tests/migration: Support cross compilation in generating boot header file Recently a new configure option, CROSS_CC_GUEST, was added to $(TARGET)-softmmu/config-target.mak to support TCG-related tests. This patch tries to leverage this option to support cross compilation when the migration boot block file is being re-generated: * The x86 related files are moved to a new sub-dir (named ./i386). * A new top-layer Makefile is created in tests/migration/ directory. This Makefile searches and parses CROSS_CC_GUEST to generate CROSS_PREFIX. The CROSS_PREFIX, if available, is then passed to migration/$ARCH/Makefile.

tests/migration: Add source to PC boot block The boot block used in the migration test is currently only shipped as a hex (with the source in the git commit message of ea0c6d62), change this to actually include the source. A script is added to rebuild the header but the expectation is that the generated hex is shipped as well as the .s, so that there's no requirement to have just the right assembler etc. Signed-off-by: Dr. David Alan Gilbert <dgilbert@redhat.com> Message-Id: <20180213100606.5379-1-dgilbert@redhat.com> Reviewed-by: Eric Blake <eblake@redhat.com> Signed-off-by: Dr. David Alan Gilbert <dgilbert@redhat.com> Removed blank line at end of script

tests/qtest: option to suspend during migration Add an option to suspend the src in a-b-bootblock.S, which puts the guest in S3 state after one round of writing to memory. The option is enabled by poking a 1 into the suspend_me word in the boot block prior to starting the src vm. Generate symbol offsets in a-b-bootblock.h so that the suspend_me offset is known. Generate the bootblock for each test, because suspend_me may differ for each.

i386/a-b-bootblock: zero the first byte of each page on start The migration qtest all the way up to this point used to work by sheer luck relying on the contents of all pages from 1MiB to 100MiB to contain the same one value in the first byte initially. This easily breaks if we reduce the amount of RAM for the test instances from 150MiB to e.g 110MiB since that makes SeaBIOS dirty some of the pages starting at about 0x5dd2000 (~93 MiB) as it reuses those for the HighMemory allocator since commit dc88f9b72df ("malloc: use large ZoneHigh when there is enough memory"). This would result in the following errors: 12/60 qemu:qtest+qtest-x86_64 / qtest-x86_64/migration-test ERROR 2.74s killed by signal 6 SIGABRT stderr: Memory content inconsistency at 5dd2000 first_byte = cc last_byte = cb current = 9e hit_edge = 1 Memory content inconsistency at 5dd3000 first_byte = cc last_byte = cb current = 89 hit_edge = 1 Memory content inconsistency at 5dd4000 first_byte = cc last_byte = cb current = 23 hit_edge = 1 Memory content inconsistency at 5dd5000 first_byte = cc last_byte = cb current = 31 hit_edge = 1 Memory content inconsistency at 5dd6000 first_byte = cc last_byte = cb current = 70 hit_edge = 1 Memory content inconsistency at 5dd7000 first_byte = cc last_byte = cb current = ff hit_edge = 1 Memory content inconsistency at 5dd8000 first_byte = cc last_byte = cb current = 54 hit_edge = 1 Memory content inconsistency at 5dd9000 first_byte = cc last_byte = cb current = 64 hit_edge = 1 Memory content inconsistency at 5dda000 first_byte = cc last_byte = cb current = 1d hit_edge = 1 Memory content inconsistency at 5ddb000 first_byte = cc last_byte = cb current = 1a hit_edge = 1 and in another 26 pages** ERROR:../tests/qtest/migration-test.c:300:check_guests_ram: assertion failed: (bad == 0) Fix this by always zeroing the first byte of each page in the range so that we get consistent results no matter the initial contents.
