Hi @huaqianli. Please change the maintainer to yourself or someone from the IOT2050 team (as this is a fork of my original PoC). We really should try to get that into Debian Trixie before the window closes. There is already a RFP. I can try to upstream if it is worth it. Just let me know.
edit Just re-read my comment below: This package is abandoned, so we should really try to get rid of the dependency.

Thanks for your kind suggestion. I am bound to considering it carefully.

Have already replied to the filed bug report. However, the RFP was issued in 2017 and has not received a response yet.

Reserve a 64M memory region and ensure that all PCI devices do their DMA only inside that region. This is configured via a restricted-dma-pool and enforced with the help of the first PVU. Applying this isolation is not totally free in terms of overhead and memory consumption. It makes only sense for variants that support secure booting, and generally only when this is actually enable. Therefore model it as overlay that can be activated on demand. The firmware will take care of this via DT fixup during boot and will also provide a way to adjust the pool size.

The AM654 lacks an IOMMU, thus does not support isolating DMA requests from untrusted PCI devices to selected memory regions this way. Use static PVU-based protection instead. For this, we use the availability of restricted-dma-pool memory regions as trigger and register those as valid DMA targets with the PVU. In addition, we need to enable the mapping of requester IDs to VirtIDs in the PCI RC. We only use a single VirtID so far, catching all devices. This may be extended later on.

This commit adds support for device tree overlays for the IOT2050 Advanced PG2 and SM variants. These overlays enable DMA isolation, allowing for more flexible and secure memory management. Signed-off-by: Li Hua Qian <[email protected]>
This commit integrates the following main components into image: - hailo-pci (OSS kernel module) - hailo-firmware (proprietary firmware for hailo8 chip) - hailort (Userspace Libraries) - hailortcli (tool) - hailort (service) - libhailort (c library) - libhailort-dev (dev package) - python3-hailort (python library) - libgsthailo (gstreamer element) Signed-off-by: Li Hua Qian <[email protected]>
PVU-based DMA isolation brings SWIO TLB to the table and the maximum allowable number of contiguous slabs to map is 128 by default, but meta-hailo requires more than 128. Hence increase it to 256 when meta-hailo is included. Signed-off-by: Li Hua Qian <[email protected]>
Hailort 4.18 requires the version of numpy to be 1.23.3, otherwise the pyhailort will not work correctly. Signed-off-by: Li Hua Qian <[email protected]>
