Coverage collection
-------------------
+
The following program demonstrates coverage collection from within a test
program using kcov:
Comparison operands collection
------------------------------
+
Comparison operands collection is similar to coverage collection:
.. code-block:: c
Note that the kcov modes (coverage collection or comparison operands) are
mutually exclusive.
+
+Remote coverage collection
+--------------------------
+
+With KCOV_ENABLE coverage is collected only for syscalls that are issued
+from the current process. With KCOV_REMOTE_ENABLE it's possible to collect
+coverage for arbitrary parts of the kernel code, provided that those parts
+are annotated with kcov_remote_start()/kcov_remote_stop().
+
+This allows to collect coverage from two types of kernel background
+threads: the global ones, that are spawned during kernel boot in a limited
+number of instances (e.g. one USB hub_event() worker thread is spawned per
+USB HCD); and the local ones, that are spawned when a user interacts with
+some kernel interface (e.g. vhost workers).
+
+To enable collecting coverage from a global background thread, a unique
+global handle must be assigned and passed to the corresponding
+kcov_remote_start() call. Then a userspace process can pass a list of such
+handles to the KCOV_REMOTE_ENABLE ioctl in the handles array field of the
+kcov_remote_arg struct. This will attach the used kcov device to the code
+sections, that are referenced by those handles.
+
+Since there might be many local background threads spawned from different
+userspace processes, we can't use a single global handle per annotation.
+Instead, the userspace process passes a non-zero handle through the
+common_handle field of the kcov_remote_arg struct. This common handle gets
+saved to the kcov_handle field in the current task_struct and needs to be
+passed to the newly spawned threads via custom annotations. Those threads
+should in turn be annotated with kcov_remote_start()/kcov_remote_stop().
+
+Internally kcov stores handles as u64 integers. The top byte of a handle
+is used to denote the id of a subsystem that this handle belongs to, and
+the lower 4 bytes are used to denote the id of a thread instance within
+that subsystem. A reserved value 0 is used as a subsystem id for common
+handles as they don't belong to a particular subsystem. The bytes 4-7 are
+currently reserved and must be zero. In the future the number of bytes
+used for the subsystem or handle ids might be increased.
+
+When a particular userspace proccess collects coverage by via a common
+handle, kcov will collect coverage for each code section that is annotated
+to use the common handle obtained as kcov_handle from the current
+task_struct. However non common handles allow to collect coverage
+selectively from different subsystems.

+kunit_tool How-To
+=================
+
+What is kunit_tool?
+===================
+
+kunit_tool is a script (``tools/testing/kunit/kunit.py``) that aids in building
+the Linux kernel as UML (`User Mode Linux
+<http://user-mode-linux.sourceforge.net/>`_), running KUnit tests, parsing
+the test results and displaying them in a user friendly manner.
+
+What is a kunitconfig?
+======================
+
+It's just a defconfig that kunit_tool looks for in the base directory.
+kunit_tool uses it to generate a .config as you might expect. In addition, it
+verifies that the generated .config contains the CONFIG options in the
+kunitconfig; the reason it does this is so that it is easy to be sure that a
+CONFIG that enables a test actually ends up in the .config.
+
+How do I use kunit_tool?
+========================
+
+If a kunitconfig is present at the root directory, all you have to do is:
+
+.. code-block:: bash
+
+ ./tools/testing/kunit/kunit.py run
+
+However, you most likely want to use it with the following options:
+
+.. code-block:: bash
+
+ ./tools/testing/kunit/kunit.py run --timeout=30 --jobs=`nproc --all`
+
+- ``--timeout`` sets a maximum amount of time to allow tests to run.
+- ``--jobs`` sets the number of threads to use to build the kernel.
+
+If you just want to use the defconfig that ships with the kernel, you can
+append the ``--defconfig`` flag as well:
+
+.. code-block:: bash
+
+ ./tools/testing/kunit/kunit.py run --timeout=30 --jobs=`nproc --all` --defconfig
+
+.. note::
+ This command is particularly helpful for getting started because it
+ just works. No kunitconfig needs to be present.
+
+For a list of all the flags supported by kunit_tool, you can run:
+
+.. code-block:: bash
+
+ ./tools/testing/kunit/kunit.py run --help
.. code-block:: bash
- ./tools/testing/kunit/kunit.py run
+ ./tools/testing/kunit/kunit.py run --defconfig
+
+For more information on this wrapper (also called kunit_tool) checkout the
+:doc:`kunit-tool` page.

