Disk sector size & I/O size

Similarly, refer to #76. For ``bbssd`` mode, you also need to change the FTL level sector size to 4096B manually.

FEMU ocssd code issue

Good catch. Thanks for reporting this! Interested in submitting a patch to fix this? DEUBUG_OC20 is a typo :)

Computational Storage with SSD

Good question! There are different flavors of computational storage. Depending on your target workload or research you want to do, the simulation method might vary. A simple way to emulate...

I write few codes about FEMU ZNS controller-mapping, multi-channel and multi-way latency emulation

Thanks for the patch! This can be a nice addition to FEMU. Do you mind squashing all the commits into one and cleaning the code changes a little bit before...

I write few codes about FEMU ZNS controller-mapping, multi-channel and multi-way latency emulation

I will port your ZNS-related changes in another commit and discard changes to non-ZNS files. Thanks for the patch!

FEMU-SSD-size Setup

Your configuration seems ok to me. If you do a full-drive sequential write with 30720MB data, will it fail? If not, then it's ok to ignore the above FEMU error...

Are there cache and buffer in Blackbox Mode?

For this repo, as of now, the bbftl doesn't have a buffer implementation. We do have one for private use, I might spend some time merging it to the public...

Cannot write OCSSD2.0 of FEMU using SPDK

Thanks for reporting this. I will take a look later (need a while).

Cannot write OCSSD2.0 of FEMU using SPDK

Thanks for the updates. The OCSSD standard specifies its special physical read/write/erase commands for interacting with the device, not sure why SPDK deviates from this spec. Nice finding though. It...

Cannot write OCSSD2.0 of FEMU using SPDK

With the above patch, the SPDK FTL "hello world" test runs fine on FEMU.
