From ec249dd860ed88e15b3e2bd363cbfc76ba8c1884 Mon Sep 17 00:00:00 2001 From: Michael Neuling Date: Wed, 27 May 2015 16:07:16 +1000 Subject: cxl: Move include file cxl.h -> cxl-base.h This moves the current include file from cxl.h -> cxl-base.h. This current include file is used only to pass information between the base driver that needs to be built into the kernel and the cxl module. This is to make way for a new include/misc/cxl.h which will contain just the kernel API for other driver to use Signed-off-by: Michael Neuling Acked-by: Ian Munsie Signed-off-by: Michael Ellerman --- include/misc/cxl-base.h | 48 ++++++++++++++++++++++++++++++++++++++++++++++++ include/misc/cxl.h | 48 ------------------------------------------------ 2 files changed, 48 insertions(+), 48 deletions(-) create mode 100644 include/misc/cxl-base.h delete mode 100644 include/misc/cxl.h (limited to 'include/misc') diff --git a/include/misc/cxl-base.h b/include/misc/cxl-base.h new file mode 100644 index 000000000000..5ae962512fb8 --- /dev/null +++ b/include/misc/cxl-base.h @@ -0,0 +1,48 @@ +/* + * Copyright 2014 IBM Corp. + * + * This program is free software; you can redistribute it and/or + * modify it under the terms of the GNU General Public License + * as published by the Free Software Foundation; either version + * 2 of the License, or (at your option) any later version. + */ + +#ifndef _MISC_CXL_BASE_H +#define _MISC_CXL_BASE_H + +#ifdef CONFIG_CXL_BASE + +#define CXL_IRQ_RANGES 4 + +struct cxl_irq_ranges { + irq_hw_number_t offset[CXL_IRQ_RANGES]; + irq_hw_number_t range[CXL_IRQ_RANGES]; +}; + +extern atomic_t cxl_use_count; + +static inline bool cxl_ctx_in_use(void) +{ + return (atomic_read(&cxl_use_count) != 0); +} + +static inline void cxl_ctx_get(void) +{ + atomic_inc(&cxl_use_count); +} + +static inline void cxl_ctx_put(void) +{ + atomic_dec(&cxl_use_count); +} + +void cxl_slbia(struct mm_struct *mm); + +#else /* CONFIG_CXL_BASE */ + +static inline bool cxl_ctx_in_use(void) { return false; } +static inline void cxl_slbia(struct mm_struct *mm) {} + +#endif /* CONFIG_CXL_BASE */ + +#endif diff --git a/include/misc/cxl.h b/include/misc/cxl.h deleted file mode 100644 index 975cc7861f18..000000000000 --- a/include/misc/cxl.h +++ /dev/null @@ -1,48 +0,0 @@ -/* - * Copyright 2014 IBM Corp. - * - * This program is free software; you can redistribute it and/or - * modify it under the terms of the GNU General Public License - * as published by the Free Software Foundation; either version - * 2 of the License, or (at your option) any later version. - */ - -#ifndef _MISC_CXL_H -#define _MISC_CXL_H - -#ifdef CONFIG_CXL_BASE - -#define CXL_IRQ_RANGES 4 - -struct cxl_irq_ranges { - irq_hw_number_t offset[CXL_IRQ_RANGES]; - irq_hw_number_t range[CXL_IRQ_RANGES]; -}; - -extern atomic_t cxl_use_count; - -static inline bool cxl_ctx_in_use(void) -{ - return (atomic_read(&cxl_use_count) != 0); -} - -static inline void cxl_ctx_get(void) -{ - atomic_inc(&cxl_use_count); -} - -static inline void cxl_ctx_put(void) -{ - atomic_dec(&cxl_use_count); -} - -void cxl_slbia(struct mm_struct *mm); - -#else /* CONFIG_CXL_BASE */ - -static inline bool cxl_ctx_in_use(void) { return false; } -static inline void cxl_slbia(struct mm_struct *mm) {} - -#endif /* CONFIG_CXL_BASE */ - -#endif -- cgit v1.2.3-59-g8ed1b
