Only one qpair is used for reading, which is rather inefficient. We currently allocate a bounce buffer for every allocation, which is also inefficient, due to the fact that we must read an integer multiple of LBAs. But it does work, and it is actually reasonably fast, even on an emulated machine using a spinning-disk-backed NVMe device (88MB/s.) I wasn't able to get it working in non-packaged, though; the device manager called supports_device() on a number of PCI devices, but not the NVMe device, so I have a different version with a hack that grabs the PCI info manually. I didn't test inside haiku.hpkg yet; perhaps it will work in there.
Haiku
Homepage | Mailing Lists | IRC Channels | Issue Tracker | API docs
Haiku is an open-source operating system that specifically targets personal computing. Inspired by the BeOS, Haiku is fast, simple to use, easy to learn and yet very powerful.
Goals
- Sensible defaults with minimal configuration required.
- Clean, clear, concise code.
- Unified desktop environment.
Trying Haiku
Haiku provides pre-built nightly images and release images. Haiku is compatible with a large variety of hardware, but in case you don't want to "take the plunge" and install Haiku on bare metal, you can install it on a virtual machine (VM) instead. If you've never used a VM before, you can follow one of the "Emulating Haiku" guides.
