MemMapEntries initialized in this array have a static size and base address. - extended_memmap, only initialized with entries located after the RAM. MemMapEntries initialized in this array only get their size initialized. Their base address is dynamically computed depending on the the top of the RAM, with same alignment as their size. Eventually base_memmap entries are copied into the extended_memmap array. Using two separate arrays however clarifies which entries are statically allocated and those which are dynamically allocated. This new split will allow to grow the RAM size without changing the description of the high IO entries. We introduce a new virt_set_memmap() helper function which "freezes" the memory map. The memory map is unchanged (the top of the initial RAM still is 256GiB). Then come the high IO regions with same layout as before. Signed-off-by: Eric Auger --- v7 -> v8: - removed Peter's R-b due to the changes induced by Igor's comments - call set_memmap back in virt_instance_init - add comments about sizing of extended_memmap - s/region/entries as suggested by Igor - rewording of the commit message v6 -> v7: - s/a15memmap/base_memmap - slight rewording of the commit message - add "if there is less than 256GiB of RAM then the floating area starts at the 256GiB mark" in the comment associated to the floating memory map - Added Peter's R-b v5 -> v6 - removal of many macros in units.h - introduce the virt_set_memmap helper - new computation for offsets of high IO regions - add comments --- hw/arm/virt.c | 51 ++++++++++++++++++++++++++++++++++++++----- include/hw/arm/virt.h | 14 ++++++++---- 2 files changed, 55 insertions(+), 10 deletions(-) diff --git a/hw/arm/virt.c b/hw/arm/virt.c index 892bae4f3a..7297b69d93 100644 --- a/hw/arm/virt.c +++ b/hw/arm/virt.c @@ -29,6 +29,7 @@ */ #include "qemu/osdep.h" +#include "qemu/units.h" #include "qapi/error.h" #include "hw/sysbus.h" #include "hw/arm/arm.h" @@ -121,7 +122,7 @@ * Note that devices should generally be placed at multiples of 0x10000, * to accommodate guests using 64K pages. */ -static const MemMapEntry a15memmap[] = { +static const MemMapEntry base_memmap[] = { /* Space up to 0x8000000 is reserved for a boot ROM */ [VIRT_FLASH] = { 0, 0x08000000 }, [VIRT_CPUPERIPHS] = { 0x08000000, 0x00020000 }, @@ -149,11 +150,24 @@ static const MemMapEntry a15memmap[] = { [VIRT_PCIE_PIO] = { 0x3eff0000, 0x00010000 }, [VIRT_PCIE_ECAM] = { 0x3f000000, 0x01000000 }, [VIRT_MEM] = { 0x40000000, RAMLIMIT_BYTES }, +}; + +/* + * Highmem IO Regions: This memory map is floating, located after the RAM. + * Each MemMapEntry base (GPA) will be dynamically computed, depending on the + * top of the RAM, so that its base get the same alignment as the size, + * ie. a 512GiB entry will be aligned on a 512GiB boundary.

This patch modifies the virt_set_memmap() function, which freezes the memory map, so that the high IO range base becomes floating, located after the initial RAM and the device memory. The function computes - the base of the device memory, - the size of the device memory, - the high IO region base - the highest GPA used in the memory map. Entries of the high IO region are assigned a base address. The device memory is initialized. The highest GPA used in the memory map will be used at VM creation to choose the requested IPA size. Setting all the existing highmem IO regions beyond the RAM allows to have a single contiguous RAM region (initial RAM and possible hotpluggable device memory). That way we do not need to do invasive changes in the EDK2 FW to support a dynamic RAM base. Still the user cannot request an initial RAM size greater than 255GB.

The returned value in passed though the KVM_CREATE_VM ioctl and this allows KVM to set the stage2 tables dynamically.