By default KUnit uses UML as a way to provide dependencies for code under test.

implementation detail of how KUnit works under the hood. Nevertheless, there

-== Introduction==
-
-LLCC (Last Level Cache Controller) provides last level of cache memory in SOC,
-that can be shared by multiple clients. Clients here are different cores in the
-SOC, the idea is to minimize the local caches at the clients and migrate to
-common pool of memory. Cache memory is divided into partitions called slices
-which are assigned to clients. Clients can query the slice details, activate
-and deactivate them.
-
-Properties:
-- compatible:
- Usage: required
- Value type: <string>
- Definition: must be "qcom,sdm845-llcc"
-
-- reg:
- Usage: required
- Value Type: <prop-encoded-array>
- Definition: The first element specifies the llcc base start address and
- the size of the register region. The second element specifies
- the llcc broadcast base address and size of the register region.
-
-- reg-names:
- Usage: required
- Value Type: <stringlist>
- Definition: Register region names. Must be "llcc_base", "llcc_broadcast_base".
-
-- interrupts:
- Usage: required
- Definition: The interrupt is associated with the llcc edac device.
- It's used for llcc cache single and double bit error detection
- and reporting.
-
-Example:
-
- cache-controller@1100000 {
- compatible = "qcom,sdm845-llcc";
- reg = <0x1100000 0x200000>, <0x1300000 0x50000> ;
- reg-names = "llcc_base", "llcc_broadcast_base";

+* Exynos5422 frequency and voltage scaling for Dynamic Memory Controller device
+
+The Samsung Exynos5422 SoC has DMC (Dynamic Memory Controller) to which the DRAM
+memory chips are connected. The driver is to monitor the controller in runtime
+and switch frequency and voltage. To monitor the usage of the controller in
+runtime, the driver uses the PPMU (Platform Performance Monitoring Unit), which
+is able to measure the current load of the memory.
+When 'userspace' governor is used for the driver, an application is able to
+switch the DMC and memory frequency.
+
+Required properties for DMC device for Exynos5422:
+- compatible: Should be "samsung,exynos5422-dmc".
+- clocks : list of clock specifiers, must contain an entry for each
+ required entry in clock-names for CLK_FOUT_SPLL, CLK_MOUT_SCLK_SPLL,
+ CLK_FF_DOUT_SPLL2, CLK_FOUT_BPLL, CLK_MOUT_BPLL, CLK_SCLK_BPLL,
+ CLK_MOUT_MX_MSPLL_CCORE, CLK_MOUT_MX_MSPLL_CCORE_PHY, CLK_MOUT_MCLK_CDREX,
+- clock-names : should include "fout_spll", "mout_sclk_spll", "ff_dout_spll2",
+ "fout_bpll", "mout_bpll", "sclk_bpll", "mout_mx_mspll_ccore",
+ "mout_mclk_cdrex" entries
+- devfreq-events : phandles for PPMU devices connected to this DMC.
+- vdd-supply : phandle for voltage regulator which is connected.
+- reg : registers of two CDREX controllers.
+- operating-points-v2 : phandle for OPPs described in v2 definition.
+- device-handle : phandle of the connected DRAM memory device. For more
+ information please refer to documentation file:
+ Documentation/devicetree/bindings/ddr/lpddr3.txt
+- devfreq-events : phandles of the PPMU events used by the controller.
+- samsung,syscon-clk : phandle of the clock register set used by the controller,
+ these registers are used for enabling a 'pause' feature and are not
+ exposed by clock framework but they must be used in a safe way.
+ The register offsets are in the driver code and specyfic for this SoC
+ type.
+
+Optional properties for DMC device for Exynos5422:
+- interrupt-parent : The parent interrupt controller.
+- interrupts : Contains the IRQ line numbers for the DMC internal performance
+ event counters in DREX0 and DREX1 channels. Align with specification of the
+ interrupt line(s) in the interrupt-parent controller.
+- interrupt-names : IRQ names "drex_0" and "drex_1", the order should be the
+ same as in the 'interrupts' list above.

+ The EMC interfaces with the off-chip SDRAM to service the request stream
+ sent from Memory Controller. The EMC also has various performance-affecting
+ settings beyond the obvious SDRAM configuration parameters and initialization
+ settings. Tegra30 EMC supports multiple JEDEC standard protocols: LPDDR2,
+ LPDDR3, and DDR3.

