PCI: pci-epf-test: Use pci_epc_get_features() to get EPC features

2019-02-15T10:01:16Z

Use pci_epc_get_features() to get EPC features such as linkup notifier support, MSI/MSIX capable, BAR configuration etc and use it for configuring pci-epf-test. Since these features are now obtained directly from EPC driver, remove pci_epf_test_data which was initially added to have EPC features in endpoint function driver.

PCI: pci-epf-test: Do not allocate next BARs memory if current BAR is 64Bit

2019-02-15T10:00:18Z

It's useless to allocate memory for next BAR if the current BAR is a 64Bit BAR. Stop allocating memory for the next BAR, if the current BARs flag indicates this is a 64Bit BAR. Tested-by: Gustavo Pimentel Signed-off-by: Kishon Vijay Abraham I Signed-off-by: Lorenzo Pieralisi

PCI: pci-epf-test: Remove setting epf_bar flags in function driver

2019-02-15T10:00:09Z

Now that pci_epf_alloc_space() sets BAR MEM TYPE flags as 64Bit or 32Bit based on size, remove setting it in function driver. Tested-by: Gustavo Pimentel Signed-off-by: Kishon Vijay Abraham I Signed-off-by: Lorenzo Pieralisi

PCI: endpoint: functions: Use memcpy_fromio()/memcpy_toio()

2019-02-13T09:50:58Z

Functions copying from/to IO addresses should use the memcpy_fromio()/memcpy_toio() API rather than plain memcpy(). Fix the issue detected through the sparse tool.

Add MSI-X support and update driver documentation accordingly. Signed-off-by: Gustavo Pimentel Signed-off-by: Lorenzo Pieralisi Acked-by: Kishon Vijay Abraham I

pci-epf-test/pci_endpoint_test: Cleanup PCI_ENDPOINT_TEST memspace

2018-07-19T10:39:44Z

Cleanup PCI_ENDPOINT_TEST memspace (by moving the interrupt number away from command section). Add IRQ_TYPE register to identify the triggered ID interrupt required for the READ/WRITE/COPY tests and raise IRQ test commands. Update documentation accordingly.

PCI: dwc: Add support for EP mode

2018-05-15T14:51:38Z

The PCIe controller dual mode is capable of operating in Root Complex (RC) mode as well as EP mode by configuration option. Add EP support to the DesignWare driver on top of RC mode support. Add new property on pci_epc structure which allow to configure pci_epf_test driver accordingly to the controller specific requirements.

PCI: endpoint: Replace mdelay with usleep_range() in pci_epf_test_write()

2018-05-08T10:13:42Z

pci_epf_test_write() is never called in atomic context. The call chain ending up at pci_epf_test_write() is: [1] pci_epf_test_write() <- pci_epf_test_cmd_handler() pci_epf_test_cmd_handler() is set as a parameter of INIT_DELAYED_WORK() in pci_epf_test_probe(). This function is not called in atomic context. Despite never getting called from atomic context, pci_epf_test_write() calls mdelay() to busy wait. This is not necessary and can be replaced with usleep_range() to avoid busy waiting.
