eigenform @reflexive.space · 03/09/2026i see, the whole thing about "no hardware support for MTE on the Pixel 11" was just a misunderstanding about the fact that Linux emulates the feature registers and sets ID_AA64PFR1_EL1.MTE to zero when you boot with `arm64.nomte`, doh 🤦 061

eigenform @reflexive.space · 30/08/2026TIL there's a paper about the Ampere MTE implementation that gives a pretty good overview of some pain points (and presumably it's worse when everything has to be low-power!) arxiv.org/pdf/2511.177...arxiv.org 111

eigenform @reflexive.space · 15/08/2026like, if the mmio writes are nonposted hypertransport transactions (*always* ordered wrt each other, and they impose order on the queue of posted transactions), you expect the aliasing load/store in the middle is not allowed to start before the mmio write is complete? ¯\_(ツ)_/¯ 110
eigenform @reflexive.space · 15/08/2026i think it means "posted to hypertransport queue where younger transactions are [generally] allowed to start before responses to older transactions" but yeah, its not clear to me how that affects what happens in the CPU's load/store queue inbetween those mfences!! 110
eigenform @reflexive.space · 15/08/2026i feel like this should always be ordered correctly? so the thing happening here is really just "make very sure there are no pending transactions, toggle the mappings for a very brief time, make sure only one load/store escapes"? cc @there.is.no.aarch64.mov 100
eigenform @reflexive.space · 15/08/2026(i guess i just cant tell if the whole thing depends on some hypertransport weirdness) 110
