[RFC] Adding support for dynamic entries in yaml2obj
...amic entry strings that belong in .dynstr, the string itself can be used as the value for an entry. (ex. DT_SONAME, DT_NEEDED, DT_RPATH, and DT_RUNPATH) 2. A section name can be used in place of an address. In this case, the value of the dynamic entry is the sh_addr of the specified section. (ex. DT_STRTAB, DT_SYMTAB, DT_HASH, DT_RELA, and others) 3. A value can be specified using hexadecimal or decimal (or other bases supported by `StringRef::to_integer()`). (ex. DT_STRSZ, DT_SYMENT, DT_RELAENT, and others) Here's an example to illustrate this design: !ELF FileHeader: Class: E...

[RFC, PATCH 7/24] i386 Vmi memory hole
Create a configurable hole in the linear address space at the top of memory. A more advanced interface is needed to negotiate how much space the hypervisor is allowed to steal, but in the end, it seems most likely that a fixed constant size will be chosen for the compiled kernel, potentially propagated to an information page used by paravirtual initialization to determine interface compatibility.

[patch 0/2] Updates to compat VDSOs
Hi Andi, Here's a couple of patches to fix up COMPAT_VDSO: The first is a straightforward implementation of Jan's original idea of relocating the VDSO to match its mapped location. Unlike Jan and Zach's version, I changed it to relocate based on the phdrs rather than the sections; the result is pleasantly compact. The second patch takes advantage of the fact that all the

[patch 0/4] Clean up asm/bugs.h, identify_cpu() and update COMPAT_VDSO
Hi Andi, Four patches: - clean up asm/bugs.h, by moving all the C code into its own C file - split identify_cpu() into boot and secondary variants, so that boot-time setup functions can be marked __init - repost of the COMPAT_VDSO patches with a bit more robustness from unknown DT_tags, and functions marked __init, since all this is boot-time only setup. Thanks, J --
