Hi, I do not have much to report for this week. I was on holiday from 31 May to 2 June. During the rest of the week, I worked on finishing up my implementation of the xen-specific bus_dma(9) methods before submitting them for initial review. I believe it would be complete and finished up by the time first evaluations roll around, June 11. I figured out a workaround for a major problem I was facing: in xen_bus_dmamap_load(), my implementation made it impossible for the drivers using the method to specify a callback. I fixed/worked around the problem by using a struct to hold the callback function pointer and the callback arg of the client, and pass it to bus_dmamap_load(). Take a look at [0] for reference. I also implemented xen_bus_dmamap_load_mbuf() [3]. Other than this, I fixed a bunch of minor bugs/errors. They are too small and too many to mention here. Take a look at my GitHub repository [1] if you are interested. I maintain a blog on Blogger where I publish my progress every few days. Check it out if you want more details on what I'm doing [2].
