| Platform Mocking |
| ================ |
| |
| This file documents *platform mocking*, mocking libraries that mock out platform |
| specific features and aid in writing mocks for platform drivers and other low |
| level kernel code. |
| |
| Enable Platform Mocking |
| ----------------------- |
| ``CONFIG_PLATFORM_MOCK`` needs to be added to the .config (or kunitconfig) to |
| enable platform mocking. |
| |
| Mocked IO Functions |
| ------------------- |
| The following functions have been mocked for convenience. |
| |
| .. code-block:: c |
| |
| u8 readb(const volatile void __iomem *); |
| u16 readw(const volatile void __iomem *); |
| u32 readl(const volatile void __iomem *); |
| u64 readq(const volatile void __iomem *); |
| void writeb(u8, const volatile void __iomem *); |
| void writew(u16, const volatile void __iomem *); |
| void writel(u32, const volatile void __iomem *); |
| void writeq(u64, const volatile void __iomem *); |
| |
| .. note:: These functions do not have any non-mocked behaviour in UML. |
