- 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) * lorenzo/pci/endpoint: PCI: endpoint: Create configfs entry for each pci_epf_device_id table entry misc: pci_endpoint_test: Use pci_irq_vector function PCI: endpoint: functions/pci-epf-test: Replace lower into upper case characters misc: pci_endpoint_test: Replace lower into upper case characters PCI: endpoint: Replace mdelay with usleep_range() in pci_epf_test_write()

misc: pci_endpoint_test: Use pci_irq_vector function

2018-05-15T15:19:35+00:00

Replace "pdev->irq + index" operation by the pci_irq_vector() call, that converts from device vector to Linux IRQ. Suggested-by: Alan Douglas Signed-off-by: Gustavo Pimentel [lorenzo.pieralisi@arm.com: updated commit log] Signed-off-by: Lorenzo Pieralisi

misc: pci_endpoint_test: Add DesignWare EP entry

2018-05-15T14:54:40+00:00

Add the DesignWare EP device ID entry to pci_endpoint_test driver table. Allow the device to be recognized and handled by the pci_endpoint_test driver. Signed-off-by: Gustavo Pimentel Signed-off-by: Lorenzo Pieralisi Acked-by: Kishon Vijay Abraham I

misc: pci_endpoint_test: Replace lower into upper case characters

2018-05-15T14:12:58+00:00

Replace all initial lower case character into upper case in comments and debug printks. Signed-off-by: Gustavo Pimentel Signed-off-by: Lorenzo Pieralisi

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. pci 0000:01:00.0: BAR 4: assigned [mem 0xc0300000-0xc031ffff 64bit] pci 0000:01:00.0: BAR 2: assigned [mem 0xc0320000-0xc03203ff 64bit] pci 0000:01:00.0: BAR 0: assigned [mem 0xc0320400-0xc03204ff 64bit] pci-endpoint-test 0000:01:00.0: can't ioremap BAR 1: [??? 0x00000000 flags 0x0] pci-endpoint-test 0000:01:00.0: failed to read BAR1 pci-endpoint-test 0000:01:00.0: can't ioremap BAR 3: [??? 0x00000000 flags 0x0] pci-endpoint-test 0000:01:00.0: failed to read BAR3 pci-endpoint-test 0000:01:00.0: can't ioremap BAR 5: [??? 0x00000000 flags 0x0] pci-endpoint-test 0000:01:00.0: failed to read BAR5 Signed-off-by: Niklas Cassel Signed-off-by: Lorenzo Pieralisi Acked-by: Kishon Vijay Abraham I

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(). Signed-off-by: Kishon Vijay Abraham I Signed-off-by: Bjorn Helgaas

misc: pci_endpoint_test: Fix pci_endpoint_test not releasing resources on remove

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

sscanf(misc_device->name, DRV_MODULE_NAME ".%d", &id) in pci_endpoint_test_remove() returns 0, which results in returning early without releasing the resources. This is as a result of misc_device not having a valid name. Fix it here. Signed-off-by: Kishon Vijay Abraham I Signed-off-by: Bjorn Helgaas

misc: pci_endpoint_test: Fix failure path return values in probe

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

Return value of pci_endpoint_test_probe is not set properly in a couple of failure cases. Fix it here. Signed-off-by: Kishon Vijay Abraham I Signed-off-by: Bjorn Helgaas

misc: pci_endpoint_test: Avoid triggering a BUG()

2017-10-31T20:33:39+00:00

If you call ida_simple_remove(&pci_endpoint_test_ida, id) with a negative "id" then it triggers an immediate BUG_ON(). Let's not allow that.

misc: pci_endpoint_test: Prevent some integer overflows

2017-10-17T18:56:20+00:00

"size + max" can have an arithmetic overflow when we're allocating: orig_src_addr = dma_alloc_coherent(dev, size + alignment, ... Add a few checks to prevent that.
