Kind bump on this thread. As for me I'd like to attach nvme(4) and maybe ethernet and amdgpu(4) to the Thunderbolt-as-PCIe-bridge. Have a good wknd! Joseph ‐‐‐ Original Message ‐‐‐ On Monday, 26 October 2020 13:02, Joseph Mayer wrote: > (If this one belongs on misc@ please

Feature request: Use the PCIe devices on Thunderbolt (aka PCIe hotplug?)

2020-03-20 Thread Joseph Mayer
(Maybe to be moved to misc@) Dear OpenBSD tech@, Thunderbolt support would be awesome. Especially it would allow the use of additional M.2 NVMe SSD:s on a laptop at full performance. Thunderbolt support would also allow the use of an AMDGPU via a PCIe chassi, as well as enable the use of 10gbps

Hi Ben, To my best awareness, Power9 support is underway. No idea about date. Maybe usable in 4-12mo? Joseph On Wednesday, 6 November 2019 12:49, Ben Crowhurst wrote: > I've seen a few threads discussing OpenBSD on IBM Power Systems. >

Man page/doc/slides/books/specs re OpenBSD memory model or memory order?

Hi, This is not to suggest that the following would be relevant or needed: Is there any any man page, or documents, slides, books or standards specification documents regarding OpenBSD's memory model or memory order considerations? A marc.info misc@ or tech@ or Google search for query gives no

AMD64 buffer cache 4GB cap anything new, multiqueueing plans? ("64bit DMA on amd64" cont)

Hi, Previously there was a years-long thread about a 4GB (32bit) buffer cache constraint on AMD64, ref https://marc.info/?t=14682443664=1=2 . What I gather is, * The problematique is that on AMD64, DMA is limited to 32bit addressing, I guess because unlike AMD64 arch CPU:s which all

Hi Mike, About the GPDPocket laptop specifically, my best awareness is that its battery status reporting has been reported to be quirky, and that it might work in some BIOS versions and not in other. The GPDPocket's BIOS comes in two flavors, "unlocked" with more options and "locked" with less.
