Really interesting suggestion. I was expecting something like cgroups, but bpf is certainly an option as well. How do you then use bpf to account the buffers? E.g. are you interacting with cgroups or have sysfs procedure to expose the list or how does that work? Additional to that why using DMA-buf for accounting in the first place? See DMA-buf is for sharing buffers and only a minimal fraction of buffers usually need to get shared.

E.g. are you interacting with cgroups or have sysfs procedure to expose the list or how does that work? Where currently we read through all of /sys/kernel/dmabuf/buffers/, with this we can load or pin a bpf program (like tools/testing/selftests/bpf/progs/dmabuf_iter.c) and then just cat (and parse) /sys/fs/bpf/dmabufs to get all per-buffer info one go. The attribution of buffers to processes is currently done by looking through procfs for fd and map references to dmabufs. That part is still slow, and provides no limitation on who can allocate how much, so I think cgroups is still the main potential tool for that. We have a program that does all the scanning work which is called on-demand for some use cases, and also manually by users: https://cs.android.com/android/platform/superproject/main/+/main:system/memory/libmeminfo/libdmabufinfo/tools/dmabuf_dump.cpp The per-buffer information is used for accounting kernel-only buffers that don't show up in procfs, and for partially mapped buffers without fd references where the total buffer size isn't otherwise known. Also sometimes (manual debugging or bugreports) it's useful just to know how much memory in total is tied up in dmabufs regardless of who allocated it because it can be gigabytes due to bugs or crazy program behaviors; the per buffer info is a faster way to get that then reading through all of procfs even if you assume everything is viewable in procfs. > Additional to that why using DMA-buf for accounting in the first place? See DMA-buf is for sharing buffers and only a minimal fraction of buffers usually need to get shared. Everything else is just massive overhead. Well we need some way to account all DMA-buf memory because it consumes a significant portion of total device memory. Even more so lately where they're used to store >1G AI models for execution on accelerator hardware. I've attached an example of dmabuf_dump output to give you an idea of how many buffers we're talking about, and most of those are (or will be, when an app goes to foreground) shared among multiple processes and/or drivers. > > While the kernel must have CONFIG_DEBUG_FS for > > the dmabuf_iter to be available, debugfs does not need to be mounted. > > The BPF program loaded by userspace that extracts per-buffer information > > gets to define its own interface which avoids the lack of ABI stability > > with debugfs (even if it were mounted). > > I think we can make the buffer list independent of CONFIG_DEBUG_FS. This would be nice. It's a fairly small overhead, and we can make it less with RCU too.
