Remove optionality, always run tests in a suite even if one fails. This brings perf's test more inline with kunit that lacks this notion. Signed-off-by:

All tests now return TEST_SKIP if not supported. Removing this function brings perf's test_suite struct more inline with kunit. Signed-off-by:

Migrate the is_supported functionality to returning TEST_SKIP. Motivation is kunit has no is_supported function. Signed-off-by:

Add a test case struct mirroring the 'struct kunit_case'. Use the struct with the DEFINE_SUITE macro, where the single test is turned into a test case. Update the helpers in builtin-test to handle test cases. Signed-off-by:

Rather than export test functions, export the test struct. Rename with a suite__ prefix to avoid name collisions. Committer notes: Its '&suite__vectors_page', not '&suite__vectors_pages', noticed when cross building to arm (32-bit). Signed-off-by:

Ian Rogers authored
By switching to an array of pointers to tests (later to be suites) the definition of the tests can be moved to the file containing the tests. Committer notes: It's "&vectors_page", not "&vectors_pages", noticed when cross building to 32-bit ARM. Also the DEFINE_SUITE(vectors_page) should be done where its function is implemented, in tools/perf/arch/arm/tests/vectors-page.c, so that we can make it static, as we don't have anymore its declaration in tests.h.

Currently tests are setup in builtin-test with function pointers. Kunit exposes tests as a kunit_suite with a null terminated array of test cases. Use a macro to aid transition from one to the other in later changes. Signed-off-by:

SOL_SOCKET has a different value according to the architecture, some have it as 0xffff while all the others have it as 1, so a simple string array isn't usable, add a scnprintf routine that treats it as a special case, using the array for other values. Signed-off-by: -

Pull PCI fixes from Bjorn Helgaas: "Revert conversion to struct device.driver instead of struct pci_dev.driver. The device.driver is set earlier, and using it caused the PCI core to call driver PM entry points before .probe() and after .remove(), when the driver isn't prepared. This caused NULL pointer dereferences in i2c_designware_pci and probably other driver issues" * tag 'pci-v5.16-fixes-1' of git://git.kernel.org/pub/scm/linux/kernel/git/helgaas/pci: Revert "PCI: Use to_pci_driver() instead of pci_dev->driver" Revert "PCI: Remove struct pci_dev->driver"

This reverts commit 2a4d9408. Robert reported a NULL pointer dereference caused by the PCI core (local_pci_probe()) calling the i2c_designware_pci driver's .runtime_resume() method before the .probe() method. i2c_dw_pci_resume() depends on initialization done by i2c_dw_pci_probe(). Prior to 2a4d9408 ("PCI: Use to_pci_driver() instead of pci_dev->driver"), pci_pm_runtime_resume() avoided calling the .runtime_resume() method because pci_dev->driver had not been set yet. 2a4d9408 and b5f9c644 ("PCI: Remove struct pci_dev->driver"), removed pci_dev->driver, replacing it by device->driver, which *has* been set by this time, so pci_pm_runtime_resume() called the .runtime_resume() method when it previously had not.
