[lc-devel] Compressing a page using WKdm

[Anderson B. <bri...@gm...>]

Hi all,

I have been trying to compress a page using that WKdm code from
project's CVS. But, something is wrong because the system hangs after
some compression/decompression pages. I'm using this interface:

to compress "original_page":

int len;
len = WKdm_compress(page_address(original_page), page_address(comp_page), 1024);
memcpy(page_address(original_page), page_address(comp_page), len);

to decompress:

WKdm_decompress(page_address(original_page), page_address(decomp_page), 1024);
memcpy(page_address(original_page), page_address(decomp_page), PAGE_SIZE);

Is needed to do some padding? I saw at compress_test module that the
comp_data is filled with 0's after the compression. Is it necessary?

Best regards,
