Hi!
following is an attempted at unified patchset for the gdth driver.
They try to incorporate floating patches to gdth from:
Christoph Hellwig
Jeff Garzik
Matthew Wilcox
and Me Boaz Harrosh
They are done in the mindset of "likelihood of inducing breakage",
hence the need for testers. Christoph & Jeff please review for any
obvious easy-to-catch bugs. Also there was a massive code shifts
and rebasing I hope nothing was lost.
The differences from last set are:
- Matthews patches are first so they can go in. They
are a bit modified so please take these and not the
original. Mainly they restrain from cleanups
- Fix Christoph bug that was spotted by jeff of the misplaced
#endif. Also when compiling with out CONFIG_{ISA,EISA,PCI}
compiler would complain about unused params, functions and
so on so fixed that.
- More Aggressive fix for gdth_interrupt() and friends
Christoph pleeeeeeease review.
- Rebasing to all above. I hope I'll get the From:
right this time
Some short explanations:
[01/16] gdth: Make one abuse of scsi_cmnd less obvious - Matthew Wilcox
[02/16] gdth: Stop abusing ->done for internal commands - Matthew Wilcox
Patches from Matthew, but cleaned for future patchability.
[03/16] gdth: split out isa probing - Christoph Hellwig
[04/16] gdth: split out eisa probing - Christoph Hellwig
[05/16] gdth: split out pci probing - Christoph Hellwig
These three are from Christoph and where ACKed by
Jeff at the time. Revised by me for warning fixes when
one of the buses ISA/EISA/PCI is not defined.
[06/16] gdth: Remove 2.4.x support, in-kernel changelog - Jeff Garzik
Same but partial work was done both by Christoph and Matthew.
[07/16] gdth: kill gdth_{read,write}[bwl] wrappers - Jeff Garzik
[08/16] Reorder scsi_host_template intitializers
[09/16] gdth: Remove virt hosts - Christoph && Boaz
Here we need an executive decision! The issue is as stated by Christoph:
"The virt_ctr option allows to register a new scsi_host for each bus
on the raid controller. This non-default option makes no sense with
the current scsi code and prevents cleaning up the host registration,
so remove it."
I agree. This is just exactly the same as done buy scsi-ml scans but only
more resource consuming. Unless I'm totally missing something, perhaps it is
just a leftover from old kernels.
[10/16] gdth: clean up host private data - Christoph && Boaz
This is based on the same patch from Christoph, but taken one step
farther, by just passing the ha pointer everywhere instead of hanum.
[11/16] gdth_interrupt gdth_get_status & gdth_wait fixes - Boaz
This logically belongs to [9/16] but is separated for reviewing and
bisect-ability As it is a sensitive matter.
It is done aggressively this time around Please review!
[12/16] gdth: switch to modern scsi host registration - Christoph
Christoph what is missing from here is the remove of the deprecated
pci_find_device() call. Can I Just use pci_get_device() of the same signature
or do I need to call some other pci_ members after that?
[13/16] gdth: Remove gdth_ctr_tab[] - Boaz
I took Christoph's cleanup one step farther and got read of the statically
allocated gdth_ctr_tab[]. In it's place I use the new link-list introduced
by the [11/16] patch.
[14/16] gdth: Setup proper per-command private data - Boaz
[15/16] gdth: Move members from SCp to gdth_cmndinfo, stage 2 - Boaz
These two move me much closer to the agenda I had in all this,
which is: "gdth diss-abuse of of scsi_cmnd IO members".
With these patches I also conform to Matthew's second patch:
"gdth: Stop abusing ->done for internal commands"
[16/16] gdth: !use_sg cleanup and use of scsi accessors
And finally this one.
Boaz

Rather than having internal commands abuse scsi_done to call
gdth_scsi_done, have all the places that use to call scsi_done directly
call gdth_scsi_done, which now checks whether the command was internal,
and calls scsi_done if not.

The ->done member was being used to mark commands as being internal.
I decided to put a magic number in ->underflow instead. I believe this
to be safe as no current user of ->underflow has any of the bottom 9
bits set.

(note: this is ontop of Jeff's pci cleanup patch)
Split out isa probing into a helper of it's own. Error handling is
cleaned up, but errors are not propagated yet. Also enclose the isa
probe under the proper CONFIG_ISA symbol instead of the !IA64 hack.

