[PATCHSET libata-dev#upstream] clean up scsi_host_templates and ata_port_operations, take #2

[Tejun Heo]

Hello, all.

This is the second take of cleanup-sht-ops patchset.  As the name
suggests it reorganizes and cleans up scsi_host_template and
ata_port_operation tables used by libata core and low level drivers.

Please read the head message of the last take[L] for more info.
Changes from the last take[L] are...

* Updated to fit the current upstream.  sata_mv should be fine now.

* sht and ops conversions separated into two patches as Jeff
  requested.

* Instead of using init-register model for SFF drivers which need to
  initialize host->private_data, @host_priv is added to
  ata_pci_init_one() as Alan requested.

* pata_scc should now have NULL thaw after conversion.

The following drivers need specific platform to build, so they need
verification.  If you work on one of the following drivers, please
verify that the driver builds and works fine.  It would be best if you
can verify that the sht and ops don't change by the fifth and sixth
patches using the method I'll write in another message.

* pata_at32
* pata_bf54x
* pata_icside
* pata_ixp4xx_cf
* pata_mpc52xx
* pata_scc
* sata_fsl

This patchset is on top of

  upstream (bc5468f52b785ffa1fe0ea289baec2c51384d436)
+ prefer-hardreset patchset [1]
+ grace-failure-on-no-reset patch [2]

[PATCH 01/10] libata: PCI device should be powered up before being accessed

[Tejun Heo]

PCI device should be powered up or powered up before its PCI regsiters
are accessed.  Although PCI configuration register access is allowed
in D3hot, PCI device is free to reset its status when transiting from
D3hot to D0 causing configuration data to change.

Many libata SFF drivers which use ata_pci_init_one() read and update
configuration registers before calling ata_pci_init_one() which
enables the PCI device.  Also, in resume paths, some drivers access
registers without resuming the PCI device.

This patch adds a call to pcim_enable_device() in init path if
register is accessed before calling ata_pci_init_one() and make resume
paths first resume PCI devices, access PCI configuration regiters then
resume ATA host.

While at it...

* cmd640 was strange in that it set ->resume even when CONFIG_PM is
  not.  This is by-product of minimal build fix.  Updated.

* In cs5530, Don't BUG() on reinit failure.  Just whine and fail
  resume.

[PATCH 02/10] libata: reorganize ata_port_operations

[Tejun Heo]

Over the time, ops in ata_port_operations has become a bit confusing.
Reorganize.  SFF/BMDMA ops are separated into separate a group as they
will be taken out of ata_port_operations later.

[PATCH 03/10] libata: implement and use ata_noop_irq_clear()

[Tejun Heo]

->irq_clear() is used to clear IRQ bit of a SFF controller and isn't
useful for drivers which don't use libata SFF HSM implementation.
However, it's a required callback and many drivers implement their own
noop version as placeholder.  This patch implements ata_noop_irq_clear
and use it to replace those custom placeholders.

Also, SFF drivers which don't support BMDMA don't need to use
ata_bmdma_irq_clear().  It becomes noop if BMDMA address isn't
initialized.  Convert them to use ata_noop_irq_clear().

[PATCH 04/10] libata: normalize port_info, port_operations and sht tables

[Tejun Heo]

Over the time, port info, ops and sht structures developed quite a bit
of inconsistencies.  This patch updates drivers.

* Enable/disable_pm callbacks added to all ahci ops tables.

* Every driver for SFF controllers now uses ata_sff_port_start()
  instead of ata_port_start() unless the driver has custom
  implementation.

* Every driver for SFF controllers now uses ata_pci_default_filter()
  unless the driver has custom implementation.

* Removed an odd port_info->sht initialization from ata_piix.c.
  Likely a merge byproduct.

* A port which has ATA_FLAG_SATA set doesn't need to set cable_detect
  to ata_cable_sata().  Remove it from via and mv port ops.

* Some drivers had unnecessary .max_sectors initialization which is
  ignored and was missing .slave_destroy callback.  Fixed.

* Removed unnecessary sht initializations port_info's.

* Removed onsolete scsi device suspend/resume callbacks from
  pata_bf54x.

* No reason to set ata_pci_default_filter() and bmdma functions for
  PIO-only drivers.  Remove those callbacks and replace
  ata_bmdma_irq_clear with ata_noop_irq_clear.

