pci_endpoint_test: Add 2 ioctl commands

2018-07-19T10:46:57+00:00

Add MSI-X support and update driver documentation accordingly.

Add 2 new IOCTL commands:
 - Allow to reconfigure driver IRQ type in runtime.
 - Allow to retrieve current driver IRQ type configured.

Add IRQ type validation before executing the READ/WRITE/COPY tests.

pci-epf-test/pci_endpoint_test: Cleanup PCI_ENDPOINT_TEST memspace

2018-07-19T10:39:44+00:00

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.

  - use usleep() instead of mdelay() in endpoint test (Jia-Ju Bai)

  - add configfs entries for pci_epf_driver device IDs (Kishon Vijay
    Abraham I)

  - clean up pci_endpoint_test driver (Gustavo Pimentel)

Replace "pdev->irq + index" operation by the pci_irq_vector() call,
that converts from device vector to Linux IRQ.

misc: pci_endpoint_test: Handle 64-bit BARs properly

2018-04-03T11:38:06+00:00

A 64-bit BAR consists of a BAR pair, where the second BAR has the
upper bits, so we cannot simply call pci_ioremap_bar() on every single
BAR index.

The second BAR in a BAR pair will not have the IORESOURCE_MEM resource
flag set. Only call ioremap on BARs that have the IORESOURCE_MEM
resource flag set.

misc: pci_endpoint_test: Fix BUG_ON error during pci_disable_msi()

2017-10-31T20:33:46+00:00

pci_disable_msi() throws a Kernel BUG if the driver has successfully
requested an IRQ and not released it. Fix it here by freeing IRQs before
invoking pci_disable_msi().
