Hy Timo ! I Made some modification in stream_read in zlib. I remove all zlib part, because i don't need this, but i need to read a istream to change it. Well, i create a size_t called supersize, with is a substitute for stream->zs.avail_in. The trouble is, my debug file have a lot of "READ Plugin\n", and i think it's because my read becomes a loop, i think it's because

Does someone know where I could get my hands on an ima that's larger than 2.88meg... I use winimage for all my ima's and stuff but i'm having trouble configuring a custom size. If anyone has a large ima I could utilize that would be great, preferably one fitting this memdisk supported size: 3,932,160 bytes (3840K) c=80 h=2 s=48 3.5" DSED (extended) If not instructions on making

Below should be useful for some experiments Jason is doing. I thought I'd send it out for early review/feedback. Compiled-only at this point. event idx feature allows us to defer interrupts until a specific # of descriptors were used. Sometimes it might be useful to get an interrupt after a specific descriptor, regardless. This adds a descriptor flag for this, and an API to create an urgent

This patch adds support for the Mergeable Receive Buffers feature to vhost_net. +-DLS Changes from previous revision: 1) renamed: vhost_discard_vq_desc -> vhost_discard_desc vhost_get_heads -> vhost_get_desc_n vhost_get_vq_desc -> vhost_get_desc 2) added heads as argument to ghost_get_desc_n 3) changed "vq->heads" from iovec to vring_used_elem, removed casts 4)