From: Jeff Garzik <jeff@garzik.org>
* Remove in-source changelog. It's archived permanently in git and
various kernel archives, and changelogs should exist purely in git.
* Remove 2.4.x kernel support. It is an active obstacle to
modernizing this driver, at this point. This includes killing
gdth_kcompat.h which is 100% redundant in modern kernels.

From: Christoph Hellwig <hch@lst.de>
The virt_ctr option allows to register a new scsi_host for each bus
on the raid controller. This non-default option makes no sense with
the current scsi code and prevents cleaning up the host registration,
so remove it.

` (6 subsequent siblings)
16 siblings, 0 replies; 18+ messages in thread
From: Boaz Harrosh @ 2007-10-02 21:05 UTC (permalink / raw)
To: James Bottomley, Christoph Hellwig, Jeff Garzik, Matthew Wilcox,
linux-scsi
- Based on same patch from Christoph Hellwig <hch@lst.de>
- Get rid of all the indirection in the Scsi_Host private data and always
put the gdth_ha_str directly into it.
- Change all internal functions prototype to recieve an "gdth_ha_str *ha"
pointer directlly and kill all that redundent access to the "gdth_ctr_tab[]"
controller-table.

- gdth_get_status() returns a single device interrupt IStatus
- gdth_interrupt split to __gdth_interrupt() that receives
flags if is called from gdth_wait().
- Use dev_id passed from kernel and do not loop on all
controllers.
- gdth_wait(), get read of all global variables and call the new
__gdth_interrupt with these variables on the stack

From: Boaz Harrosh @ 2007-10-02 21:09 UTC (permalink / raw)
To: James Bottomley, Christoph Hellwig, Jeff Garzik, Matthew Wilcox,
linux-scsi
From: Christoph Hellwig <hch@lst.de>
- Use scsi_add_host and friends and track instances ourselves. And
generally modernize the driver's structure.
- TODO: Next we can remove the controller table
- TODO: Fix use of deprecated pci_find_device()

To: James Bottomley, Christoph Hellwig, Jeff Garzik, Matthew Wilcox,

- Places like Initialization and Reset that Just loop on all devices can
use the link list with the list_for_each_entry macro.
But the io_ctrl from user mode now suffers performance-wise because
code has to do a sequential search for the requested host number.
I have isolated this search in a gdth_find_ha(int hanum) member
for future enhancement if needed.

To: James Bottomley, Christoph Hellwig, Jeff Garzik, Matthew Wilcox,

- scsi_cmnd and specifically ->SCp of, where heavily abused
with internal meaning members and flags. So introduce a new
struct gdth_cmndinfo, put it on ->host_scribble and define a
gdth_cmnd_priv() accessor to retrieve it from a scsi_cmnd.
- The structure now holds two members:
internal_command - replaces the IS_GDTH_INTERNAL_CMD() croft.
sense_paddr - which was a 64-bit spanning on 2 32-bit members of SCp.
More overloaded members from SCp and scsi_cmnd will be moved in a later
patch (For easy review).
- Split up gdth_queuecommand to an additional internal_function. The later
is the one called by gdth_execute(). This will be more evident later in
the scsi accessors patch, but it also facilitates in the differentiation
between internal_command and external. And the setup of gdth_cmndinfo of
each command.

To: James Bottomley, Christoph Hellwig, Jeff Garzik, Matthew Wilcox,

- Cleanup the rest of the scsi_cmnd->SCp members and move them
to gdth_cmndinfo:
SCp.this_residual => priority
SCp.buffers_residual => timeout
SCp.Status => status and dma_dir
SCp.Message => info
SCp.have_data_in => volatile wait_for_completion
SCp.sent_command => OpCode
SCp.phase => phase
- Two more members will be naturally removed in the !use_sg cleanup
TODO: What is the meaning of gdth_cmndinfo.phase? (rhetorically)

To: James Bottomley, Christoph Hellwig, Jeff Garzik, Matthew Wilcox,
linux-scsi
gdth_execute() will issue an internal, none scsi-standard commands
onto __gdth_queuecommand(). Since it is not recommended to set
struct scsi_cmnd IO members in llds, gdth now uses internal IO
members for IO. In the case of gdth_execute() these members will be
set properly. In case the command was issued from scsi-ml
(by gdth_queuecommand) they will be set from scsi IO accessors.
* define gdth IO accessors and use them throughout the driver.
* use an sg-of-one in gdth_execute() and fix gdth_special_cmd()
accordingly.
* Clean the not use_sg code path and company
