From a29fdd3c2a3e53b67baa5031372fd78fddaf48fa Mon Sep 17 00:00:00 2001 From: James Bottomley Date: Thu, 15 Feb 2007 15:25:35 -0600 Subject: [SCSI] aic94xx: tie driver to the major number of the sequencer firmware The sequencer firmware file has both a string (currently showing V17/10c6) and a number (currently set to 1.1). It has become apparent that Adaptec may issue sequencer firmware in the future which could be incompatible with the current driver. Therefore, the driver will be tied to the particular major number of the firmware (i.e. the current driver will load any 1.x firmware). Additionally, the driver will print out both the ascii string and the major number, so with this pach the current firmware will print out aic94xx: Found sequencer firmware version 1.1 (V17/10c6) Signed-off-by: James Bottomley --- drivers/scsi/aic94xx/aic94xx_seq.c | 13 ++++++++++--- drivers/scsi/aic94xx/aic94xx_seq.h | 1 + 2 files changed, 11 insertions(+), 3 deletions(-) diff --git a/drivers/scsi/aic94xx/aic94xx_seq.c b/drivers/scsi/aic94xx/aic94xx_seq.c index eae7a247bec..c750fbf7013 100644 --- a/drivers/scsi/aic94xx/aic94xx_seq.c +++ b/drivers/scsi/aic94xx/aic94xx_seq.c @@ -44,7 +44,6 @@ #define PAUSE_TRIES 1000 static const struct firmware *sequencer_fw; -static const char *sequencer_version; static u16 cseq_vecs[CSEQ_NUM_VECS], lseq_vecs[LSEQ_NUM_VECS], mode2_task, cseq_idle_loop, lseq_idle_loop; static u8 *cseq_code, *lseq_code; @@ -1276,7 +1275,6 @@ static int asd_request_firmware(struct asd_ha_struct *asd_ha) header.csum = le32_to_cpu(hdr_ptr->csum); header.major = le32_to_cpu(hdr_ptr->major); header.minor = le32_to_cpu(hdr_ptr->minor); - sequencer_version = hdr_ptr->version; header.cseq_table_offset = le32_to_cpu(hdr_ptr->cseq_table_offset); header.cseq_table_size = le32_to_cpu(hdr_ptr->cseq_table_size); header.lseq_table_offset = le32_to_cpu(hdr_ptr->lseq_table_offset); @@ -1303,6 +1301,16 @@ static int asd_request_firmware(struct asd_ha_struct *asd_ha) return -EINVAL; } + asd_printk("Found sequencer Firmware version %d.%d (%s)\n", + header.major, header.minor, hdr_ptr->version); + + if (header.major != SAS_RAZOR_SEQUENCER_FW_MAJOR) { + asd_printk("Firmware Major Version Mismatch;" + "driver requires version %d.X", + SAS_RAZOR_SEQUENCER_FW_MAJOR); + return -EINVAL; + } + ptr_cseq_vecs = (u16 *)&sequencer_fw->data[header.cseq_table_offset]; ptr_lseq_vecs = (u16 *)&sequencer_fw->data[header.lseq_table_offset]; mode2_task = header.mode2_task; @@ -1335,7 +1343,6 @@ int asd_init_seqs(struct asd_ha_struct *asd_ha) return err; } - asd_printk("using sequencer %s\n", sequencer_version); err = asd_seq_download_seqs(asd_ha); if (err) { asd_printk("couldn't download sequencers for %s\n", diff --git a/drivers/scsi/aic94xx/aic94xx_seq.h b/drivers/scsi/aic94xx/aic94xx_seq.h index 9437ff0ae3a..2ea6a0d5220 100644 --- a/drivers/scsi/aic94xx/aic94xx_seq.h +++ b/drivers/scsi/aic94xx/aic94xx_seq.h @@ -31,6 +31,7 @@ #define LSEQ_NUM_VECS 11 #define SAS_RAZOR_SEQUENCER_FW_FILE "aic94xx-seq.fw" +#define SAS_RAZOR_SEQUENCER_FW_MAJOR 1 /* Note: All quantites in the sequencer file are little endian */ struct sequencer_file_header { -- cgit v1.2.3-70-g09d2
