mtd-utils: Add flash_otp_erase

2021-06-12T15:16:33+00:00

On some SPI NOR flashes you can actually erase the OTP region until its fully locked. Add a small utility for that. Signed-off-by: Michael Walle Signed-off-by: David Oberhollenzer

mtd-utils: flash_erase: Add flash erase chip

2021-05-05T06:29:50+00:00

Some flash types support full erase chip command which can reduce the flash erase time. Try first to erase the entire flash and fall back to the old method if the operation fails. Signed-off-by: Larisa Ileana Grigore Signed-off-by: David Oberhollenzer

mtd-utils: Use AC_SYS_LARGEFILE

2021-02-28T12:36:26+00:00

Currently mtd-utils on 32bit systems fail on devices >2GiB due to off_t being a signed 32bit type. Add AC_SYS_LARGEFILE to make off_t a 64bit type. Adding AC_SYS_LARGEFILE results in _FILE_OFFSET_BITS being defined to 64 in include/config.h. To let this have an effect we must make sure that include/config.h is included before all other includes which is archieved by adding its inclusion to CPPFLAGS.

libubi: remove private kernel header from includes

2020-01-30T10:23:02+00:00

libubi.h includes ubi-media.h which was made private in the kernel a long time ago. There are users of libubi.h, e.g. swupdate, which have to have ubi-media.h available at build time with this inclusion. However, libubi.h uses only one symbol from ubi-media.h. Define that symbol in the header to enable using libubi.h without installing ubi-media.h. Make up for the transitive symbol use in ubiformat.c by including ubi-media.h.

libubigen: remove unnecessary include

2020-01-30T10:23:02+00:00

libubigen.h does not use any symbol from mtd/ubi-media.h, so remove it from includes. Signed-off-by: Bastian Germann Signed-off-by: David Oberhollenzer

ubifs-media: Update to Linux-5.3-rc3

2019-08-19T07:26:58+00:00

This updates ubifs-media.h to Linux-5.3-rc3 which brings us the bits and pieces necessary for UBIFS authentication and offline signing. Signed-off-by: Sascha Hauer Signed-off-by: David Oberhollenzer

mkfs.ubifs: Add ZSTD compression

2019-06-01T17:38:44+00:00

I added ZSTD support to mkfs.ubifs and compared the ZSTD results with zlib/lzo and the available ZSTD compression levels. The results are in the following table: Comp image MiB time image2 MiB time none 271 0m 0,723s 223 0m 0,589s lzo 164 0m13,705s 116 0m11,636s zlib 150 0m 7,654s 103 0m 6,347s favor-lzo 158 0m21,137s 110 0m17,764s zstd-01 154 0m 1,607s 106 0m 1,429s zstd-02 153 0m 1,704s 105 0m 1,479s zstd-03* 152 0m 1,888s 104 0m 1,668s zstd-04 151 0m 2,741s 103 0m 2,391s zstd-05 150 0m 3,257s 102 0m 2,916s zstd-06 150 0m 3,735s 102 0m 3,356s zstd-07 150 0m 4,066s 102 0m 3,705s zstd-08 152 0m 1,857s 104 0m 1,644s zstd-09 152 0m 1,855s 104 0m 1,639s zstd-10 150 0m 6,654s 102 0m 6,195s zstd-11 150 0m10,027s 102 0m 9,130s zstd-12 149 0m14,724s 101 0m13,415s zstd-13 148 0m18,232s 100 0m16,719s zstd-14 148 0m20,859s 100 0m19,554s zstd-15 148 0m25,033s 100 0m23,186s zstd-16 148 0m38,837s 100 0m36,543s zstd-17 148 0m46,051s 100 0m43,120s zstd-18 148 0m49,157s 100 0m45,807s zstd-19 148 0m49,421s 100 0m45,951s zstd-20 148 0m51,271s 100 0m48,030s zstd-21 148 0m51,015s 100 0m48,676s zstd-22 148 0m52,575s 100 0m50,013s The UBIFS image was created via mkfs.ubifs -x $Comp -m 512 -e 128KiB -c 2200 -r $image $out I used "debootstrap sid" to create a basic RFS and the results are in the `image' column. The image2 column denotes the results for the same image but with .deb files removed. The time column contains the output of the run time of the command. ZSTD's compression level three is currently default. Based on the compression results (for the default level) it outperforms LZO in run time and compression and is almost as good as ZLIB in terms of compression but quicker. The higher compression levels make almost no difference in compression but take a lot of time. The compression level used is the default offered by ZSTD. It does not make sense the higher levels.
