2024-06-14tests/qtest/migration-test: Use custom asm bios for ppc64Nicholas Piggin5-1/+125
Similar to other archs, build a custom bios memory updater. Running the test with OF code is a cool trick, but SLOF takes a long time to boot. This reduces test time by around 3x (150s to 50s).

2024-01-04tests/qtest: option to suspend during migrationSteve Sistare3-13/+68
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.

Use a shorter name. We are going to move in iotests from qmp() to command() where possible. But command() is longer than qmp() and don't look better. Let's rename. You can simply grep for '\.command(' and for 'def command(' to check that everything is updated (command() in tests/docker/docker.py is unrelated).

2023-10-04i386/a-b-bootblock: zero the first byte of each page on startDaniil Tatianin2-8/+17
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.

2022-08-24tests/migration/aarch64: Speed up the aarch64 migration testThomas Huth2-7/+6
The migration tests spend a lot of time waiting for a sign of live of the guest on the serial console. The aarch64 migration code only outputs "B"s every couple of seconds (at least it takes more than 4 seconds between each characeter on my x86 laptop). There are a lot of migration tests, and if each test that checks for a successful migration waits for these characters before and after migration, the wait time sums up to multiple minutes! Let's use a shorter delay to speed things up. While we're at it, also remove a superfluous masking with 0xff - we're reading and storing bytes, so the upper bits of the register do not matter anyway. With these changes, the test runs twice as fast on my laptop, decreasing the total run time from approx. 8 minutes to only 4 minutes!

The reason is that batch script use the same monitor socket in all test cases and do not remove the socket file. The second migration test will launch vm use the same socket file as the first, so we get the error message. To fix it, just remove the socket file each time we have done the migration test.

2018-10-11migration-test: Only generate a single target architectureJuan Quintela1-9/+14
Several changes: - We only allow generate header "inside" the tree. Why? Because we need to connit the result, so it makes no sense to generate them on the build dir. - We only generate a single target each time. Getting all the cross-compilers correctly is an impossible task. So know you do: make -C tests/migration $target (native) make CROSS_PREFIX=foo- -C tests/migratiion $target (cross) And you are done. - If we are building out of tree, we have no data about if we are cross-compile or whatever. So instead of guess what is happening, just do what I pointed on previous point.

2018-10-11tests: Add migration test for aarch64Wei Huang5-1/+121
This patch adds migration test support for aarch64. The test code, which implements the same functionality as x86, is booted as a kernel in qemu. Here are the design choices we make for aarch64: * We choose this -kernel approach because aarch64 QEMU doesn't provide a built-in fw like x86 does. So instead of relying on a boot loader, we use -kernel approach for aarch64. * The serial output is sent to PL011 directly. * The physical memory base for mach-virt machine is 0x40000000. We change the start_address and end_address for aarch64. In addition to providing the binary, this patch also includes the source code and the build script in tests/migration/aarch64. So users can change the source and/or re-compile the binary as they wish.
