk_segment_desc* rtems_fdisk_segment_ctl::descriptor

The descriptor provided by the low-level driver.

◆ device

uint32_t rtems_fdisk_segment_ctl::device

The device this segment resides on.

◆ erased

uint32_t rtems_fdisk_segment_ctl::erased

Counter to debugging. Wear support would remove this.

◆ failed

uint32_t rtems_fdisk_segment_ctl::failed

The segment has failed.

◆ next

struct rtems_fdisk_segment_ctl* rtems_fdisk_segment_ctl::next

Segments with available pages are maintained as a linked list.

◆ page_descriptors

rtems_fdisk_page_desc* rtems_fdisk_segment_ctl::page_descriptors

The in-memory ocpy of the page descriptors found at the start of the segment in the flash device.

◆ pages

uint32_t rtems_fdisk_segment_ctl::pages

Total number of pages in the segment.

◆ pages_active

uint32_t rtems_fdisk_segment_ctl::pages_active

Number of pages flagged as active.

◆ pages_bad

uint32_t rtems_fdisk_segment_ctl::pages_bad

Number of pages detected as bad.

◆ pages_desc

uint32_t rtems_fdisk_segment_ctl::pages_desc

Number of pages used for page descriptors.

◆ pages_used

uint32_t rtems_fdisk_segment_ctl::pages_used

Number of pages flagged as used.

◆ segment

uint32_t rtems_fdisk_segment_ctl::segment

The segment in the device. This must be within the segment descriptor.
