PCI_DOE_MAX_LENGTH macro can be used outside the PCI core as well, hence move the macro to include/linux/pci-doe.h. These changes prepare the groundwork for the DOE endpoint implementation that will reuse these common definitions.

Changes since v1: - Moved the common macros that need not be visible outside the PCI core to drivers/pci/pci.h instead to include/linux/pci-doe.h as suggested by Lukas Wunner - Removed the redundant empty inlines guarded with CONFIG_PCI_DOE in include/linux/pci-doe.h. v3: https://lore.kernel.org/all/20260427051725.223704-2-a-garg7@ti.com/ v2: https://lore.kernel.org/all/20260401073022.215805-2-a-garg7@ti.com/ v1: https://lore.kernel.org/all/20260213123603.420941-3-a-garg7@ti.com/ drivers/pci/doe.c | 11 ----------- drivers/pci/pci.h | 9 +++++++++ include/linux/pci-doe.h | 3 +++ 3 files changed, 12 insertions(+), 11 deletions(-) diff --git a/drivers/pci/doe.c b/drivers/pci/doe.c index 7b41da4ec11a..e8d9e95644b3 100644 --- a/drivers/pci/doe.c +++ b/drivers/pci/doe.c @@ -28,12 +28,6 @@ #define PCI_DOE_TIMEOUT HZ #define PCI_DOE_POLL_INTERVAL (PCI_DOE_TIMEOUT / 128) -#define PCI_DOE_FLAG_CANCEL 0 -#define PCI_DOE_FLAG_DEAD 1 - -/* Max data object length is 2^18 dwords */ -#define PCI_DOE_MAX_LENGTH (1 << 18) - /** * struct pci_doe_mb - State for a single DOE mailbox * @@ -63,11 +57,6 @@ struct pci_doe_mb { #endif }; -struct pci_doe_feature { - u16 vid; - u8 type; -}; - /** * struct pci_doe_task - represents a single query/response * diff --git a/drivers/pci/pci.h b/drivers/pci/pci.h index 4a14f88e543a..5844deee2b5f 100644 --- a/drivers/pci/pci.h +++ b/drivers/pci/pci.h @@ -683,6 +683,15 @@ struct pci_sriov { bool drivers_autoprobe; /* Auto probing of VFs by driver */ }; +/* DOE Mailbox state flags */ +#define PCI_DOE_FLAG_CANCEL 0 +#define PCI_DOE_FLAG_DEAD 1 + +struct pci_doe_feature { + u16 vid; + u8 type; +}; + #ifdef CONFIG_PCI_DOE void pci_doe_init(struct pci_dev *pdev); void pci_doe_destroy(struct pci_dev *pdev); diff --git a/include/linux/pci-doe.h b/include/linux/pci-doe.h index bd4346a7c4e7..abb9b7ae8029 100644 --- a/include/linux/pci-doe.h +++ b/include/linux/pci-doe.h @@ -19,6 +19,9 @@ struct pci_doe_mb; #define PCI_DOE_FEATURE_CMA 1 #define PCI_DOE_FEATURE_SSESSION 2 +/* Max data object length is 2^18 dwords */ +#define PCI_DOE_MAX_LENGTH (1 << 18) + struct pci_doe_mb *pci_find_doe_mailbox(struct pci_dev *pdev, u16 vendor, u8 type); -- 2.34.1
