Hi Guys, Any updates to support Intel P-core + E-core? I have filed a bug: PR 261169<https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=261169>, but no updates. Does anybody know the progress?
For Intel Adler Lake P core + E core processor (i7-12700T), copying files to FAT32 partition, the file corrupted (50%), but ZFS is fine. After disabling E core in the code by restrict the max cpu number, this issue is gone. And No E core processor has no such issue, like i7-12400. HW ENV: CPU: Intel AlderLake 12th Gen i7-12700T Disk: NVME SSD There are 3 methods to reproduce this issue: 1. Make FreeBSD 13 USB disk installer, install FreeBSD with UFS, and select install source and ports, the txz package checking will be failed. 2. Boot to shell by USB disk installer, and mount a FAT32 partition (on SSD), and copy a 300MB file to the FAT32, compare the sha256 checksums for the source file and the dst file, the checksum are different (50%). Or if there is a 300MB file in FAT32 partition, mount the partition, and for the first time check the sha256 value by running 'sha256 file.tgz', the checksum is wrong, but the second time, the checksum is correct. 3. Install FreeBSD 13 with ZFS, and it can work well. And boot into FreeBSD, disable swap, and format the SWAP partition to FAT32. Do the testing as above.