* pata_platform sets port_start to ata_dummy_ret0.  port_start can
  just be set to NULL.

* sata_fsl supports NCQ but was missing qc_defer.  Fixed.

[PATCH 05/10] libata: implement and use SHT initializers

[Tejun Heo]

libata lets low level drivers build scsi_host_template and register it
to the SCSI layer.  This allows low level drivers high level of
flexibility but also burdens them with lots of boilerplate entries.

This patch implements SHT initializers which can be used to initialize
all the boilerplate entries in a sht.  Three variants of them are
implemented - BASE, BMDMA and NCQ - for different types of drivers.
Note that entries can be overriden by putting individual initializers
after the helper macro.

All sht tables are identical before and after this patch.

[PATCH 06/10] libata: implement and use ops inheritance

[Tejun Heo]

libata lets low level drivers build ata_port_operations table and
register it with libata core layer.  This allows low level drivers
high level of flexibility but also burdens them with lots of
boilerplate entries.

This becomes worse for drivers which support related similar
controllers which differ slightly.  They share most of the operations
except for a few.  However, the driver still needs to list all
operations for each variant.  This results in large number of
duplicate entries, which is not only inefficient but also error-prone
as it becomes very difficult to tell what the actual differences are.

This duplicate boilerplates all over the low level drivers also make
updating the core layer exteremely difficult and error-prone.  When
compounded with multi-branched development model, it ends up
accumulating inconsistencies over time.  Some of those inconsistencies
cause immediate problems and fixed.  Others just remain there dormant
making maintenance increasingly difficult.

To rectify the problem, this patch implements ata_port_operations
inheritance.  To allow LLDs to easily re-use their own ops tables
overriding only specific methods, this patch implements poor man's
class inheritance.  An ops table has ->inherits field which can be set
to any ops table as long as it doesn't create a loop.  When the host
is started, the inheritance chain is followed and any operation which
isn't specified is taken from the nearest ancestor which has it
specified.  This operation is called finalization and done only once
per an ops table and the LLD doesn't have to do anything special about
it other than making the ops table non-const such that libata can
update it.

libata provides four base ops tables lower drivers can inherit from -
base, sata, pmp, sff and bmdma.  To avoid overriding these ops
accidentaly, these ops are declared const and LLDs should always
inherit these instead of using them directly.

After finalization, all the ops table are identical before and after
the patch except for setting .irq_handler to ata_interrupt in drivers
which didn't use to.  The .irq_handler doesn't have any actual effect
and the field will soon be removed by later patch.

* sata_sx4 is still using old style EH and currently doesn't take
  advantage of ops inheritance.

[PATCH 07/10] libata: make ata_pci_init_one() not use ops->irq_handler and pi->sht

[Tejun Heo]

ata_pci_init_one() is the only function which uses ops->irq_handler
and pi->sht.  Other initialization functions take the same information
as arguments.  This causes confusion and duplicate unused entries in
structures.

Make ata_pci_init_one() take sht as an argument and use ata_interrupt
implicitly.  All current users use ata_interrupt and if different irq
handler is necessary open coding ata_pci_init_one() using
ata_prepare_sff_host() and ata_activate_sff_host can be done under ten
lines including error handling and driver which requires custom
interrupt handler is likely to require custom initialization anyway.

As ata_pci_init_one() was the last user of ops->irq_handler, this
patch also kills the field.

[PATCH 08/10] libata: stop overloading port_info->private_data

[Tejun Heo]

port_info->private_data is currently used for two purposes - to record
private data about the port_info or to specify host->private_data to
use when allocating ata_host.

This overloading is confusing and counter-intuitive in that
port_info->private_data becomes host->private_data instead of
port->private_data.  In addition, port_info and host don't correspond
to each other 1-to-1.  Currently, the first non-NULL
port_info->private_data is used.

This patch makes port_info->private_data just be what it is -
private_data for the port_info where LLD can jot down extra info.
libata no longer sets host->private_data to the first non-NULL
port_info->private_data, @host_priv argument is added to
ata_pci_init_one() instead.  LLDs which use ata_pci_init_one() can use
this argument to pass in pointer to host private data.  LLDs which
don't should use init-register model anyway and can initialize
host->private_data directly.

Adding @host_priv instead of using init-register model for LLDs which
use ata_pci_init_one() is suggested by Alan Cox.

