Hi all, If you take a look at the service.rb file in the win32-service repository (the new one in the toplevel repository path), I''ve got this bit of code, which succeeds, but I can''t seem to unpack the data structure properly. Did I pack it wrong to begin with? I should know this but I''m spacing out. proc_status = [0,0,0,0,0,0,0,0,0,0].pack(''LLLLLLLLLL'') enum_service = [0.chr, 0.chr].pack(''pp'') + proc_status service_buf = enum...

Currently the virtio_ring structure are not declared packed, but they describe an hardware like interface. We should not allow compilers to make alignments and optimizations that can be different between the guest and host compiler. I propose to declare all structures that are in shared memory as packed. Does anybody see a problem with packed? Signe...

The attached patch (gcc.patch) implements the gcc portion of packed types. I have only tested this on a few examples, so I may be missing some type conversions somewhere.

DMA-related logic is separated from the virtqueue_add_packed(). DMA address will be saved as sg->dma_address, then virtqueue_add_packed() will use it directly. Unmap operation will be simpler. The purpose of this is to facilitate subsequent support to receive dma address mapped by drivers. Signed-off-by: Xuan Zhuo <xuanzhuo at linux.alibaba.com>...

With Winetricks, Fruity Loops seems to be working well. The only thing that is not working right now is the packs. I can't figure out why the packs aren't working. If I click on the bass pack, it produces sound; if I click on one of the choir packs, no sound is produced. Linux reads the bass pack as pcm encoded. Linux isn't able to read all the packs that aren't working. I know that w...

...n algorithm, that would help a lot! I'm on a project in a retail corporation, working on a program to assist retail buyers in creating their orders. The program will be used internally, and not sold to other companies. In retail terms, the problem is to determine the best assortment of case packs to order for a given store, and given a set of desired quantities for each size of a product. A case pack is a set of sizes that the supplier assembles. The retailer must order in whole case packs. For example, For a given shoe style, in the color brown, a supplier has the following case packs...

DMA-related logic is separated from the virtqueue_add_vring_packed() to prepare for subsequent support for premapped. DMA address will be saved as sg->dma_address, then virtqueue_add_vring_packed() will use it directly. If it is a premapped scene, the transmitted sgs should have saved DMA address in dma_address, and in virtio core, we need to pass virtqueue...

In guest, the XDP program will return XDP_DROP directly. And in host, testpmd will do txonly fwd. When burst size is 1 and packet size is 64 in testpmd and testpmd needs to iterate 5 Tx queues (but only the first two queues are enabled) to prepare and inject packets, I got ~12% performance boost (5.7Mpps -> 6.4Mpps). And if the vhost PMD is faster (e.g. just need to iterate the first two queues to prepare and inject pack...

Is there any particular reason why ov_read() packs floats to integer PCM inline, rather than being implemented in terms of ov_read_float() and a separate packing fucntion? There are obviously many advantages doing audio manipulation on the floats before packing, but right now you have to reinvent the packing stage yourself - in a replaygain...
