Hi,The swiotlb messages have been introduced by this upstream commits, which has been backported in various stable branches: commit 8396c793ffdf28bb8aee7cfe0891080f8cab7890 Author: Sam Protsenko <semen.protse...@linaro.org> Date: Wed Mar 6 17:20:52 2024 -0600 mmc: dw_mmc: Fix IDMAC operation with pages bigger than 4K You can try to build a kernel with it reverted to see if it also fixes the corruption issue. In the meantime, I am working on a patch.
Nice! I saw your patch, and I'm going to test it in a day or two (I have an unrelated $dayjob). I'll let you know.
Previously on this thread...
Hmm I am actually surprised that you are able to boot your system with so many corruption. As the characters seems duplicated and the emmc bus is a 8-bit one, it could be a timing issue between the emmc and the controller. One thing to try is lowering the speed by removing the highspeed capabilities from the device tree.
It worked! No more corruption. Lowering the speed doesn't have too much performance impact: using a simple dd test with bs=1M: before: 28MB/s, after: 20MB/s. The emmc chip is bought from orange pi, said to be capable of HS400, and it runs great as the boot drive for cfarm423.cfarm.net. So the throughput seems to be severely limited by CPU, and it's a small price to pay comparing to data corruption.
I do have another Pine64 Star64 8GB board. If you want to make a patch to send to upstream, I can test on Star64 as well, since cap-mmc-highspeed and mmc-hs200-1_8v are in jh7110-common.dtsi, and it will affect Star64 and Milk-V Mars too (but I don't have a Milk-V Mars board).
Lemme paste 3 pieces of kernel log here. mmcblk0 is the emmc here.(unrelated: "Freeing initrd memory: 49556K" somehow takes more than 10 seconds on this board)
