Fri, 22 Dec 2023 06:46:26 +0000

cdx: create sysfs bin files for cdx resourcesResource binary file contains the content of the memory regions.These resources devices can be used to mmap the MMIO regions inthe user-space.Co-developed-by: Puneet Gupta Signed-off-by: Puneet Gupta Signed-off-by: Abhijit Gangurde Link: https://lore.kernel.org/r/20231222064627.2828960-1-abhijit.gangurde@amd.comSigned-off-by: Greg Kroah-Hartman List of files: /linux-6.15/Documentation/ABI/testing/sysfs-bus-cdx

fa10f413 - cdx: add sysfs for subsystem, class and revision

Tue, 17 Oct 2023 16:05:05 +0000

cdx: add sysfs for subsystem, class and revisionCDX controller provides subsystem vendor, subsystem device, class andrevision info of the device along with vendor and device ID in nativeendian format. CDX Bus system uses this information to bind the cdxdevice to the cdx device driver.Co-developed-by: Puneet Gupta Signed-off-by: Puneet Gupta Co-developed-by: Nipun Gupta Signed-off-by: Nipun Gupta Signed-off-by: Abhijit Gangurde Reviewed-by: Pieter Jansen van Vuuren Tested-by: Nikhil Agarwal Link: https://lore.kernel.org/r/20231017160505.10640-8-abhijit.gangurde@amd.comSigned-off-by: Greg Kroah-Hartman List of files: /linux-6.15/Documentation/ABI/testing/sysfs-bus-cdx

e3cfd49c - cdx: add support for bus enable and disable

Tue, 17 Oct 2023 16:05:03 +0000

cdx: add support for bus enable and disableCDX bus needs to be disabled before updating/writing devicesin the FPGA. Once the devices are written, the bus shall berescanned. This change provides sysfs entry to enable/disable theCDX bus.Co-developed-by: Nipun Gupta Signed-off-by: Nipun Gupta Signed-off-by: Abhijit Gangurde Link: https://lore.kernel.org/r/20231017160505.10640-6-abhijit.gangurde@amd.comSigned-off-by: Greg Kroah-Hartman List of files: /linux-6.15/Documentation/ABI/testing/sysfs-bus-cdx

Mon, 13 Mar 2023 13:26:36 +0000

cdx: add device attributesCreate sysfs entry for CDX devices.Sysfs entries provided in each of the CDX device detected bythe CDX controller - vendor id - device id - remove - reset of the device. - driver overrideSigned-off-by: Puneet Gupta Signed-off-by: Nipun Gupta Signed-off-by: Tarak Reddy Reviewed-by: Pieter Jansen van Vuuren Tested-by: Nikhil Agarwal Link: https://lore.kernel.org/r/20230313132636.31850-8-nipun.gupta@amd.comSigned-off-by: Greg Kroah-Hartman List of files: /linux-6.15/Documentation/ABI/testing/sysfs-bus-cdx

2959ab24 - cdx: add the cdx bus driver

Mon, 13 Mar 2023 13:26:30 +0000

cdx: add the cdx bus driverIntroduce AMD CDX bus, which provides a mechanism for scanningand probing CDX devices. These devices are memory mapped onsystem bus for Application Processors(APUs).CDX devices can be changed dynamically in the Fabric and CDXbus interacts with CDX controller to rescan the bus andrediscover the devices.Signed-off-by: Nipun Gupta Reviewed-by: Pieter Jansen van Vuuren Tested-by: Nikhil Agarwal Link: https://lore.kernel.org/r/20230313132636.31850-2-nipun.gupta@amd.comSigned-off-by: Greg Kroah-Hartman List of files: /linux-6.15/Documentation/ABI/testing/sysfs-bus-cdx
