...("%s: size (zip %zd, unzip %zd) looks insane, skip gunzip\n", __FUNCTION__, ziplen, unziplen); return 0; } return unziplen + 16; } The returned unziplen+16 is used for the size of the destination buffer given to inflate. But it is then also written to the kernel_size attribute of the xc_dom_image struct. Hence kernel_size does not contain the uncompressed kernel size but that /plus/ 16. So why do you always add 16 bytes to the *real* uncompressed kernel size?? That doesn''t make much sense to me but I need to know it because it is related to my curr...

Hi, Line 762 of efi/main.c (git firmware branch) should be changed to if (hdr->version < 0x20b) { Without this change syslinux efi64 gives out "handover protocol unimplemented error" and fails to boot. With this change syslinux boots the kernels fine (tested with 3.6.9 and 3.7rc6 kernels). Please fix this. Thanks in advance. Regards. Keshav

Howdy, I know that syslinux doesn't currently support this, but does anyone here know how I might go about getting some sort of boot process together that would have a single firmware image as opposed to seperate files for initrd, kernel, and root fs? Thanks.

PXELINUX has stopped recognizing the keeppxe option on the kernel command line. Here is a patch to make it work again. With COM32, it is no longer possible to use preprocessor directives to determine the SYSLINUX variant. The code inside the #if will never be compiled. So, I changed it to use syslinux_filesystem() to determine the variant. Also, I moved the relevant code from

I''ve addressed all (I think/hope) of the review comments. The main change is to expose the guest virtual platform (e.g. memory layout and interrupt usage etc) to the toolstack via the public interface. This is then used during FDT generation. I have just codified the current defacto standard layout, it''s probably not the best layout but any change can be a separate patch/series.
