[V8,0/4] tests: Add migration test for aarch64

Message

Wei Huang Sept. 1, 2018, 5:11 a.m. UTC

This patchset adds a migration test for aarch64. It leverages
Dave Gilbert's migration boot block patches to create a new test case
for aarch64.

V7->V8:
 * Support cross compilation by searching for CROSS_CC_GUEST option,
   instead of using the find-cross-prefix defined in roms/Makefile
 * Use the "max" options for ARM guest VM's CPU and GIC types
 * $(TARGET)/Makefile rules are rewritten based on Laurent Vivier's comment
 * NOTE: because Patch 1/2 is re-written, I remove the "Reviewed-by" for
   reviewers to take a look again. Thanks.

V6->V7:
 * Define test memory start/end addresses for all architectures
 * Check aarch64 kernel binary size, limit under 512KB

V5->V6:
 * Add Reviewed-by to patch 1-3
 * Add more design notes in patch 4 (aarch64 assembly compilation, bin space)

V4->V5:
 * Extract cross compilation detection code into rules.mak for sharing
 * Minor comment and code revision in migration-test.c & aarch64-a-b-kernel.S
 
V3->V4:
 * Rename .s to .S, allowing assembly to include C-style header file
 * Move test defines into a new migration-test.h file
 * Use different cpu & gic settings for kvm and tcg modes on aarch64
 * Clean up aarch64-a-b-kernel.S based on Andrew Jones' comments
 
V2->V3:
 * Convert build script to Makefile
 * Add cross-compilation support
 * Fix CPU type for "tcg" machine type
 * Revise asm code and the compilation process from asm to header file

V1->V2:
 * Similar to Dave Gilbert's recent changes to migration-test, we
   provide the test source and a build script in V2.
 * aarch64 kernel blob is defined as "unsigned char" because the source
   is now provided in V2.
 * Add "-machine none" to test_deprecated() because aarch64 doesn't have
   a default machine type.

RFC->V1:
 * aarch64 kernel blob is defined as an uint32_t array
 * The test code is re-written to address a data caching issue under KVM.
   Tests passed under both x86 and aarch64.
 * Re-use init_bootfile_x86() for both x86 and aarch64
 * Other minor fixes

Thanks,
-Wei