+description: |
+ Tegra30 Memory Controller architecturally consists of the following parts:
+
+ Arbitration Domains, which can handle a single request or response per
+ clock from a group of clients. Typically, a system has a single Arbitration
+ Domain, but an implementation may divide the client space into multiple
+ Arbitration Domains to increase the effective system bandwidth.
+
+ Protocol Arbiter, which manage a related pool of memory devices. A system
+ may have a single Protocol Arbiter or multiple Protocol Arbiters.
+
+ Memory Crossbar, which routes request and responses between Arbitration
+ Domains and Protocol Arbiters. In the simplest version of the system, the
+ Memory Crossbar is just a pass through between a single Arbitration Domain
+ and a single Protocol Arbiter.
+
+ Global Resources, which include things like configuration registers which
+ are shared across the Memory Subsystem.
+
+ The Tegra30 Memory Controller handles memory requests from internal clients
+ and arbitrates among them to allocate memory bandwidth for DDR3L and LPDDR2
+ SDRAMs.

+NVIDIA Tegra Regulators Coupling
+================================
+
+NVIDIA Tegra SoC's have a mandatory voltage-coupling between regulators.
+Thus on Tegra20 there are 3 coupled regulators and on NVIDIA Tegra30
+there are 2.
+
+Tegra20 voltage coupling
+------------------------
+
+On Tegra20 SoC's there are 3 coupled regulators: CORE, RTC and CPU.
+The CORE and RTC voltages shall be in a range of 170mV from each other
+and they both shall be higher than the CPU voltage by at least 120mV.
+
+Tegra30 voltage coupling
+------------------------
+
+On Tegra30 SoC's there are 2 coupled regulators: CORE and CPU. The CORE
+and CPU voltages shall be in a range of 300mV from each other and CORE
+voltage shall be higher than the CPU by N mV, where N depends on the CPU
+voltage.
+
+Required properties:
+- nvidia,tegra-core-regulator: Boolean property that designates regulator
+ as the "Core domain" voltage regulator.
+- nvidia,tegra-rtc-regulator: Boolean property that designates regulator
+ as the "RTC domain" voltage regulator.
+- nvidia,tegra-cpu-regulator: Boolean property that designates regulator
+ as the "CPU domain" voltage regulator.
+
+Example:
+
+ pmic {
+ regulators {
+ core_vdd_reg: core {
+ regulator-name = "vdd_core";
+ regulator-min-microvolt = <950000>;
+ regulator-max-microvolt = <1300000>;
+ regulator-coupled-with = <&rtc_vdd_reg &cpu_vdd_reg>;
+ regulator-coupled-max-spread = <170000 550000>;
+
+ nvidia,tegra-core-regulator;
+ };
+
+ rtc_vdd_reg: rtc {
+ regulator-name = "vdd_rtc";
+ regulator-min-microvolt = <950000>;
+ regulator-max-microvolt = <1300000>;
+ regulator-coupled-with = <&core_vdd_reg &cpu_vdd_reg>;

- Must be one of the following:
- - "qcom,msm8916-tsens" (MSM8916)
- - "qcom,msm8974-tsens" (MSM8974)
- - "qcom,msm8996-tsens" (MSM8996)

- - "qcom,sdm845-tsens", "qcom,tsens-v2" (SDM845)
- The generic "qcom,tsens-v2" property must be used as a fallback for any SoC
- with version 2 of the TSENS IP. MSM8996 is the only exception because the
- generic property did not exist when support was added.
- Similarly, the generic "qcom,tsens-v1" property must be used as a fallback for
- any SoC with version 1 of the TSENS IP.
-
-- reg: Address range of the thermal registers.
- New platforms containing v2.x.y of the TSENS IP must specify the SROT and TM
- register spaces separately, with order being TM before SROT.
- See Example 2, below.
-
-- #thermal-sensor-cells : Should be 1. See ./thermal.txt for a description.
-- #qcom,sensors: Number of sensors in tsens block
-- Refer to Documentation/devicetree/bindings/nvmem/nvmem.txt to know how to specify

-4. Event Notification
+4. Export Symbol APIs
=====================
-The framework includes a simple notification mechanism, in the form of a
-netlink event. Netlink socket initialization is done during the _init_
-of the framework. Drivers which intend to use the notification mechanism
-just need to call thermal_generate_netlink_event() with two arguments viz
-(originator, event). The originator is a pointer to struct thermal_zone_device
-from where the event has been originated. An integer which represents the
-thermal zone device will be used in the message to identify the zone. The
-event will be one of:{THERMAL_AUX0, THERMAL_AUX1, THERMAL_CRITICAL,
-THERMAL_DEV_FAULT}. Notification can be sent when the current temperature
-crosses any of the configured thresholds.

