| * kvm: selftest: add dirty logging testPeter Xu2018-08-224-0/+356
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Test KVM dirty logging functionality. The test creates a standalone memory slot to test tracking the dirty pages since we can't really write to the default memory slot which still contains the guest ELF image. We have two threads running during the test: (1) the vcpu thread continuously dirties random guest pages by writting a iteration number to the first 8 bytes of the page (2) the host thread continuously fetches dirty logs for the testing memory region and verify each single bit of the dirty bitmap by checking against the values written onto the page Note that since the guest cannot calls the general userspace APIs like random(), it depends on the host to provide random numbers for the page indexes to dirty.

| * kvm: selftest: unify the guest port macrosPeter Xu2018-08-226-95/+78Star
| | | | | | | | | | | | | | | | | | | | | | | | | | Most of the tests are using the same way to do guest to host sync but the code is mostly duplicated. Generalize the guest port macros into the common header file and use it in different tests. Meanwhile provide "struct guest_args" and a helper "guest_args_read()" to hide the register details when playing with these port operations on RDI and RSI.

The commit adds tests for some core principles of croup V2 API: - test_cgcore_internal_process_constraint Tests internal process constraint. You can't add a pid to a domain parent if a controller is enabled. - test_cgcore_top_down_constraint_enable Tests that you can't enable a controller on a child if it's not enabled on the parent. - test_cgcore_top_down_constraint_disable Tests that you can't disable a controller on a parent if it's enabled in a child. - test_cgcore_no_internal_process_constraint_on_threads Tests that there's no internal process constrain on threaded cgroups. You can add threads/processes on a parent with a controller enabled. - test_cgcore_parent_becomes_threaded Tests that when a child becomes threaded the parent type becomes domain threaded. - test_cgcore_invalid_domain In a situation like: A (domain threaded) - B (threaded) - C (domain) it tests that C can't be used until it is turned into a threaded cgroup. The "cgroup.type" file will report "domain (invalid)" in these cases. Operations which fail due to invalid topology use EOPNOTSUPP as the errno. - test_cgcore_populated In a situation like: A(0) - B(0) - C(1) \ D(0) It tests that A, B and C's "populated" fields would be 1 while D's 0. It tests that after the one process in C is moved to root, A,B and C's "populated" fields would flip to "0" and file modified events will be generated on the "cgroup.events" files of both cgroups.

Joel Fernandes restructured the hooks from irqs and preemption disabling and enabling. He got rid of a lot of the preprocessor #ifdef mess that they caused. He turned both lockdep and the latency tracers to use trace events inserted in the preempt/irqs disabling paths. But unfortunately, these started to cause issues in corner cases. Thus, parts of the code was reverted back to where lockdep and the latency tracers just get called directly (without using the trace events). But because the original change cleaned up the code very nicely we kept that, as well as the trace events for preempt and irqs disabling, but they are limited to not being called in NMIs. - Have trace events use SRCU for "rcu idle" calls. This was required for the preempt/irqs off trace events. But it also had to not allow them to be called in NMI context. Waiting till Paul makes an NMI safe SRCU API. - New notrace SRCU API to allow trace events to use SRCU. - Addition of mcount-nop option support - SPDX headers replacing GPL templates. - Various other fixes and clean ups. - Some fixes are marked for stable, but were not fully tested before the merge window opened. * tag 'trace-v4.19' of git://git.kernel.org/pub/scm/linux/kernel/git/rostedt/linux-trace: (44 commits) tracing: Fix SPDX format headers to use C++ style comments tracing: Add SPDX License format tags to tracing files tracing: Add SPDX License format to bpf_trace.c blktrace: Add SPDX License format header s390/ftrace: Add -mfentry and -mnop-mcount support tracing: Add -mcount-nop option support tracing: Avoid calling cc-option -mrecord-mcount for every Makefile tracing: Handle CC_FLAGS_FTRACE more accurately Uprobe: Additional argument arch_uprobe to uprobe_write_opcode() Uprobes: Simplify uprobe_register() body tracepoints: Free early tracepoints after RCU is initialized uprobes: Use synchronize_rcu() not synchronize_sched() tracing: Fix synchronizing to event changes with tracepoint_synchronize_unregister() ftrace: Remove unused pointer ftrace_swapper_pid tracing: More reverting of "tracing: Centralize preemptirq tracepoints and unify their usage" tracing/irqsoff: Handle preempt_count for different configs tracing: Partial revert of "tracing: Centralize preemptirq tracepoints and unify their usage" tracing: irqsoff: Account for additional preempt_disable trace: Use rcu_dereference_raw for hooks from trace-event subsystem tracing/kprobes: Fix within_notrace_func() to check only notrace functions ...

