* 2.6.21 fix lba48 bug in libata fill_result_tf()Mark Lord2007-04-04
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Current 2.6.21 libata does the following: void ata_tf_read(struct ata_port *ap, struct ata_taskfile *tf) { struct ata_ioports *ioaddr = &ap->ioaddr; tf->command = ata_check_status(ap); ... if (tf->flags & ATA_TFLAG_LBA48) { iowrite8(tf->ctl | ATA_HOB, ioaddr->ctl_addr); tf->hob_feature = ioread8(ioaddr->error_addr); ... } } ... static void fill_result_tf(struct ata_queued_cmd *qc) { struct ata_port *ap = qc->ap; ap->ops->tf_read(ap, &qc->result_tf); qc->result_tf.flags = qc->tf.flags; } Based on this, those last two statements fill_result_tf() appear to me to be in the wrong order, in that the tf->flags are uninitialized at the point where tf_read() is invoked. So for lba48 commands, tf_read() won't be reading back the full lba48 register contents.. Correct? This patch corrects fill_result_tf() so that the flags get copied to result_tf before they are used by tf_read().

Basically the stack frame of scsi_send_eh_cmd() is what ends up in the sense buffer. Depending upon how pointers look on a given platform, you can end up getting sr_ioctl.c errors when you mount a cdrom. If the CDROM gives a check condition for GPCMD_GET_CONFIGURATION issued by drivers/cdrom/cdrom.c:cdrom_mmc_profile(), sr_ioctl will spit out this error message in sr_do_ioctl() with the way pointers are on sparc64: default: printk(KERN_ERR "%s: CDROM (ioctl) error, command: ", cd->cdi.name); __scsi_print_command(cgc->cmd); scsi_print_sense_hdr("sr", &sshdr); err = -EIO; This is the error Tom Callaway reported in: http://marc.info/?l=linux-sparc&m=117407453208101&w=2 Anyways, fix this by using page_address(sgl.page) which is OK because we know this is low-mem due to GFP_ATOMIC.

This patch is just to ignore the INTERNAL ERROR in such case. Without this patch, ahci error handler will report many errors as below: ----------- cut from dmesg ----------- ata9: soft resetting port ata9: SATA link up 1.5 Gbps (SStatus 113 SControl 300) ata9.00: configured for UDMA/33 ata9: EH complete ata9.00: exception Emask 0x40 SAct 0x0 SErr 0x800 action 0x2 ata9.00: (irq_stat 0x40000001) ata9.00: cmd a0/00:00:00:00:20/00:00:00:00:00/a0 tag 0 cdb 0x0 data 0 res 51/24:03:00:00:20/00:00:00:00:00/a0 Emask 0x40 (internal error) ata9: soft resetting port ata9: SATA link up 1.5 Gbps (SStatus 113 SControl 300) ata9.00: configured for UDMA/33 ata9: EH complete ata9.00: exception Emask 0x40 SAct 0x0 SErr 0x800 action 0x2 ata9.00: (irq_stat 0x40000001) ata9.00: cmd a0/01:00:00:00:00/00:00:00:00:00/a0 tag 0 cdb 0x43 data 12 in res 51/24:03:00:00:00/00:00:00:00:00/a0 Emask 0x40 (internal error) -------- end cut --------- Signed-off-by: Conke Hu <conke.hu@amd.com> Signed-off-by: Jeff Garzik <jeff@garzik.org>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Recent changes in the specs that were introduced in commit 740ac4fb08866d702be90f167665d03759bd27d0 were incorrect and resulted in machine check errors on the PPC architecture for G PHY's with a revision number equal to 1. The two offending changes are reverted. Signed-off-by: David Woodhouse <dwmw2@infradead.org> Signed-off-by: Larry Finger <Larry.Finger@lwfinger.net> Signed-off-by: John W.

| | |/ / | |/| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | There are several places where the PHY version and revision were interchanged. These are changed in the specifications on 2/13/07 and now use "analog" instead instead of "version" to help reduce confusion.
