[Bug 265786] broadcom storage controller: bus_dmamap_load_ccb() is failing with EINPROGRESS for 1MB IOs
Date: Fri, 12 Aug 2022 14:56:30 UTC
https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=265786 --- Comment #1 from Warner Losh <imp@FreeBSD.org> --- First, EINPROGRESS means that the transaction has been deferred either because the bounce pages it needs to allocate the memory backing the DMA isn't available (which I don't think is in play, but might be if there's a maximum address constraint for the dmamap) or there's not enough iommu contexts available to do the I/O. I'm having trouble recalling the exact context for my suggestion or the comment that the fix should be in 13.1. Can you refresh my recollection on that? -- You are receiving this mail because: You are the assignee for the bug.
