Subject: [PATCH v2 0/1] mtd: ubi: skip programming unused bits in ubi headers
From: Cheng Ming Lin <chengminglin@...c.com.tw>
v2:
- Modify ubi_io_write_vid_hdr to allow vid_hdr to be written not only at
the start or end of a subpage
- New experiment: perform a vid_hdr shift under subpage support conditions
This patch verification was performed on a Xilinx Zynq-PicoZed board with
mtd-utils version 2.3.0. Tests were conducted using both the nandsim
simulated NAND and a real NAND flash device.
Before modifying ubi/io.c, running the tests in mtd-utils/tests/ubi-tests
exhibited the following issue.
While running the mtd-utils/tests/ubi-tests/runubitests.sh test suite,
the execution reaches rsvol.c where, after ubi_mkvol is called, it
subsequently calls ubi_get_vol_info. At this point, there is a certain
probability of encountering an "error -2, no such file or directory".
To address this, I modified the ubi_mkvol function within mtd-utils by
adding a polling mechanism that waits for the /dev/ubi0_x device node
to be created before proceeding.
However, after adding this polling, the test encountered a similar "no
such file" error in io_paral.c. Further investigation pointed to a
potential issue with mdev. According to mdev documentation, kernel hotplug
events are not serialized and increment the SEQNUM environmental variable
on each invocation. This can cause hotplug and hot-unplug events to be
reordered, which sometimes results in device nodes not being created
as expected.
To solve this, I introduced an mdev.seq to serialize these events,
effectively resolving the problem.
With both modifications—the polling in ubi_mkvol and the mdev.seq
handling — runubitests.sh completes successfully.
Beyond these fixes, to validate the patch’s behavior with and without
subpage support, I also added a new module parameter subpage to nandsim.
This allows dynamically toggling subpage support. Setting the parameter
to 0 enforces the chip flag NAND_NO_SUBPAGE_WRITE, effectively disabling
subpage writes.
The experimental procedure and logs are detailed below, covering tests
on both real Macronix NAND flash and the nandsim simulated flash, each
tested with and without subpage support enabled. Additionally, when
subpage support is enabled, testing of the vid_hdr_shift performed.
