From e922da40befdbaa89cd85d3154b4a9cea8880fa0 Mon Sep 17 00:00:00 2001 From: Oswald Buddenhagen Date: Sat, 22 Apr 2023 14:15:19 +0200 Subject: [PATCH] ALSA: emu10k1: minor optimizations - In snd_emu10k1_look_for_ctl(), evaluate the cheap condition first - In _snd_emu10k1_{audigy_,}init_efx(), don't use expensive bit setting loops to fill arrays - In snd_emu_proc_ptr_reg_read(), remove useless condition - iobase can be only 0 or 0x20 Signed-off-by: Oswald Buddenhagen Link: https://lore.kernel.org/r/20230422121519.1052813-1-oswald.buddenhagen@gmx.de Signed-off-by: Takashi Iwai --- sound/pci/emu10k1/emufx.c | 18 +++++++----------- sound/pci/emu10k1/emuproc.c | 5 +---- 2 files changed, 8 insertions(+), 15 deletions(-) diff --git a/sound/pci/emu10k1/emufx.c b/sound/pci/emu10k1/emufx.c index c74e66e03ae0..6a51aed59238 100644 --- a/sound/pci/emu10k1/emufx.c +++ b/sound/pci/emu10k1/emufx.c @@ -641,8 +641,8 @@ snd_emu10k1_look_for_ctl(struct snd_emu10k1 *emu, list_for_each_entry(ctl, &emu->fx8010.gpr_ctl, list) { kcontrol = ctl->kcontrol; if (kcontrol->id.iface == id->iface && - !strcmp(kcontrol->id.name, id->name) && - kcontrol->id.index == id->index) + kcontrol->id.index == id->index && + !strcmp(kcontrol->id.name, id->name)) return ctl; } return NULL; @@ -1213,7 +1213,7 @@ static int snd_emu10k1_audigy_dsp_convert_32_to_2x16( static int _snd_emu10k1_audigy_init_efx(struct snd_emu10k1 *emu) { - int err, i, z, gpr, nctl; + int err, z, gpr, nctl; int bit_shifter16; const int playback = 10; const int capture = playback + (SND_EMU10K1_PLAYBACK_CHANNELS * 2); /* we reserve 10 voices */ @@ -1245,12 +1245,10 @@ static int _snd_emu10k1_audigy_init_efx(struct snd_emu10k1 *emu) icode->code = icode->tram_addr_map + 256; /* clear free GPRs */ - for (i = 0; i < 512; i++) - set_bit(i, icode->gpr_valid); + memset(icode->gpr_valid, 0xff, 512 / 8); /* clear TRAM data & address lines */ - for (i = 0; i < 256; i++) - set_bit(i, icode->tram_valid); + memset(icode->tram_valid, 0xff, 256 / 8); strcpy(icode->name, "Audigy DSP code for ALSA"); ptr = 0; @@ -1886,12 +1884,10 @@ static int _snd_emu10k1_init_efx(struct snd_emu10k1 *emu) icode->code = icode->tram_addr_map + 160; /* clear free GPRs */ - for (i = 0; i < 256; i++) - set_bit(i, icode->gpr_valid); + memset(icode->gpr_valid, 0xff, 256 / 8); /* clear TRAM data & address lines */ - for (i = 0; i < 160; i++) - set_bit(i, icode->tram_valid); + memset(icode->tram_valid, 0xff, 160 / 8); strcpy(icode->name, "SB Live!
