The possible values go from 16MB -to 944MB, with a default of 64MB. This memory resides in the topmost -part of the lower 1GB memory area and grows bigger expanding towards the -begging of memory. - -It turns out that with low 'gpu_mem' values (16MB and 32MB) the size of -the memory available to the system in the lower 1GB area can outgrow the -interconnect's dma-range as its size was selected based on the maximum -system memory available given the default gpu_mem configuration. This -makes that memory slice unavailable for DMA. And may cause nasty kernel -warnings if CMA happens to include it. - -Change soc's dma-ranges to really reflect it's HW limitation, which is -being able to only DMA to the lower 1GB area. - -Fixes: 7dbe8c62ceeb ("ARM: dts: Add minimal Raspberry Pi 4 support") -Signed-off-by: Nicolas Saenz Julienne -Reviewed-by: Phil Elwell -Signed-off-by: Florian Fainelli ---- - arch/arm/boot/dts/bcm2711.dtsi | 2 +- - 1 file changed, 1 insertion(+), 1 deletion(-) - ---- a/arch/arm/boot/dts/bcm2711.dtsi -+++ b/arch/arm/boot/dts/bcm2711.dtsi -@@ -43,7 +43,7 @@ - <0x7c000000 0x0 0xfc000000 0x02000000>, - <0x40000000 0x0 0xff800000 0x00800000>;

The offset between physical memory +addresses and AMBA's view is provided by reading a PCI config register, +which is saved and used whenever DMA mapping is needed. + +It turns out that this DMA setup can be represented by properly setting +'dma_pfn_offset', 'dma_bus_mask' and 'dma_mask' during the PCI device +enable fixup. And ultimately allows us to get rid of this device's +custom DMA functions. + +Aside from the code deletion and DMA setup, sta2x11_pdev_to_mapping() is +moved to avoid warnings whenever CONFIG_PM is not enabled. + +Signed-off-by: Nicolas Saenz Julienne +Signed-off-by: Christoph Hellwig +--- + arch/x86/Kconfig | 1 - + arch/x86/include/asm/device.h | 3 - + arch/x86/include/asm/dma-direct.h | 9 -- + arch/x86/pci/sta2x11-fixup.c | 135 ++++++------------------------ + 4 files changed, 26 insertions(+), 122 deletions(-) + delete mode 100644 arch/x86/include/asm/dma-direct.h + +--- a/arch/x86/Kconfig ++++ b/arch/x86/Kconfig +@@ -708,7 +708,6 @@ config X86_SUPPORTS_MEMORY_FAILURE + config STA2X11 + bool "STA2X11 Companion Chip Support" + depends on X86_32_NON_STANDARD && PCI +- select ARCH_HAS_PHYS_TO_DMA + select SWIOTLB + select MFD_STA2X11 + select GPIOLIB +--- a/arch/x86/include/asm/device.h ++++ b/arch/x86/include/asm/device.h +@@ -6,9 +6,6 @@ struct dev_archdata { + #if defined(CONFIG_INTEL_IOMMU) || defined(CONFIG_AMD_IOMMU) + void *iommu;

If a portion of the viewport does not ++ * represent system memory -- e.g. 3GB of memory requires a 4GB ++ * viewport -- we can map the outbound memory in or after 3GB and even ++ * though the viewport will overlap the outbound memory the controller ++ * will know to send outbound memory downstream and everything else ++ * upstream. ++ * ++ * For example: ++ * ++ * - The best-case scenario, memory up to 3GB, is to place the inbound ++ * region in the first 4GB of pcie-space, as some legacy devices can ++ * only address 32bits. We would also like to put the MSI under 4GB ++ * as well, since some devices require a 32bit MSI target address. ++ * ++ * - If the system memory is 4GB or larger we cannot start the inbound ++ * region at location 0 (since we have to allow some space for ++ * outbound memory @ 3GB).

The -DMA mapping code is already aware of this and treats dev->bus_dma_mask -as a limit. This quirk is already used by some architectures although -still rare. - -With the introduction of the Raspberry Pi 4 we've found a new contender -for the use of bus DMA limits, as its PCIe bus can only address the -lower 3GB of memory (of a total of 4GB). This is impossible to represent -with a mask. To make things worse the device-tree code rounds non power -of two bus DMA limits to the next power of two, which is unacceptable in -this case. - -In the light of this, rename dev->bus_dma_mask to dev->bus_dma_limit all -over the tree and treat it as such. Note that dev->bus_dma_limit should -contain the higher accessible DMA address. - -Signed-off-by: Nicolas Saenz Julienne -Reviewed-by: Robin Murphy -Signed-off-by: Christoph Hellwig ---- - arch/mips/pci/fixup-sb1250.c | 16 ++++++++-------- - arch/powerpc/sysdev/fsl_pci.c | 6 +++--- - arch/x86/kernel/pci-dma.c | 2 +- - arch/x86/mm/mem_encrypt.c | 2 +- - arch/x86/pci/sta2x11-fixup.c | 2 +- - drivers/acpi/arm64/iort.c | 20 +++++++------------- - drivers/ata/ahci.c | 2 +- - drivers/iommu/dma-iommu.c | 3 +-- - drivers/of/device.c | 9 +++++---- - include/linux/device.h | 6 +++--- - include/linux/dma-direct.h | 2 +- - include/linux/dma-mapping.h | 2 +- - kernel/dma/direct.c | 27 +++++++++++++-------------- - 13 files changed, 46 insertions(+), 53 deletions(-) - ---- a/arch/mips/pci/fixup-sb1250.c -+++ b/arch/mips/pci/fixup-sb1250.c -@@ -21,22 +21,22 @@ DECLARE_PCI_FIXUP_EARLY(PCI_VENDOR_ID_SI - - /* - * The BCM1250, etc. PCI host bridge does not support DAC on its 32-bit -- * bus, so we set the bus's DMA mask accordingly.
