clk: explicitly disable CONFIG_UML_PCI_OVER_VIRTIO in .kunitconfig

2022-07-14T16:35:44Z

CONFIG_UML_PCI_OVER_VIRTIO=y is needed to enable CONFIG_PCI=y on UML. However, this causes test failures when running the clk tests, i.e. $ ./tools/testing/kunit/kunit.py run --kunitconfig=drivers/clk A snippet of the particular error is: > ok 1 - clk_gate_test_parent_rate > ------------[ cut here ]------------ > WARNING: CPU: 0 PID: 45 at lib/logic_iomem.c:141 __raw_readl+0x9f/0xd0 This is triggered by this cast in the test: 143 ctx->fake_mem = (void __force __iomem *)&ctx->fake_reg; this seems to work except when logic iomem is enabled, i.e. CONFIG_INDIRECT_IOMEM=y. As a short-term fix, explicitly disable CONFIG_UML_PCI_OVER_VIRTIO in drivers/clk/.kunitconfig so we can enable it for everyone else by default in kunit.py. The long-term fix probably requires something more complicated, like #ifdef CONFIG_INDIRECT_IOMEM logic_iomem_add_region(...); #endif Signed-off-by: Daniel Latypov Reported-by: Maxime Ripard Tested-by: Maxime Ripard Acked-by: Stephen Boyd Reviewed-by: David Gow Acked-by: Brendan Higgins Signed-off-by: Shuah Khan
