Fixes: 4a60406d3592 ("driver core: platform: expose numa_node to users in s= ysfs") Cc: stable@vger.kernel.org Reported-by: kernel test robot Closes: https://lore.kernel.org/oe-kbuild-all/202309122309.mbxAnAIe-lkp@int= el.com/ Signed-off-by: Jinhui Guo --- V6 -> V7 1. Fix bug directly by adding numa_node to struct platform_device_info (suggested by Rafael J. Wysocki). 2. Remove reviewer name. V5 -> V6: 1. Update subject to correct function name platform_device_add(). 2. Provide a more clear and accurate description of the changes made in commit (suggested by Rafael J. Wysocki). 3. Add reviewer name. V4 -> V5: Add Cc: stable line and changes from the previous submited patches. V3 -> V4: Refactor code to be an ACPI function call (suggested by Greg Kroah-Hartma= n). V2 -> V3: Fix Signed-off name. V1 -> V2: Fix compile error without enabling CONFIG_ACPI. --- drivers/acpi/acpi_platform.c | 5 ++--- drivers/base/platform.c | 4 ++++ include/linux/platform_device.h | 26 ++++++++++++++++++++++++++ 3 files changed, 32 insertions(+), 3 deletions(-) diff --git a/drivers/acpi/acpi_platform.c b/drivers/acpi/acpi_platform.c index 48d15dd785f6..1ae7449f70dc 100644 --- a/drivers/acpi/acpi_platform.c +++ b/drivers/acpi/acpi_platform.c @@ -168,6 +168,7 @@ struct platform_device *acpi_create_platform_device(str= uct acpi_device *adev, pdevinfo.num_res =3D count; pdevinfo.fwnode =3D acpi_fwnode_handle(adev); pdevinfo.properties =3D properties; + platform_devinfo_set_node(&pdevinfo, acpi_get_node(adev->handle)); =20 if (acpi_dma_supported(adev)) pdevinfo.dma_mask =3D DMA_BIT_MASK(32); @@ -178,11 +179,9 @@ struct platform_device *acpi_create_platform_device(st= ruct acpi_device *adev, if (IS_ERR(pdev)) dev_err(&adev->dev, "platform device creation failed: %ld\n", PTR_ERR(pdev)); - else { - set_dev_node(&pdev->dev, acpi_get_node(adev->handle)); + else dev_dbg(&adev->dev, "created platform device %s\n", dev_name(&pdev->dev)); - } =20 kfree(resources); =20 diff --git a/drivers/base/platform.c b/drivers/base/platform.c index 76bfcba25003..c733bfb26149 100644 --- a/drivers/base/platform.c +++ b/drivers/base/platform.c @@ -808,6 +808,7 @@ struct platform_device *platform_device_register_full( { int ret; struct platform_device *pdev; + int numa_node =3D platform_devinfo_get_node(pdevinfo); =20 pdev =3D platform_device_alloc(pdevinfo->name, pdevinfo->id); if (!pdev) @@ -841,6 +842,9 @@ struct platform_device *platform_device_register_full( goto err; } =20 + if (numa_node >=3D 0) + set_dev_node(&pdev->dev, numa_node); + ret =3D platform_device_add(pdev); if (ret) { err: diff --git a/include/linux/platform_device.h b/include/linux/platform_devic= e.h index 7a41c72c1959..78e11b79f1af 100644 --- a/include/linux/platform_device.h +++ b/include/linux/platform_device.h @@ -132,10 +132,36 @@ struct platform_device_info { u64 dma_mask; =20 const struct property_entry *properties; + +#ifdef CONFIG_NUMA + int numa_node; /* NUMA node this platform device is close to plus 1 */ +#endif }; extern struct platform_device *platform_device_register_full( const struct platform_device_info *pdevinfo); =20 +#ifdef CONFIG_NUMA +static inline int platform_devinfo_get_node(const struct platform_device_i= nfo *pdevinfo) +{ + return pdevinfo ? pdevinfo->numa_node - 1 : NUMA_NO_NODE; +} + +static inline void platform_devinfo_set_node(struct platform_device_info *= pdevinfo, + int node) +{ + pdevinfo->numa_node =3D node + 1; +} +#else +static inline int platform_devinfo_get_node(const struct platform_device_i= nfo *pdevinfo) +{ + return NUMA_NO_NODE; +} + +static inline void platform_devinfo_set_node(struct platform_device_info *= pdevinfo, + int node) +{} +#endif + /** * platform_device_register_resndata - add a platform-level device with * resources and platform-specific data --=20 2.20.1
