From cf4a7207b1cb4a3c3fe3aa11a83c9d673722a7f5 Mon Sep 17 00:00:00 2001 From: Chris Wilson Date: Thu, 22 Dec 2016 14:45:14 +0000 Subject: lib: Add a simple prime number generator Prime numbers are interesting for testing components that use multiplies and divides, such as testing DRM's struct drm_mm alignment computations. v2: Move to lib/, add selftest v3: Fix initial constants (exclude 0/1 from being primes) v4: More RCU markup to keep 0day/sparse happy v5: Fix RCU unwind on module exit, add to kselftests v6: Tidy computation of bitmap size v7: for_each_prime_number_from() v8: Compose small-primes using BIT() for easier verification v9: Move rcu dance entirely into callers. v10: Improve quote for Betrand's Postulate (aka Chebyshev's theorem) Signed-off-by: Chris Wilson Cc: Lukas Wunner Reviewed-by: Joonas Lahtinen Signed-off-by: Daniel Vetter Link: http://patchwork.freedesktop.org/patch/msgid/20161222144514.3911-1-chris@chris-wilson.co.uk --- lib/Makefile | 2 ++ 1 file changed, 2 insertions(+) (limited to 'lib/Makefile') diff --git a/lib/Makefile b/lib/Makefile index 50144a3aeebd..c664143fd917 100644 --- a/lib/Makefile +++ b/lib/Makefile @@ -197,6 +197,8 @@ obj-$(CONFIG_ASN1) += asn1_decoder.o obj-$(CONFIG_FONT_SUPPORT) += fonts/ +obj-$(CONFIG_PRIME_NUMBERS) += prime_numbers.o + hostprogs-y := gen_crc32table clean-files := crc32table.h -- cgit v1.2.3
