From 8a9208612eec8ddae4c418485d848ecfa0613699 Mon Sep 17 00:00:00 2001 From: Anton Kling Date: Mon, 30 Oct 2023 22:12:14 +0100 Subject: Meta: Move kernel and userland to their own folders. This is to allow both the kernel and the userland to share certain header files and to make the folder structure a bit more clear. --- kernel/drivers/pci.h | 26 ++++++++++++++++++++++++++ 1 file changed, 26 insertions(+) create mode 100644 kernel/drivers/pci.h (limited to 'kernel/drivers/pci.h') diff --git a/kernel/drivers/pci.h b/kernel/drivers/pci.h new file mode 100644 index 0000000..7511cee --- /dev/null +++ b/kernel/drivers/pci.h @@ -0,0 +1,26 @@ +#include + +struct GENERAL_DEVICE { + uint32_t base_mem_io; + uint8_t interrupt_line; +}; + +struct PCI_DEVICE { + uint16_t vendor; + uint16_t device; + uint8_t bus; + uint8_t slot; + union { + struct GENERAL_DEVICE gen; + }; +}; + +uint32_t pci_config_read32(const struct PCI_DEVICE *device, uint8_t func, + uint8_t offset); +void pci_config_write32(const struct PCI_DEVICE *device, uint8_t func, + uint8_t offset, uint32_t data); + +int pci_populate_device_struct(uint16_t vendor, uint16_t device, + struct PCI_DEVICE *pci_device); + +uint8_t pci_get_interrupt_line(const struct PCI_DEVICE *device); -- cgit v1.2.3
