Subject: [PATCH v2 0/5] MTK NAND driver improvements and fixes
Date: Tue, 30 Apr 2019 18:02:45 +0800 [thread overview]
Message-ID: <20190430100250.28083-1-xiaolei.li@mediatek.com> (raw)
The following patch set mainly contains:
* Fix low level time calculation of read/write cycle to meet tRC_min
and tWC_min requirements.
* Refine RE# pulse width calculation and data sampling to improve read
performance.
* Add CS validity check.
* Fix oob buffer pointer wrongly setting and empty page threshold setting.
Changes on v2 relative to:
--------------------
tree : git://git.infradead.org/linux-mtd.git
branch : master
commit :
'commit 3e35730dd754 ("mtd: powernv_flash: Fix device
registration error")
Patch v2:
---------
- Fix type
- Reference correct faulty patch
- Refine code to do calculation and condition in separate steps
- Fix empty threshold calculation
Tests:
------
* ubifs and jffs2 are validated on NAND device MT29F16G08ADBCA by
'dd' command.
* all drivers/mtd/tests/* pass.
* speed test:
eraseblock write speed is 11087 KiB/s
eraseblock read speed is 19986 KiB/s
page write speed is 10689 KiB/s
page read speed is 18724 KiB/s
2 page write speed is 10611 KiB/s
2 page read speed is 18713 KiB/s
erase speed is 103696 KiB/s
2x multi-block erase speed is 354248 KiB/s
4x multi-block erase speed is 350459 KiB/s
8x multi-block erase speed is 356173 KiB/s
16x multi-block erase speed is 356173 KiB/s
32x multi-block erase speed is 358120 KiB/s
64x multi-block erase speed is 356173 KiB/s