+is reset. This has no effect if called for a normal guest.

+This ioctl issues an ultravisor call to terminate the secure guest,
+unpins the VPA pages and releases all the device pages that are used to
+track the secure pages by hypervisor.

+ * Notes on locking
+ *
+ * kvm->arch.uvmem_lock is a per-guest lock that prevents concurrent
+ * page-in and page-out requests for the same GPA. Concurrent accesses
+ * can either come via UV (guest vCPUs requesting for same page)
+ * or when HV and guest simultaneously access the same page.
+ * This mutex serializes the migration of page from HV(normal) to
+ * UV(secure) and vice versa. So the serialization points are around
+ * migrate_vma routines and page-in/out routines.
+ *
+ * Per-guest mutex comes with a cost though. Mainly it serializes the
+ * fault path as page-out can occur when HV faults on accessing secure
+ * guest pages. Currently UV issues page-in requests for all the guest
+ * PFNs one at a time during early boot (UV_ESM uvcall), so this is
+ * not a cause for concern. Also currently the number of page-outs caused
+ * by HV touching secure pages is very very low. If an when UV supports
+ * overcommitting, then we might see concurrent guest driven page-outs.
+ *
+ * Locking order
+ *
+ * 1. kvm->srcu - Protects KVM memslots
+ * 2. kvm->mm->mmap_sem - find_vma, migrate_vma_pages and helpers, ksm_madvise
+ * 3. kvm->arch.uvmem_lock - protects read/writes to uvmem slots thus acting
+ * as sync-points for page-in/out
+ */
+
+/*
+ * Notes on page size
+ *
+ * Currently UV uses 2MB mappings internally, but will issue H_SVM_PAGE_IN
+ * and H_SVM_PAGE_OUT hcalls in PAGE_SIZE(64K) granularity. HV tracks
+ * secure GPAs at 64K page size and maintains one device PFN for each
+ * 64K secure GPA. UV_PAGE_IN and UV_PAGE_OUT calls by HV are also issued
+ * for 64K page at a time.

+ * faults and issues a UV_PAGE_OUT request with 64K page size. Currently
+ * UV splits and remaps the 2MB page if necessary and copies out the
+ * required 64K page contents.
+ *
+ * Shared pages: Whenever guest shares a secure page, UV will split and
+ * remap the 2MB page if required and issue H_SVM_PAGE_IN with 64K page size.
+ *
+ * HV invalidating a page: When a regular page belonging to secure
+ * guest gets unmapped, HV informs UV with UV_PAGE_INVAL of 64K
+ * page size. Using 64K page size is correct here because any non-secure
+ * page will essentially be of 64K page size. Splitting by UV during sharing
+ * and page-out ensures this.
+ *
+ * Page fault handling: When HV handles page fault of a page belonging
+ * to secure guest, it sends that to UV with a 64K UV_PAGE_IN request.
+ * Using 64K size is correct here too as UV would have split the 2MB page
+ * into 64k mappings and would have done page-outs earlier.
+ *
+ * In summary, the current secure pages handling code in HV assumes
+ * 64K page size and in fact fails any page-in/page-out requests of
+ * non-64K size upfront. If and when UV starts supporting multiple
+ * page-sizes, we need to break this assumption.

