Donenfeld" , Samuel Neves , Andy Lutomirski , Thomas Gleixner , linux-arch@vger.kernel.org Subject: [PATCH net-next v8 02/28] asm: simd context helper API Date: Thu, 18 Oct 2018 16:56:46 +0200 Message-Id: <20181018145712.7538-3-Jason@zx2c4.com> In-Reply-To: <20181018145712.7538-1-Jason@zx2c4.com> References: <20181018145712.7538-1-Jason@zx2c4.com> MIME-Version: 1.0 Sender: netdev-owner@vger.kernel.org Precedence: bulk List-ID: X-Mailing-List: netdev@vger.kernel.org Sometimes it's useful to amortize calls to XSAVE/XRSTOR and the related FPU/SIMD functions over a number of calls, because FPU restoration is quite expensive. This adds a simple header for carrying out this pattern: simd_context_t simd_context; simd_get(&simd_context); while ((item = get_item_from_queue()) != NULL) { encrypt_item(item, &simd_context); simd_relax(&simd_context); } simd_put(&simd_context); The relaxation step ensures that we don't trample over preemption, and the get/put API should be a familiar paradigm in the kernel. On the other end, code that actually wants to use SIMD instructions can accept this as a parameter and check it via: void encrypt_item(struct item *item, simd_context_t *simd_context) { if (item->len > LARGE_FOR_SIMD && simd_use(simd_context)) wild_simd_code(item); else boring_scalar_code(item); } The actual XSAVE happens during simd_use (and only on the first time), so that if the context is never actually used, no performance penalty is hit.

Sum of 2^m n-m-bit numbers and n-bit + @ one is n+1 bits wide. + @ + @ >>+ denotes Hnext += Hn>>26, Hn &= 0x3ffffff. This means that + @ H0, H2, H3 are guaranteed to be 26 bits wide, while H1 and H4 + @ can be 27. However! In cases when their width exceeds 26 bits + @ they are limited by 2^26+2^6. This in turn means that *sum* + @ of the products with these values can still be viewed as sum + @ of 52-bit numbers as long as the amount of addends is not a + @ power of 2. For example, + @ + @ H4 = H4*R0 + H3*R1 + H2*R2 + H1*R3 + H0 * R4, + @ + @ which can't be larger than 5 * (2^26 + 2^6) * (2^26 + 2^6), or + @ 5 * (2^52 + 2*2^32 + 2^12), which in turn is smaller than + @ 8 * (2^52) or 2^55. However, the value is then multiplied by + @ by 5, so we should be looking at 5 * 5 * (2^52 + 2^33 + 2^12), + @ which is less than 32 * (2^52) or 2^57. And when processing + @ data we are looking at triple as many addends... + @ + @ In key setup procedure pre-reduced H0 is limited by 5*4+1 and + @ 5*H4 - by 5*5 52-bit addends, or 57 bits. But when hashing the + @ input H0 is limited by (5*4+1)*3 addends, or 58 bits, while + @ 5*H4 by 5*5*3, or 59[!] bits.

Originally this used AVX-512F, but Skylake thermal throttling made AVX-512VL more attractive and possible to do with negligable difference. Signed-off-by: Jason A.