[PATCH 09/10] libata: kill port_info->sht and ->irq_handler

[Tejun Heo]

libata core layer doesn't care about sht or ->irq_handler.  Those are
only of interest to the LLD during initialization.  This is confusing
and has caused several drivers to have duplicate unused initializers
for these fields.

Currently only sata_nv uses these fields.  Make sata_nv use
->private_data, which is supposed to carry LLD-specific information,
instead and kill ->sht and ->irq_handler.  nv_pi_priv structure is
defined and struct literals are used to initialize private_data.
Notational overhead is negligible.

[PATCH 10/10] libata: make reset related methods proper port operations

[Tejun Heo]

Currently reset methods are not specified directly in the
ata_port_operations table.  If a LLD wants to use custom reset
methods, it should construct and use a error_handler which uses those
reset methods.  It's done this way for two reasons.

First, the ops table already contained too many methods and adding
four more of them would noticeably increase the amount of necessary
boilerplate code all over low level drivers.

Second, as ->error_handler uses those reset methods, it can get
confusing.  ie. By overriding ->error_handler, those reset ops can be
made useless making layering a bit hazy.

Now that ops table uses inheritance, the first problem doesn't exist
anymore.  The second isn't completely solved but is relieved by
providing default values - most drivers can just override what it has
implemented and don't have to concern itself about higher level
callbacks.  In fact, there currently is no driver which actually
modifies error handling behavior.  Drivers which override
->error_handler just wraps the standard error handler only to prepare
the controller for EH.  I don't think making ops layering strict has
any noticeable benefit.

This patch makes ->prereset, ->softreset, ->hardreset, ->postreset and
their PMP counterparts propoer ops.  Default ops are provided in the
base ops tables and drivers are converted to override individual reset
methods instead of creating custom error_handler.

* ata_std_error_handler() doesn't use sata_std_hardreset() if SCRs
  aren't accessible.  sata_promise doesn't need to use separate
  error_handlers for PATA and SATA anymore.

* softreset is broken for sata_inic162x and sata_sx4.  As libata now
  always prefers hardreset, this doesn't really matter but the ops are
  forced to NULL using ATA_OP_NULL for documentation purpose.

* pata_hpt374 needs to use different prereset for the first and second
  PCI functions.  This used to be done by branching from
  hpt374_error_handler().  The proper way to do this is to use
  separate ops and port_info tables for each function.  Converted.

How to verify sht-ops-conversion patch doesn't change anything

[Tejun Heo]

The fifth and sixth patch, cleanup-sht and cleanup-ops, can be
verified not to change the final sht and ops by printing out all
entries and comparing the values before and after.

1. Get the following git branch.

   http://git.kernel.org/?p=linux/kernel/git/tj/libata-dev.git;a=shortlog;h=cleanup-sht-ops-verify-before
   git://git.kernel.org/pub/scm/linux/kernel/git/tj/libata-dev.git cleanup-sht-ops-verify-before

   Build the kernel with the libata modules to verify and run the
   following command.

   # insmod libata.ko; for i in $(ls *.ko | sort | grep -v libata.ko); do insmod $i; done; dmesg -c | grep -E 'SHT|OPS' | sed -r 's/^\[[ \.0-9]*\] (.*)$/\1/' | sort > ~/out.before

   If you need some libata modules built-in for rootfs, it's okay too.
   It will give the same result.

2. Get the following git branch.

   http://git.kernel.org/?p=linux/kernel/git/tj/libata-dev.git;a=shortlog;h=cleanup-sht-ops-verify-after
   git://git.kernel.org/pub/scm/linux/kernel/git/tj/libata-dev.git cleanup-sht-ops-verify-after

   # insmod libata.ko; for i in $(ls *.ko | sort | grep -v libata.ko); do insmod $i; done; dmesg -c | grep -E 'SHT|OPS' | sed -r 's/^\[[ \.0-9]*\] (.*)$/\1/' | sort > ~/out.after

3. Use your favorite diff program to compare out.before and out.after.
   Graphical ones which show in-line differences will work best.

Thanks.

I'm sorry. This is a bug.
Please use default thaw (ata_bmdma_thaw) for pata_scc.

Cheers

That change should be a separate patch.  This patchset shouldn't change
any actual behavior but adding ata_bmdma_thaw does change the behavior.
 Can you please submit a separate patch to fix it?

Thanks.
