[PATCH v1] lib/hashtable_test.c: add test for the hashtable structure

by Rae Moar

Add a KUnit test for the kernel hashtable implementation in include/linux/hashtable.h. Note that this version does not yet test each of the rcu alternative versions of functions. Signed-off-by: Rae Moar <rmoar(a)google.com> --- Note: The check patch script is outputting open brace errors on lines 154, 186, 231 of lib/hashtable_test.c but I believe the format of the braces on those lines is consistent with the Linux Kernel style guide. Will continue to look at these errors. lib/Kconfig.debug | 13 ++ lib/Makefile | 1 + lib/hashtable_test.c | 299 +++++++++++++++++++++++++++++++++++++++++++ 3 files changed, 313 insertions(+) create mode 100644 lib/hashtable_test.c diff --git a/lib/Kconfig.debug b/lib/Kconfig.debug index 3fc7abffc7aa..3cf3b6f8cff4 100644 --- a/lib/Kconfig.debug +++ b/lib/Kconfig.debug @@ -2458,6 +2458,19 @@ config LIST_KUNIT_TEST If unsure, say N. +config HASHTABLE_KUNIT_TEST + tristate "KUnit Test for Kernel Hashtable structures" if !KUNIT_ALL_TESTS + depends on KUNIT + default KUNIT_ALL_TESTS + help + This builds the hashtable KUnit test suite. + It tests the API and basic functionality of the functions + and associated macros defined in include/linux/hashtable.h. + For more information on KUnit and unit tests in general please refer + to the KUnit documentation in Documentation/dev-tools/kunit/. + + If unsure, say N. + config LINEAR_RANGES_TEST tristate "KUnit test for linear_ranges" depends on KUNIT diff --git a/lib/Makefile b/lib/Makefile index 161d6a724ff7..9036d3aeee0a 100644 --- a/lib/Makefile +++ b/lib/Makefile @@ -370,6 +370,7 @@ obj-$(CONFIG_PLDMFW) += pldmfw/ CFLAGS_bitfield_kunit.o := $(DISABLE_STRUCTLEAK_PLUGIN) obj-$(CONFIG_BITFIELD_KUNIT) += bitfield_kunit.o obj-$(CONFIG_LIST_KUNIT_TEST) += list-test.o +obj-$(CONFIG_HASHTABLE_KUNIT_TEST) += hashtable_test.o obj-$(CONFIG_LINEAR_RANGES_TEST) += test_linear_ranges.o obj-$(CONFIG_BITS_TEST) += test_bits.o obj-$(CONFIG_CMDLINE_KUNIT_TEST) += cmdline_kunit.o diff --git a/lib/hashtable_test.c b/lib/hashtable_test.c new file mode 100644 index 000000000000..7907df66a8e7 --- /dev/null +++ b/lib/hashtable_test.c @@ -0,0 +1,299 @@ +// SPDX-License-Identifier: GPL-2.0 +/* + * KUnit test for the Kernel Hashtable structures. + * + * Copyright (C) 2022, Google LLC. + * Author: Rae Moar <rmoar(a)google.com> + */ +#include <kunit/test.h> + +#include <linux/hashtable.h> + +struct hashtable_test_entry { + int key;

[PATCH] selftests:dma: Fix compile error in user-space tool

by Gerd Bayer

Since [1] the user-space program dma_map_benchmark shares the header file linux/map_benchmark.h with the kernel driver in kernel/dma/map_benchmark.c. With latest kernel version this does not compile anymore. While https://kernelnewbies.org/KernelHeaders suggests otherwise, allow it to use kernel headers through the uapi/ include directory. I assume we can do so safely, since the controlling user-space program is distributed with the kernel. With this change dma_map_benchmark compiles with just the obvious warning about uapi usage on ARCH=x86, arm64, and s390 and runs on ARCH=s390. [1] commit 8ddde07a3d28 ("dma-mapping: benchmark: extract a common header file for map_benchmark definition") Signed-off-by: Gerd Bayer <gbayer(a)linux.ibm.com> Acked-by: Xiang Chen <chenxiang66(a)hisilicon.com> --- tools/testing/selftests/dma/dma_map_benchmark.c | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) diff --git a/tools/testing/selftests/dma/dma_map_benchmark.c b/tools/testing/selftests/dma/dma_map_benchmark.c index 5c997f17fcbd..d49d7ea6a63e 100644 --- a/tools/testing/selftests/dma/dma_map_benchmark.c +++ b/tools/testing/selftests/dma/dma_map_benchmark.c @@ -10,7 +10,7 @@ #include <unistd.h> #include <sys/ioctl.h> #include <sys/mman.h> -#include <linux/types.h> +#include <uapi/linux/types.h> #include <linux/map_benchmark.h> #define NSEC_PER_MSEC 1000000L base-commit: 1fe4fd6f5cad346e598593af36caeadc4f5d4fa9 -- 2.39.0

[PATCH] kselftest/arm64: Skip non-power of 2 SVE vector lengths in fp-stress

by Mark Brown

As documented in issue C215 in the known issues list for DDI0487I.a [1] Arm will be making a retroactive change to SVE to remove the possibility of selecting non power of two vector lengths. This has no impact on existing physical implementations but most virtual implementations have implemented the full range of permissible vector lengths. Given how demanding fp-stress is for these implementations update to only attempt to enumerate the power of two vector lengths, reducing the load created on existing virtual implementations and only exercising the functionality that will be seen in physical implementations.
