2437d5ea - dmaengine: make QCOM_HIDMA depend on HAS_IOMEM

Sat, 06 May 2023 11:16:28 +0000

dmaengine: make QCOM_HIDMA depend on HAS_IOMEMOn s390 systems (aka mainframes), it has classic channel devices fornetworking and permanent storage that are currently even more commonthan PCI devices. Hence it could have a fully functional s390 kernelwith CONFIG_PCI=n, then the relevant iomem mapping functions[including ioremap(), devm_ioremap(), etc.] are not available.Here let QCOM_HIDMA depend on HAS_IOMEM so that it won't be built tocause below compiling error if PCI is unset.--------------------------------------------------------ld: drivers/dma/qcom/hidma.o: in function `hidma_probe':hidma.c:(.text+0x4b46): undefined reference to `devm_ioremap_resource'ld: hidma.c:(.text+0x4b9e): undefined reference to `devm_ioremap_resource'make[1]: *** [scripts/Makefile.vmlinux:35: vmlinux] Error 1make: *** [Makefile:1264: vmlinux] Error 2Signed-off-by: Baoquan He Reviewed-by: Niklas Schnelle Cc: Andy Gross Cc: Bjorn Andersson Cc: Konrad Dybcio Cc: Vinod Koul Cc: linux-arm-msm@vger.kernel.orgCc: dmaengine@vger.kernel.orgReviewed-by: Dmitry Baryshkov Link: https://lore.kernel.org/r/20230506111628.712316-3-bhe@redhat.comSigned-off-by: Vinod Koul List of files: /linux-6.15/drivers/dma/qcom/Kconfig

5d0c3533 - dmaengine: qcom: Add GPI dma driver

Mon, 09 Nov 2020 08:54:50 +0000

dmaengine: qcom: Add GPI dma driverThis controller provides DMAengine capabilities for a variety of peripheralbuses such as I2C, UART, and SPI. By using GPI dmaengine driver, busdrivers can use a standardize interface that is protocol independent totransfer data between memory and peripheral.Link: https://lore.kernel.org/r/20201109085450.24843-4-vkoul@kernel.orgSigned-off-by: Vinod Koul List of files: /linux-6.15/drivers/dma/qcom/Kconfig

5c9f8c2d - dmaengine: qcom: Add ADM driver

Sat, 14 Nov 2020 14:02:33 +0000

dmaengine: qcom: Add ADM driverAdd the DMA engine driver for the QCOM Application Data Mover (ADM) DMAcontroller found in the MSM8x60 and IPQ/APQ8064 platforms.The ADM supports both memory to memory transactions and memoryto/from peripheral device transactions. The controller also providesflow control capabilities for transactions to/from peripheral devices.The initial release of this driver supports slave transfers to/fromperipherals and also incorporates CRCI (client rate control interface)flow control.The hardware only supports a 32 bit physical address, so specifying!PHYS_ADDR_T_64BIT gives maximum COMPILE_TEST coverage without having tospend effort on kludging things in the code that will never actually beneeded on real hardware.Signed-off-by: Andy Gross Signed-off-by: Thomas Pedersen Signed-off-by: Jonathan McDowell Link: https://lore.kernel.org/r/20201114140233.GM32650@earth.liSigned-off-by: Vinod Koul List of files: /linux-6.15/drivers/dma/qcom/Kconfig

a7f7f624 - treewide: replace '---help---' in Kconfig files with 'help'

Sat, 13 Jun 2020 16:50:22 +0000

treewide: replace '---help---' in Kconfig files with 'help'Since commit 84af7a6194e4 ("checkpatch: kconfig: prefer 'help' over'---help---'"), the number of '---help---' has been graduallydecreasing, but there are still more than 2400 instances.This commit finishes the conversion. While I touched the lines,I also fixed the indentation.There are a variety of indentation styles found. a) 4 spaces + '---help---' b) 7 spaces + '---help---' c) 8 spaces + '---help---' d) 1 space + 1 tab + '---help---' e) 1 tab + '---help---' (correct indentation) f) 1 tab + 1 space + '---help---' g) 1 tab + 2 spaces + '---help---'In order to convert all of them to 1 tab + 'help', I ran thefollowing commend: $ find . -name 'Kconfig*' | xargs sed -i 's/^[[:space:]]*---help---/\thelp/'Signed-off-by: Masahiro Yamada List of files: /linux-6.15/drivers/dma/qcom/Kconfig

dmaengine: add Qualcomm Technologies HIDMA channel driverThis patch adds support for hidma engine. The driver consists of twological blocks. The DMA engine interface and the low-level interface.The hardware only supports memcpy/memset and this driver only supportmemcpy interface.

dmaengine: add Qualcomm Technologies HIDMA management driverThe Qualcomm Technologies HIDMA device has been designed to supportvirtualization technology. The driver has been divided into two to followthe hardware design.1. HIDMA Management driver2. HIDMA Channel driverEach HIDMA HW consists of multiple channels. These channels share some setof common parameters. These parameters are initialized by the managementdriver during power up. Same management driver is used for monitoring theexecution of the channels. Management driver can change the performancebehavior dynamically such as bandwidth allocation and prioritization.The management driver is executed in host context and is the mainmanagement entity for all channels provided by the device.Signed-off-by: Sinan Kaya Reviewed-by: Andy Shevchenko Signed-off-by: Vinod Koul List of files: /linux-6.15/drivers/dma/qcom/Kconfig
