From 7d81790ced345585b1e647ca9d0f6678e7062fa4 Mon Sep 17 00:00:00 2001 From: Dongsheng Yang Date: Sat, 31 Oct 2015 11:12:01 +0800 Subject: mtd-utils: Restructure the mtd-utils source. * There is no code modification in this commit, only moving * the files to proper place. The user tools looks a little messy as we place almost the all tools in the root directory of mtd-utils. To make it more clear, I propose to introduce the following structure for our source code. mtd-utils/ |-- lib |-- include |-- misc-utils |-- jffsX-utils |-- nand-utils |-- nor-utils |-- ubi-utils |-- ubifs-utils `-- tests Signed-off-by: Dongsheng Yang Signed-off-by: Brian Norris --- compr.h | 119 ---------------------------------------------------------------- 1 file changed, 119 deletions(-) delete mode 100644 compr.h (limited to 'compr.h') diff --git a/compr.h b/compr.h deleted file mode 100644 index a21e935..0000000 --- a/compr.h +++ /dev/null @@ -1,119 +0,0 @@ -/* - * JFFS2 -- Journalling Flash File System, Version 2. - * - * Copyright (C) 2004 Ferenc Havasi , - * University of Szeged, Hungary - * - * For licensing information, see the file 'LICENCE' in the - * jffs2 directory. - */ - -#ifndef __JFFS2_COMPR_H__ -#define __JFFS2_COMPR_H__ - -#include -#include -#include -#include "linux/jffs2.h" - -#define CONFIG_JFFS2_ZLIB -#define CONFIG_JFFS2_RTIME -#define CONFIG_JFFS2_LZO - -#define JFFS2_RUBINMIPS_PRIORITY 10 -#define JFFS2_DYNRUBIN_PRIORITY 20 -#define JFFS2_RTIME_PRIORITY 50 -#define JFFS2_ZLIB_PRIORITY 60 -#define JFFS2_LZO_PRIORITY 80 - -#define JFFS2_COMPR_MODE_NONE 0 -#define JFFS2_COMPR_MODE_PRIORITY 1 -#define JFFS2_COMPR_MODE_SIZE 2 -#define JFFS2_COMPR_MODE_FAVOURLZO 3 - -#define kmalloc(a,b) malloc(a) -#define kfree(a) free(a) -#ifndef GFP_KERNEL -#define GFP_KERNEL 0 -#endif - -#define vmalloc(a) malloc(a) -#define vfree(a) free(a) - -#define printk(...) fprintf(stderr,__VA_ARGS__) - -#define KERN_EMERG -#define KERN_ALERT -#define KERN_CRIT -#define KERN_ERR -#define KERN_WARNING -#define KERN_NOTICE -#define KERN_INFO -#define KERN_DEBUG - -struct list_head { - struct list_head *next, *prev; -}; - -void jffs2_set_compression_mode(int mode); -int jffs2_get_compression_mode(void); -int jffs2_set_compression_mode_name(const char *mode_name); - -int jffs2_enable_compressor_name(const char *name); -int jffs2_disable_compressor_name(const char *name); - -int jffs2_set_compressor_priority(const char *name, int priority); - -struct jffs2_compressor { - struct list_head list; - int priority; /* used by prirority comr. mode */ - const char *name; - char compr; /* JFFS2_COMPR_XXX */ - int (*compress)(unsigned char *data_in, unsigned char *cpage_out, - uint32_t *srclen, uint32_t *destlen); - int (*decompress)(unsigned char *cdata_in, unsigned char *data_out, - uint32_t cdatalen, uint32_t datalen); - int usecount; - int disabled; /* if seted the compressor won't compress */ - unsigned char *compr_buf; /* used by size compr. mode */ - uint32_t compr_buf_size; /* used by size compr. mode */ - uint32_t stat_compr_orig_size; - uint32_t stat_compr_new_size; - uint32_t stat_compr_blocks; - uint32_t stat_decompr_blocks; -}; - -int jffs2_register_compressor(struct jffs2_compressor *comp); -int jffs2_unregister_compressor(struct jffs2_compressor *comp); - -int jffs2_compressors_init(void); -int jffs2_compressors_exit(void); - -uint16_t jffs2_compress(unsigned char *data_in, unsigned char **cpage_out, - uint32_t *datalen, uint32_t *cdatalen); - -/* If it is setted, a decompress will be called after every compress */ -void jffs2_compression_check_set(int yesno); -int jffs2_compression_check_get(void); -int jffs2_compression_check_errorcnt_get(void); - -char *jffs2_list_compressors(void); -char *jffs2_stats(void); - -/* Compressor modules */ - -/* These functions will be called by jffs2_compressors_init/exit */ -#ifdef CONFIG_JFFS2_ZLIB -int jffs2_zlib_init(void); -void jffs2_zlib_exit(void); -#endif -#ifdef CONFIG_JFFS2_RTIME -int jffs2_rtime_init(void); -void jffs2_rtime_exit(void); -#endif -#ifdef CONFIG_JFFS2_LZO -int jffs2_lzo_init(void); -void jffs2_lzo_exit(void); -#endif - -#endif /* __JFFS2_COMPR_H__ */ -- cgit v1.2.3
