For normal block I/O it's just raw copies over the provided protocol.

But the service exports a service by which raw SCSI commands can be
sent, for things like disk fault probing and stuff like that.  It's
not for block I/O, it's for "all the funny stuff" scsi comands are
used for outside of actual data transfers.

Then sure, use SCSI ... the ibmvscsi client originally talked to some
type of hypervisor interface too before IBM extracted it and open
sourced the server.  If actual SCSI commands are going in somewhere ...
be it a real device, a RAID firmware emulation or a hypervisor input,
then I'm happy with the driver being in SCSI.

I have no objections to VIO servers speaking SCSI ... if you want to do
that, I suggest you look at an existing example, like
drivers/scsi/ibmvscsi (the actual communication piece is very ppc
hypervisor specific, though).

However, I do strongly believe that using SCSI for devices which truly
aren't SCSI (i.e. you have to code a shim in the driver between the SCSI
commands and whatever your device speaks) is wrong ... if SCSI has
features that the generic block layer doesn't, then we need to move the
function from SCSI to block to give you access ... in theory this was
the rationale for having libata as the last "fake" SCSI driver, so we
could identify this functionality and begin to move it.

For this, it sounds like you might find nbd a more enticing
proposition ... it already is partition independent and is basically a
block to net socket exporter.

That's not gonna work, it's a totally different model.

I have a predefined protocol over hypervisor provided "channels" and
page flipping also done by the hypervisor for the bulk data transfer.
For the client side I cannot change the hypervisor nor the server
speaking on the other end.  And when I do write a server I do want
it to be able to speak to all of the existing clients.

There's SCSI command pass through as well, as I keep mentioning as
it's an important reason I don't want to go with any of the non-SCSI
solutions (other than perhaps ATA) being suggested.

It was actually meant semi-seriously in that drivers/ata sits on top of
the abstract parts of drivers/scsi which James keeps asking for someone to
get split properly off and which would sort all these out.

If your slices don't fit the PC worldview you might want to look at
dmraid and just use device mapper to handle them. It is a lot more
flexible and we could actually bin all our partition code and use this
but for back compatibility.

To allow userspace to automatically load modules, we need to hook up

This just moves the definitions of the PS3 chip_mask routines up

* [patch 01/33] Cell: Add spu shutdown method
From: Geoff Levand @ 2007-06-15 21:17 UTC (permalink / raw)
  To: paulus; +Cc: linuxppc-dev, Arnd Bergmann
In-Reply-To: <20070615204749.629571012@am.sony.com>

Add a shutdown method to spu_sysdev_class to allow proper spu resource
cleanup on system shutdown.  This is needed to support kexec on the PS3
platform.

* [patch 11/33] PS3: System-bus rework
From: Geoff Levand @ 2007-06-15 21:52 UTC (permalink / raw)
  To: paulus; +Cc: Geert Uytterhoeven, linuxppc-dev
In-Reply-To: <20070615204749.629571012@am.sony.com>

Rework the PS3 system bus to unify device support.
 - DMA region sizes must be a power of two
 - storage bus DMA updates:
  - Small fixes for the PS3 DMA core:
      o fix alignment bug
      o kill superfluous test
      o indentation
      o spelling
      o export ps3_dma_region_{create,free}()
  - ps3_dma_region_init():
      o Add `addr' and `len' parameters, so you can create a DMA region that
        does not cover all memory (use `NULL' and `0' to cover all memory).
	This is needed because there are not sufficient IOMMU resources to have
	all DMA regions cover all memory.
      o Uninline
  - Added remove and shutdown routines to all drivers.
  - Added loadable module support to all drivers.
  - Added HV calls for iopte management (needed by sound driver).

* [patch 10/33] PS3: Kexec support
From: Geoff Levand @ 2007-06-15 21:19 UTC (permalink / raw)
  To: paulus; +Cc: linuxppc-dev
In-Reply-To: <20070615204749.629571012@am.sony.com>

Fixup the core platform parts needed for kexec to work on the PS3.
 - Setup ps3_hpte_clear correctly.
 - Mask interrupts on irq removal.
 - Release all hypervisor resources.
 - Create new routine ps3_shutdown_IRQ()

Signed-off-by: Geoff Levand <geoffrey.levand@am.sony.com>
---
  o Fixed use of the ps3_kexec_cpu_down() 'secondary' arg.

* [patch 16/33] PS3: System manager re-work
From: Geoff Levand @ 2007-06-15 22:03 UTC (permalink / raw)
  To: paulus; +Cc: linuxppc-dev
In-Reply-To: <20070615204749.629571012@am.sony.com>

PS3 sys-manager updates to reflect the new PS3 unifed device support.
Fixups to the PS3 sys-manager driver to properly support sys_reboot().
 - Add varable request_tag to struct ps3_sys_manager_header.
 - Move ctrl_alt_del from PS3_SM_EVENT_POWER_RELEASED to
   PS3_SM_EVENT_POWER_PRESSED.
 - Make the PS3 sys-manager driver a loadable module.
 - Add new file sys-manager-core.c.
 - Add new struct ps3_sys_manager_ops for dynamic binding.
 - Put data sent to device on stack.
 - Add support for PS3_SM_SERVICE_ID_REQUEST_ERROR.

From: Geoff Levand @ 2007-06-15 21:18 UTC (permalink / raw)
  To: paulus; +Cc: linuxppc-dev
In-Reply-To: <20070615204749.629571012@am.sony.com>

From: Masakazu Mokuno <mokuno@sm.sony.co.jp>

Add a utility routine ps3_compare_firmware_version() to compare system
firmware versions.  Uses the existing ps3_get_firmware_version() routine.

* [patch 23/33] powerpc: Localize mmu_off
From: Geoff Levand @ 2007-06-15 22:06 UTC (permalink / raw)
  To: paulus; +Cc: linuxppc-dev
In-Reply-To: <20070615204749.629571012@am.sony.com>

This just removes the dependency __mmu_off has on the symbol
__after_prom_start.  I found the current code inconvenient when I
wanted to put some debugging code between the call to __mmu_off
and the branch to __after_prom_start.

* [patch 18/33] PS3: Frame buffer system-bus rework
From: Geoff Levand @ 2007-06-15 22:05 UTC (permalink / raw)
  To: paulus; +Cc: Geert Uytterhoeven, linuxppc-dev, linux-fbdev-devel
In-Reply-To: <20070615204749.629571012@am.sony.com>

From: Geert Uytterhoeven <Geert.Uytterhoeven@sonycom.com>

Convert the ps3fb device from a platform device to a PS3 system bus device.
Fix the remove and shutdown methods to support kexec and to make ps3fb a
loadable module.

* [patch 17/33] PS3: Rework AV settings driver
From: Geoff Levand @ 2007-06-15 22:05 UTC (permalink / raw)
  To: paulus; +Cc: Geert Uytterhoeven, linuxppc-dev
In-Reply-To: <20070615204749.629571012@am.sony.com>

Make the PS3 ps3av driver a loadable module.
  - Replace static data with kmalloc()'ed.
      o Allocate struct ps3av dynamically, as it contains data used as vuart
        receive/transmit buffers
      o Move static recv_buf from ps3av_do_pkt() to struct ps3av
  - Move ps3av_vuart_{read,write}() from drivers/ps3/ps3av_cmd.c to
    drivers/ps3/ps3av.c and make them static as they're used in that file only.
  - Make device a PS3 system-bus device.
  - Update copyright formatting.
  - Make two new routines ps3av_register_flip_ctl() and ps3av_flip_ctl() to
    support late binding of the frame buffer flip control routine.
