Subject: [Nouveau] [PATCH 8/8] iommu/s390: Push the gfp parameter to the kmem_cache_alloc()'s
Date: Fri, 6 Jan 2023 12:42:48 -0400 [thread overview]
Message-ID: <8-v1-6e8b3997c46d+89e-iommu_map_gfp_jgg@nvidia.com> (raw)
In-Reply-To: <0-v1-6e8b3997c46d+89e-iommu_map_gfp_jgg@nvidia.com>
dma_alloc_cpu_table() and dma_alloc_page_table() are eventually called by
iommufd through s390_iommu_map_pages() and it should not be forced to
atomic. Thread the gfp parameter through the call chain starting from
s390_iommu_map_pages().

Subject: [PATCH 8/8] iommu/s390: Push the gfp parameter to the kmem_cache_alloc()'s
Date: Fri, 6 Jan 2023 12:42:48 -0400 [thread overview]
Message-ID: <8-v1-6e8b3997c46d+89e-iommu_map_gfp_jgg@nvidia.com> (raw)
In-Reply-To: <0-v1-6e8b3997c46d+89e-iommu_map_gfp_jgg@nvidia.com>
dma_alloc_cpu_table() and dma_alloc_page_table() are eventually called by
iommufd through s390_iommu_map_pages() and it should not be forced to
atomic. Thread the gfp parameter through the call chain starting from
s390_iommu_map_pages().

Subject: [PATCH 8/8] iommu/s390: Push the gfp parameter to the kmem_cache_alloc()'s
Date: Fri, 6 Jan 2023 12:42:48 -0400 [thread overview]
Message-ID: <8-v1-6e8b3997c46d+89e-iommu_map_gfp_jgg@nvidia.com> (raw)
In-Reply-To: <0-v1-6e8b3997c46d+89e-iommu_map_gfp_jgg@nvidia.com>
dma_alloc_cpu_table() and dma_alloc_page_table() are eventually called by
iommufd through s390_iommu_map_pages() and it should not be forced to
atomic. Thread the gfp parameter through the call chain starting from
s390_iommu_map_pages().
Signed-off-by: Jason Gunthorpe <jgg@nvidia.com>
