 <p>Fortunately, you can create sysroots for foreign architectures with tools provided by your OS. On Debian/Ubuntu systems, one could use <code>qemu-deboostrap</code> to create the <em>target</em> system chroot, which would have the native libraries and headers specific to that <em>target</em> system. After that, we can use the cross-compiler on the <em>build</em> system, pointing into chroot to get the build dependencies right. This allows building for foreign architectures with native compilation speed.</p>

+### Common Test Groups
+
+Ideally, all tests are run for every change but this may not be practical due to the limited
+testing resources, the scope of the change, etc.
+
+The source tree currently defines a few common test groups in the relevant `TEST.groups`
+files. There are test groups that cover a specific component, for example `hotspot_gc`.
+It is a good idea to look into `TEST.groups` files to get a sense what tests are relevant
+to a particular JDK component.
+
+Component-specific tests may miss some unintended consequences of a change, so other
+tests should also be run. Again, it might be impractical to run all tests, and therefore
+_tiered_ test groups exist. Tiered test groups are not component-specific, but rather cover
+the significant parts of the entire JDK.
+
+Multiple tiers allow balancing test coverage and testing costs. Lower test tiers are supposed to
+contain the simpler, quicker and more stable tests. Higher tiers are supposed to contain
+progressively more thorough, slower, and sometimes less stable tests, or the tests that require
+special configuration.
+
+Contributors are expected to run the tests for the areas that are changed, and the first N tiers
+they can afford to run, but at least tier1.
+
+A brief description of the tiered test groups:
+
+- `tier1`: This is the lowest test tier. Multiple developers run these tests every day.
+Because of the widespread use, the tests in `tier1` are carefully selected and optimized to run
+fast, and to run in the most stable manner. The test failures in `tier1` are usually followed up
+on quickly, either with fixes, or adding relevant tests to problem list. GitHub Actions workflows,
+if enabled, run `tier1` tests.
+
+- `tier2`: This test group covers even more ground. These contain, among other things,
+tests that either run for too long to be at `tier1`, or may require special configuration,
+or tests that are less stable, or cover the broader range of non-core JVM and JDK features/components
+(for example, XML).
+
+- `tier3`: This test group includes more stressful tests, the tests for corner cases
+not covered by previous tiers, plus the tests that require GUIs. As such, this suite