The kvm_util API is expanded with two functions that manage the lifetime of a kvm_vm struct: the first closes the file descriptors and leaves the memory allocated, and the second opens the file descriptors and reuses the memory from the previous incarnation of the kvm_vm struct. For now the test is very basic, as it does not test for example XSAVE or vCPU events. However, it will test nested virtualization state starting with the next patch.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The selftests were not munmap-ing the kvm_run area from the vcpu file descriptor. The result was that kvm_vcpu_release was not called and a reference was left in the parent "struct kvm". Ultimately this was visible in the upcoming state save/restore test as an error when KVM attempted to create a duplicate debugfs entry. Signed-off-by: Paolo Bonzini <pbonzini@redhat.com>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The allocation of the VMXON and VMCS is currently done twice, in lib/vmx.c and in vmx_tsc_adjust_test.c. Reorganize the code to provide a cleaner and easier to use API to the tests. lib/vmx.c now does the complete setup of the VMX data structures, but does not create the VM or set CPUID. This has to be done by the caller. Signed-off-by: Paolo Bonzini <pbonzini@redhat.com>

Basically it worked by chance, and this patch fixes it by setting up all the protected mode data structures properly. Because the GDT and TSS addresses are virtual, the page tables now always exist at the time of vcpu setup. Signed-off-by: Paolo Bonzini <pbonzini@redhat.com>

However, it seems the detection of such cases is incomplete. It was found that with 'devicemapper' storage driver docker creates the following chain: NAME MAJ:MIN loop0 7:0 ..docker-8:4-8473394-pool 253:0 ..docker-8:4-8473394-eac... 253:1 so when we're looking at the mounted device we see major '253' and not '7'. Solve the issue by walking /sys/dev/block/*/slaves chain and checking if there's a loop device somewhere. Other than that, don't skip mountpoints silently when stat() fails. In case e.g. SELinux is failing stat we don't want to skip freezing everything without letting user know about the failure.

Core features * Channel types - New position relative channel type primarily for touch screen sensors to feed the generic touchscreen driver. New device support * ad5586 - Add support for the AD5311R DAC. * Generic touch screen driver as an IIO consumer. - Note this is in input, but due to dependencies is coming through the IIO tree. - Specific support for this added to the at91-sama5d2 ADC. - Various necessary DT bindings added. Staging Drops * ADIS16060 gyro - A device with a very odd interface that was never cleanly supported. It's now very difficult to get, so unlikely it'll ever be fixed up. Cleanups and minor features and fixes * core - Fix y2038 timestamp issues now the core support is in place. * 104-quad-8 - Provide some defines for magic numbers to help readability. - Fix an off by one error in register selection * ad7606 - Put in a missing function parameter name in a prototype. * adis16023 - Use generic sign_extend function rather than local version. * adis16240 - Use generic sign_extend funciton rather than local version. * at91-sama5d2 - Drop dependency on HAS_DMA now this is handled elsewhere. Will improve build test coverage. - Add oversampling ratio control. Note there is a minor ABI change here to increase the apparent depth to 14 bits so as to allow for transparent provision of different oversampling ratios that drop the actual bit depth to 13 or 12 bits. * hx711 - Add a MAINTAINERS entry for this device. * inv_mpu6050 - Replace the timestamp fifo 'special' code with generic timestamp handling. - Switch to using local store of timestamp divider rather than rate as that is more helpful for accurate time measurement. - Fix an unaligned access that didn't seem to be causing any trouble. - Use the fifo overflow bit to track the overflow status rather than a software counter. - New timestamping mechanism to deal with missed sample interrupts. * stm32-adc - Drop HAS_DMA build dependency. * sun4i-gpadc - Select REGMAP_IRQ a very rarely hit build issue fix.

These type of analog sensor offers the position of a pen on a touchpad, and is represented as a voltage, which can be converted to a position on X and Y axis on the pad. The channel will hand the relative position on the pad in both directions. The channel can then be consumed by a touchscreen driver or read as-is for a raw indication of the touchpen on a touchpad.

However, cpu_to_le16/32 are used when initializing structures, i.e in a context where a function call is not allowed. It works fine on little endian systems because htole16/32 are defined by the C library as no-ops. But on big-endian systems, they are actually doing something, which might involve calling a function, causing build failures, such as: ffs-test.c:48:25: error: initializer element is not constant #define cpu_to_le32(x) htole32(x) ^~~~~~~ ffs-test.c:128:12: note: in expansion of macro ‘cpu_to_le32’ .magic = cpu_to_le32(FUNCTIONFS_DESCRIPTORS_MAGIC_V2), ^~~~~~~~~~~ To solve this, we code cpu_to_le16/32 in a way that allows them to be used when initializing structures.
