- CONFIG_LZMA - - If this option is set, support for lzma compressed - images is included. - - Note: The LZMA algorithm adds between 2 and 4KB of code and it - requires an amount of dynamic memory that is given by the - formula: - - (1846 + 768 << (lc + lp)) * sizeof(uint16) - - Where lc and lp stand for, respectively, Literal context bits - and Literal pos bits. - - This value is upper-bounded by 14MB in the worst case. Anyway, - for a ~4MB large kernel image, we have lc=3 and lp=0 for a - total amount of (1846 + 768 << (3 + 0)) * 2 = ~41KB... that is - a very small buffer. - - Use the lzmainfo tool to determinate the lc and lp values and - then calculate the amount of needed dynamic memory (ensuring - the appropriate CONFIG_SYS_MALLOC_LEN value). - CONFIG_LZO
