From 8b881b0410de0f72a43e814393abf3a4cb29ebb4 Mon Sep 17 00:00:00 2001 From: Jeff Garzik Date: Sun, 11 Jun 2006 09:59:27 -0400 Subject: [PATCH] [ATA] Increase lba48 max-sectors from 200 to 256. Also, moved ATA_MAX_SECTORS and ATA_MAX_SECTORS_LBA48 from linux/libata.h to linux/ata.h, now that they truly reflect the standard (well... mostly; note TODO comment). This changes the performance profile (and potential bug profile) for a bunch of drivers, so be wary. --- include/linux/ata.h | 2 ++ include/linux/libata.h | 2 -- 2 files changed, 2 insertions(+), 2 deletions(-) diff --git a/include/linux/ata.h b/include/linux/ata.h index 3671af869696..8d708a3d505b 100644 --- a/include/linux/ata.h +++ b/include/linux/ata.h @@ -40,6 +40,8 @@ enum { ATA_MAX_DEVICES = 2, /* per bus/port */ ATA_MAX_PRD = 256, /* we could make these 256/256 */ ATA_SECT_SIZE = 512, + ATA_MAX_SECTORS = 256, + ATA_MAX_SECTORS_LBA48 = 65535,/* TODO: 65536? */ ATA_ID_WORDS = 256, ATA_ID_SERNO_OFS = 10, diff --git a/include/linux/libata.h b/include/linux/libata.h index ed749f778697..060da736b3a8 100644 --- a/include/linux/libata.h +++ b/include/linux/libata.h @@ -114,8 +114,6 @@ enum { /* tag ATA_MAX_QUEUE - 1 is reserved for internal commands */ ATA_MAX_QUEUE = 32, ATA_TAG_INTERNAL = ATA_MAX_QUEUE - 1, - ATA_MAX_SECTORS = 200, /* FIXME */ - ATA_MAX_SECTORS_LBA48 = 65535, ATA_MAX_BUS = 2, ATA_DEF_BUSY_WAIT = 10000, ATA_SHORT_PAUSE = (HZ >> 6) + 1, -- 2.39.5
