Subject: [PATCH v3 2/8] x86/iommu: iommu_igfx and iommu_qinval are Intel VT-d specific
Date: Mon, 16 Jan 2023 09:04:25 +0200 [thread overview]
Message-ID: <20230116070431.905594-3-burzalodowa@gmail.com> (raw)
In-Reply-To: <20230116070431.905594-1-burzalodowa@gmail.com>
Use CONFIG_INTEL_IOMMU to guard the usage of iommu_igfx and iommu_qinval
in common code.
No functional change intended.
Signed-off-by: Xenia Ragiadakou <burzalodowa@gmail.com>

Changes in v3:
- handle iommu_snoop case in a different patch and update commit msg
- use no_config_param() to print a warning when the user sets an INTEL_IOMMU
specific string in the iommu boot parameter and INTEL_IOMMU is disabled
