2022-05-10fpga: dfl: Allow Port to be linked to FME's DFLMatthew Gerlach2-0/+10
Currently we use PORTn_OFFSET to locate PORT DFLs, and PORT DFLs are not connected FME DFL. But for some cases (e.g. Intel Open FPGA Stack device), PORT DFLs are connected to FME DFL directly, so we don't need to search PORT DFLs via PORTn_OFFSET again. If BAR value of PORTn_OFFSET is 0x7 (FME_PORT_OFST_BAR_SKIP) then driver will skip searching the DFL for that port. If BAR value is invalid, return -EINVAL.

Previously the feature IDs defined are unique, no matter which feature type. But currently we want to extend its usage to have a per-type feature ID space, so this patch adds feature type checking as well just before look into feature ID for different features which have irq info.

2022-01-25fpga: dfl: pci: Remove usage of the deprecated "pci-dma-compat.h" APIChristophe JAILLET1-10/+5
In [1], Christoph Hellwig has proposed to remove the wrappers in include/linux/pci-dma-compat.h. Some reasons why this API should be removed have been given by Julia Lawall in [2]. A coccinelle script has been used to perform the needed transformation. It can be found in [3]. It has been hand modified to use 'dma_set_mask_and_coherent()' instead of 'pci_set_dma_mask()/pci_set_consistent_dma_mask()' when applicable. This is less verbose. The explicit 'ret = -EIO;' has been removed because 'dma_set_mask_and_coherent()' returns 0 or -EIO, so its return code can be used directly.

DFL device drivers have a common need for checking feature revision information from the DFL header, as well as other common DFL information like the already exposed feature id and type. This patch exposes the feature revision information directly via the DFL device data structure. Since the DFL core code has already read the DFL header, this this patch saves additional mmio reads from DFL device drivers too.

This can create an issue incase the current designated cpu being used to collect fme pmu data got offline, as based on current code we are not migrating fme pmu to new target cpu. Because of that perf will still try to fetch data from that offline cpu and hence we will not get counter data.

The N5010 features an FPGA that manages/interfaces four QSFP ports, and allows on-board custom packet processing/filtering/routing, based on logic loaded with user-provided FPGA bitstreams. The N5011 cards adds a PCIe switch that exposes, in addition to the FPGA itself, two Intel E810 (aka Columbiaville) ethernet controllers. With this, packets can be forwarded from the FPGA to the host for further processing.

2021-07-21bus: Make remove callback return voidUwe Kleine-König1-3/+1
The driver core ignores the return value of this callback because there is only little it can do when a device disappears. This is the final bit of a long lasting cleanup quest where several buses were converted to also return void from their remove callback. Additionally some resource leaks were fixed that were caused by drivers returning an error code in the expectation that the driver won't go away. With struct bus_type::remove returning void it's prevented that newly implemented buses return an ignored error code and so don't anticipate wrong expectations for driver authors.
