x86/xen: add some __init and static annotations in arch/x86/xen/setup.c

2015-01-28T10:00:36+00:00

Some more functions in arch/x86/xen/setup.c can be made "__init". xen_ignore_unusable() can be made "static". Signed-off-by: Juergen Gross Signed-off-by: David Vrabel

x86/xen: use correct types for addresses in arch/x86/xen/setup.c

2015-01-28T10:00:10+00:00

In many places in arch/x86/xen/setup.c wrong types are used for physical addresses (u64 or unsigned long long). Use phys_addr_t instead. Use macros already defined instead of open coding them. Correct some other type mismatches. Signed-off-by: Juergen Gross Signed-off-by: David Vrabel

x86/xen: cleanup arch/x86/xen/setup.c

2015-01-28T09:59:46+00:00

Remove extern declarations in arch/x86/xen/setup.c which are either not used or redundant. Move needed other extern declarations to xen-ops.h Signed-off-by: Juergen Gross Signed-off-by: David Vrabel

xen: check for zero sized area when invalidating memory

2015-01-12T10:09:55+00:00

With the introduction of the linear mapped p2m list setting memory areas to "invalid" had to be delayed. When doing the invalidation make sure no zero sized areas are processed. Signed-off-by: Juegren Gross Signed-off-by: David Vrabel

xen: use correct type for physical addresses

2015-01-12T10:09:48+00:00

When converting a pfn to a physical address be sure to use 64 bit wide types or convert the physical address to a pfn if possible. Signed-off-by: Juergen Gross Tested-by: Boris Ostrovsky Signed-off-by: David Vrabel

x86/xen: add extra memory for remapped frames during setup

2015-01-08T13:52:37+00:00

If the non-RAM regions in the e820 memory map are larger than the size of the initial balloon, a BUG was triggered as the frames are remaped beyond the limit of the linear p2m. The frames are remapped into the initial balloon area (xen_extra_mem) but not enough of this is available. Ensure enough extra memory regions are added for these remapped frames.

x86/xen: don't count how many PFNs are identity mapped

2015-01-08T13:52:36+00:00

This accounting is just used to print a diagnostic message that isn't very useful. Signed-off-by: David Vrabel Reviewed-by: Juergen Gross

xen: annotate xen_set_identity_and_remap_chunk() with __init

2014-12-08T10:55:30+00:00

Commit 5b8e7d80542487ff1bf17b4cf2922a01dee13d3a removed the __init annotation from xen_set_identity_and_remap_chunk(). Add it again. Signed-off-by: Juergen Gross Signed-off-by: David Vrabel

xen: Delay invalidating extra memory

2014-12-04T14:08:59+00:00

When the physical memory configuration is initialized the p2m entries for not pouplated memory pages are set to "invalid". As those pages are beyond the hypervisor built p2m list the p2m tree has to be extended. This patch delays processing the extra memory related p2m entries during the boot process until some more basic memory management functions are callable. This removes the need to create new p2m entries until virtual memory management is available. Signed-off-by: Juergen Gross Reviewed-by: David Vrabel Signed-off-by: David Vrabel

xen: Delay remapping memory of pv-domain

2014-12-04T14:08:48+00:00

Early in the boot process the memory layout of a pv-domain is changed to match the E820 map (either the host one for Dom0 or the Xen one) regarding placement of RAM and PCI holes. This requires removing memory pages initially located at positions not suitable for RAM and adding them later at higher addresses where no restrictions apply. To be able to operate on the hypervisor supported p2m list until a virtual mapped linear p2m list can be constructed, remapping must be delayed until virtual memory management is initialized, as the initial p2m list can't be extended unlimited at physical memory initialization time due to it's fixed structure. A further advantage is the reduction in complexity and code volume as we don't have to be careful regarding memory restrictions during p2m updates.
