PCI: endpoint: Fix missing destroy_workqueue()

2021-05-22T08:59:43Z

[ Upstream commit acaef7981a218813e3617edb9c01837808de063c ] Add the missing destroy_workqueue() before return from pci_epf_test_init() in the error handling case and add destroy_workqueue() in pci_epf_test_exit(). Link: https://lore.kernel.org/r/20210331084012.2091010-1-yangyingliang@huawei.com Fixes: 349e7a85b25fa ("PCI: endpoint: functions: Add an EP function to test PCI") Reported-by: Hulk Robot Signed-off-by: Yang Yingliang Signed-off-by: Lorenzo Pieralisi Signed-off-by: Sasha Levin

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

2020-01-27T13:50:23Z

[ Upstream commit 726dabfde6aa35a4f1508e235ae37edbbf9fbc65 ] 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.

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.

PCI: endpoint: Make epc->ops->clear_bar()/pci_epc_clear_bar() take struct *epf_bar

2018-04-03T11:38:05Z

Make epc->ops->clear_bar()/pci_epc_clear_bar() take struct *epf_bar. This is needed so that epc->ops->clear_bar() can clear the BAR pair, if the BAR is 64-bits wide. This also makes it possible for pci_epc_clear_bar() to sanity check the flags. Signed-off-by: Niklas Cassel Signed-off-by: Lorenzo Pieralisi Reviewed-by: Gustavo Pimentel

PCI: endpoint: Handle 64-bit BARs properly

2018-04-03T11:38:04Z

If a 64-bit BAR was set-up, we need to skip a BAR, since a 64-bit BAR consists of a BAR pair. We need to check what BAR width the epc->ops->set_bar() specific implementation actually did set-up, since some drivers, like the Cadence EP controller, sometimes sets up a 64-bit BAR, even though a 32-bit BAR was requested.
