Hi I was hoping this might land for 6.5-rc1, is there a new version that might apply against 6.5? Cheers Mike On Tue, 9 May 2023 at 08:32, Greg Kroah-Hartman wrote: > > On Tue, May 09, 2023 at 09:16:35AM +0200, Petr Tesařík wrote: > > On Wed, 26 Apr 2023 14:44:39 +0200 > > Petr Tesařík wrote:

Hi I've not had any issues since using this, but I imagine most people won't know how to set swiotlb=dynamic if they start seeing this (when it lands) Any clue as to why this broke last cycle? Thanks Mike On Fri, 28 Apr 2023 at 10:07, Petr Tesařík wrote: > > On Fri, 28 Apr 2023 09:53:38 +0100

[PATCH v2 0/7] Allow dynamic allocation of software IO TLB bounce buffers

2023-04-19 Thread Petr Tesarik
From: Petr Tesarik The goal of my work is to provide more flexibility in the sizing of SWIOTLB. The software IO TLB was designed with these assumptions: 1. It would not be used much, especially on 64-bit systems. 2. A small fixed memory area (64 MiB by default) is sufficient to handle the fe