* To save constantly doing look ups on disk we keep an in core copy of the
* on-disk bitmap, the region_map.
*
- * To further reduce metadata I/O overhead we use a second bitmap, the dmap
- * (dirty bitmap), which tracks the dirty words, i.e. longs, of the region_map.
+ * In order to track which regions are hydrated during a metadata transaction,
+ * we use a second set of bitmaps, the dmap (dirty bitmap), which includes two
+ * bitmaps, namely dirty_regions and dirty_words. The dirty_regions bitmap
+ * tracks the regions that got hydrated during the current metadata
+ * transaction. The dirty_words bitmap tracks the dirty words, i.e. longs, of
+ * the dirty_regions bitmap.
+ *
+ * This allows us to precisely track the regions that were hydrated during the
+ * current metadata transaction and update the metadata accordingly, when we
+ * commit the current transaction. This is important because dm-clone should
+ * only commit the metadata of regions that were properly flushed to the
+ * destination device beforehand. Otherwise, in case of a crash, we could end
+ * up with a corrupted dm-clone device.
*
* When a region finishes hydrating dm-clone calls
* dm_clone_set_region_hydrated(), or for discard requests
* dm_clone_cond_set_range(), which sets the corresponding bits in region_map
* and dmap.
*
- * During a metadata commit we scan the dmap for dirty region_map words (longs)
- * and update accordingly the on-disk metadata. Thus, we don't have to flush to
- * disk the whole region_map. We can just flush the dirty region_map words.
+ * During a metadata commit we scan dmap->dirty_words and dmap->dirty_regions
+ * and update the on-disk metadata accordingly. Thus, we don't have to flush to
+ * disk the whole region_map. We can just flush the dirty region_map bits.
*
- * We use a dirty bitmap, which is smaller than the original region_map, to
- * reduce the amount of memory accesses during a metadata commit. As dm-bitset
- * accesses the on-disk bitmap in 64-bit word granularity, there is no
- * significant benefit in tracking the dirty region_map bits with a smaller
- * granularity.
+ * We use the helper dmap->dirty_words bitmap, which is smaller than the
+ * original region_map, to reduce the amount of memory accesses during a
+ * metadata commit. Moreover, as dm-bitset also accesses the on-disk bitmap in
+ * 64-bit word granularity, the dirty_words bitmap helps us avoid useless disk
+ * accesses.
*
* We could update directly the on-disk bitmap, when dm-clone calls either
* dm_clone_set_region_hydrated() or dm_clone_cond_set_range(), buts this
* e.g., in a hooked overwrite bio's completion routine, and further reduce the
* I/O completion latency.
*
- * We maintain two dirty bitmaps. During a metadata commit we atomically swap
- * the currently used dmap with the unused one. This allows the metadata update
- * functions to run concurrently with an ongoing commit.

+ * kcov_remote_start() and kcov_remote_stop() can be used to annotate a section
+ * of code in a kernel background thread to allow kcov to be used to collect
+ * coverage from that part of code.
+ *
+ * The handle argument of kcov_remote_start() identifies a code section that is
+ * used for coverage collection. A userspace process passes this handle to
+ * KCOV_REMOTE_ENABLE ioctl to make the used kcov device start collecting
+ * coverage for the code section identified by this handle.
+ *
+ * The usage of these annotations in the kernel code is different depending on
+ * the type of the kernel thread whose code is being annotated.
+ *
+ * For global kernel threads that are spawned in a limited number of instances
+ * (e.g. one USB hub_event() worker thread is spawned per USB HCD), each
+ * instance must be assigned a unique 4-byte instance id. The instance id is
+ * then combined with a 1-byte subsystem id to get a handle via
+ * kcov_remote_handle(subsystem_id, instance_id).
+ *
+ * For local kernel threads that are spawned from system calls handler when a
+ * user interacts with some kernel interface (e.g. vhost workers), a handle is
+ * passed from a userspace process as the common_handle field of the
+ * kcov_remote_arg struct (note, that the user must generate a handle by using
+ * kcov_remote_handle() with KCOV_SUBSYSTEM_COMMON as the subsystem id and an
+ * arbitrary 4-byte non-zero number as the instance id). This common handle
+ * then gets saved into the task_struct of the process that issued the
+ * KCOV_REMOTE_ENABLE ioctl. When this proccess issues system calls that spawn
+ * kernel threads, the common handle must be retrived via kcov_common_handle()
+ * and passed to the spawned threads via custom annotations. Those kernel
+ * threads must in turn be annotated with kcov_remote_start(common_handle) and
+ * kcov_remote_stop(). All of the threads that are spawned by the same process
+ * obtain the same handle, hence the name "common".
+ *
+ * See Documentation/dev-tools/kcov.rst for more details.
+ *
+ * Internally, this function looks up the kcov device associated with the
+ * provided handle, allocates an area for coverage collection, and saves the
+ * pointers to kcov and area into the current task_struct to allow coverage to
+ * be collected via __sanitizer_cov_trace_pc()
+ * In turns kcov_remote_stop() clears those pointers from task_struct to stop
+ * collecting coverage and copies all collected coverage into the kcov area.
