linux-toradex.git/drivers/gpu, branch v3.14.26 Linux kernel for Apalis and Colibri modules gpu/radeon: Set flag to indicate broken 64-bit MSI 2014-12-06T23:55:39+00:00 Benjamin Herrenschmidt benh@kernel.crashing.org 2014-10-03T05:18:59+00:00 a35b403e0ad0a6dfcbc4eb4d307d9d2aaa60d914 commit 91ed6fd2c383bb8f02d66e98b4a4d2f7207249dc upstream. Some radeon ASICs don't support all 64 address bits of MSIs despite advertising support for 64-bit MSIs in their configuration space. This breaks on systems such as IBM POWER7/8, where 64-bit MSIs can be assigned with some of the high address bits set. This makes use of the newly introduced "no_64bit_msi" flag in structure pci_dev to allow the MSI allocation code to fallback to 32-bit MSIs on those adapters. Adding Alex's review tag. Patch to the driver is identical to the reviewed one, I dropped the arch/powerpc hunk rewrote the subject and cset comment.

Some radeon ASICs don't support all 64 address bits of MSIs despite
advertising support for 64-bit MSIs in their configuration space.

This breaks on systems such as IBM POWER7/8, where 64-bit MSIs can
be assigned with some of the high address bits set.

This makes use of the newly introduced "no_64bit_msi" flag in structure
pci_dev to allow the MSI allocation code to fallback to 32-bit MSIs
on those adapters.

Adding Alex's review tag. Patch to the driver is identical to the
