      [PATCH] sata_sil24: convert to new probing mechanism and add hotplug support · 0542925b
      由 Tejun Heo 提交于 
      Convert to new probing mechanism and add hotplug support by enabling
PORT_IRQ_PHYRDY_CHG, marking ehi for hotplug and scheduling EH on
PORT_IRQ_PHYRDY_CHG or PORT_IRQ_DEV_XCHG.

Sil3124/32 family of controllers don't have any mechanism to wait for
the first D2H FIS after hotplug, so ATA_FLAG_SKIP_D2H_BSY is used.

      [PATCH] sata_sil24: update sil24_hardreset() · e8e008e7
      由 Tejun Heo 提交于 
      Use phy debouncing instead of unconditional wait after DEV_RST and
make sil24_hardreset() to request followup SRST as that's the only way
to wait for !BSY.  Note that the original implementation never worked
- if the cached status was !BSY, ata_busy_sleep() finished
immediately; otherwise, it timed out regardless of the actual device
status.

      [PATCH] sata_sil24: rename PORT_PRB to PORT_LRAM and add PORT_LRAM_SLOT_SZ · 135da345
      由 Tejun Heo 提交于 
      PORT_PRB is a misnomer as the area also contains other stuff.  Rename
it to PORT_LRAM and add PORT_LRAM_SLOT_SZ.

      [PATCH] libata-hp-prep: add prereset() method and implement ata_std_prereset() · f5914a46
      由 Tejun Heo 提交于 
      With hotplug, every reset might be a probing reset and thus something
similar to probe_init() is needed.  prereset() method is called before
a series of resets to a port and is the counterpart of postreset().
prereset() can tell EH to use different type of reset or skip reset by
modifying ehc->i.action.

This patch also implements ata_std_prereset().  Most controllers
should be able to use this function directly or with some wrapping.
After hotplug, different controllers need different actions to resume
the PHY and detect the newly attached device.  Controllers can be
categorized as follows.

* Controllers which can wait for the first D2H FIS after hotplug.
  Note that if the waiting is implemented by polling TF status, there
  needs to be a way to set BSY on PHY status change.  It can be
  implemented by hardware or with the help of the driver.

* Controllers which can wait for the first D2H FIS after sending
  COMRESET.  These controllers need to issue COMRESET to wait for the
  first FIS.  Note that the received D2H FIS could be the first D2H
  FIS after POR (power-on-reset) or D2H FIS in response to the
  COMRESET.  Some controllers use COMRESET as TF status
  synchronization point and clear TF automatically (sata_sil).

* Controllers which cannot wait for the first D2H FIS reliably.
  Blindly issuing SRST to spinning-up device often results in command
  issue failure or timeout, causing extended delay.  For these
  controllers, ata_std_prereset() explicitly waits ATA_SPINUP_WAIT
  (currently 8s) to give newly attached device time to spin up, then
  issues reset.  Note that failing to getting ready in ATA_SPINUP_WAIT
  is not critical.  libata will retry.  So, the timeout needs to be
  long enough to spin up most devices.

LLDDs can tell ata_std_prereset() which of above action is needed with
ATA_FLAG_HRST_TO_RESUME and ATA_FLAG_SKIP_D2H_BSY flags.  These flags
are PHY-specific property and will be moved to ata_link later.

While at it, this patch unifies function typedef's such that they all
have named arguments.

      [PATCH] sata_sil24: lengthen softreset timeout · 8645984c
      由 Tejun Heo 提交于 
      sil24 softreset timeout was > 100ms (100 loops with msleep(1)), which
turned out to be too short for some devices (ASI ARAID99 2000).  This
patch converts sil24 softreset waiting loop to use proper timeout
condition and lengthen the timeout to ATA_TMOUT_BOOT secs and check
interval to 100ms.  Chisato Yamauchi discovered the problem and
supplied initial patch.

      [PATCH] sata_sil24: exit early from softreset if SStatus reports no device · 10d996ad
      由 Tejun Heo 提交于 
      sata_sil24 softreset routine used to check sata_dev_present() after
SRST is complete in the hope that SRST may do some good even when
SStatus reports no device.  This is okay as long as SRST timeout is
short (> 100ms in the current code) but it seems that not all SATA
devices are happy with short SRST timeout.

This patch makes softreset exit early without performing actual SRST
if SStatus reports no device in preparation for lengthening SRST
timeout.
