* [ARM] pxa: Add PXA3 standby code hooked into the IRQ wake schemeRussell King2008-01-26
| | | | | | | | | | | | | | | | Wakeup sources on PXA3 are enabled at two levels. First, the MFP configuration has to be set to enable which edges a specific pin will trigger a wakeup. The pin also has to be routed to a functional unit. Lastly, the functional unit must be enabled as a wakeup source in the appropriate AD*ER registers (AD2D0ER for standby resume.) This doesn't fit well with the IRQ wake scheme - we currently do a best effort conversion from IRQ numbers to functional unit wake enable bits. For instance, there's several USB client related enable bits but there's no corresponding IRQs to determine which you'd want. Conversely, there's a single enable bit covering several functional units. Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
* [ARM] pxa: make MFP configuration processor independenteric miao2008-01-26
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | There are two reasons for making the MFP configuration to be processor independent, i.e. removing the relationship of configuration bits with actual MFPR register settings: 1. power management sometimes requires the MFP to be configured differently when in run mode or in low power mode 2. for future integration of pxa{25x,27x} GPIO configurations The modifications include: 1. introducing of processor independent MFP configuration bits, as defined in [include/asm-arm/arch-pxa/mfp.h]: bit 0.. 9 - MFP Pin Number (1024 Pins Maximum) bit 10..12 - Alternate Function Selection bit 13..15 - Drive Strength bit 16..18 - Low Power Mode State bit 19..20 - Low Power Mode Edge Detection bit 21..22 - Run Mode Pull State and so on, 2. moving the processor dependent code from mfp.h into mfp-pxa3xx.h 3. cleaning up of the MFPR bit definitions 4. mapping of processor independent MFP configuration into processor specific MFPR register settings is now totally encapsulated within pxa3xx_mfp_config() 5. using of "unsigned long" instead of invented type of "mfp_cfg_t" according to Documentation/CodingStyle Chapter 5, usage of this in platform code will be slowly removed in later patches Signed-off-by: eric miao <eric.miao@marvell.com> Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>

| | | | | | | | | | | | FFUART and friends are already defined as __REG(x) in pxa-regs.h. Instead of redefining them here, we can just provide the __REG macro. Including asm/arch/hardware.h is not an option because this physical addresses are needed here. This is a fix for the compiler warnings generated by 4663/1.

| * [SCSI] use dynamically allocated sense bufferFUJITA Tomonori2008-01-23
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This removes static array sense_buffer in scsi_cmnd and uses dynamically allocated sense_buffer (with GFP_DMA). The reason for doing this is that some architectures need cacheline aligned buffer for DMA: http://lkml.org/lkml/2007/11/19/2 The problems are that scsi_eh_prep_cmnd puts scsi_cmnd::sense_buffer to sglist and some LLDs directly DMA to scsi_cmnd::sense_buffer. It's necessary to DMA to scsi_cmnd::sense_buffer safely. This patch solves these issues. __scsi_get_command allocates sense_buffer via kmem_cache_alloc and attaches it to a scsi_cmnd so everything just work as before.

| * [SCSI] block: Introduce new blk_queue_update_dma_alignment interfaceJames Bottomley2008-01-11
| | | | | | | | | | | | | | | | | | | | | | | | | | | | The purpose of this is to allow stacked alignment settings, with the ultimate queue alignment being set to the largest alignment requirement in the stack. The reason for this is so that the SCSI mid-layer can relax the default alignment requirements (which are basically causing a lot of superfluous copying to go on in the SG_IO interface) while allowing transports, devices or HBAs to add stricter limits if they need them.

| * [SCSI] libiscsi: fix nop handlingMike Christie2008-01-11
| | | | | | | | | | | | | | | | | | | | | | | | During root boot and shutdown the target could send us nops.

| | | | | | | | | | | | | | | | | | | | | | | | | | We were using the device delete sysfs file to remove each device then logout. Now in 2.6.21 this will not work because the sysfs delete file returns immediately and does not wait for the device removal to complete. This causes a hang if a cache sync is needed during shutdown. Before .21, that approach had other problems, so this patch fixes the shutdown code so that we remove the target and unbind the session before logging out and shut down the session Signed-off-by: Mike Christie <michaelc@cs.wisc.edu> Signed-off-by: James Bottomley <James.Bottomley@HansenPartnership.com>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | iscsi_pool_init simplified iscsi_pool_init currently has a lot of duplicate kfree() calls it does when some allocation fails. This patch simplifies the code a little by using iscsi_pool_free to tear down the pool in case of an error. iscsi_pool_init also returns a copy of the item array to the caller. Not all callers use this array, so we make it optional. Instead of allocating a second array and return that, allocate just one array, of twice the size. Update users of iscsi_pool_{init,free} This patch drops the (now useless) second argument to iscsi_pool_free, and updates all callers. It also removes the ctask->r2ts array, which was never used anyway. Since the items argument to iscsi_pool_init is now optional, we can pass NULL instead.

Here I add a hdr_max field pertaining to that storage, and an hdr_len that accumulates the current use of the pdu-header. - Add an iscsi_next_hdr() inline which returns the next free space to write new Header at. Also iscsi_next_hdr() is used to retrieve the address at which to write the header-digest. - Add iscsi_add_hdr(length). What the user do is calls iscsi_next_hdr() for address of the new header, than calls iscsi_add_hdr(length) with the size of the new header. iscsi_add_hdr() will check if space is available and update to the new size. length must be padded according to standard. - Add 2 padding inline helpers thanks to Olaf. Current patch does not use them but Following patches will. Also moved definition of ISCSI_PAD_LEN to iscsi_proto.h which had PAD_WORD_LEN that was never used anywhere. - Let iscsi_prep_scsi_cmd_pdu() signal an Error return since now it is possible that it will fail. - I was tired of yet again writing a "this is a digest" comment next to sizeof(__u32) so I defined a new ISCSI_DIGEST_SIZE. Now I don't need any comments. Changed all places that used sizeof(__u32) or "4" in connection to a digest. iscsi_tcp specific code - At struct iscsi_tcp_cmd_task allocate maximum space allowed in standard for all headers following the iscsi_cmd header. and mark it so in iscsi_tcp_session_create() - At iscsi_send_cmd_hdr() retrieve the correct headers size and write header digest at iscsi_next_hdr().

| * [SCSI] move single_lun flag from scsi_device to scsi_targetTony Battersby2008-01-11
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Some SCSI tape medium changers that need the BLIST_SINGLELUN flag have the medium changer at one LUN and the tape drive at a different LUN. The inquiry string of the tape drive may be different from that of the medium changer. In order for single_lun to be effective, every scsi_device under a given scsi_target must have it set. This means that there needs to be a blacklist entry for BOTH the medium changer AND the tape drive, which is impractical because some medium changers may be paired with a variety of different tape drive models. It makes more sense to put the single_lun flag in scsi_target instead of scsi_device, which causes every device at a given target ID to inherit the single_lun flag from one LUN. This makes it possible to blacklist just the medium changer and not the tape drive.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Factor out ata_pci_activate_sff_host() from ata_pci_one(). This does about the same thing as ata_host_activate() but needs to be separate because SFF controllers use different and multiple IRQs in legacy mode. This will be used to make SFF LLD initialization more flexible. Signed-off-by: Tejun Heo <htejun@gmail.com> Signed-off-by: Jeff Garzik <jeff@garzik.org>

| * | | libata: make qc->nbytes include extra buffersTejun Heo2008-01-23
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | qc->nbytes didn't use to include extra buffers setup by libata core layer and my be odd. This patch makes qc->nbytes include any extra buffers setup by libata core layer and guaranteed to be aligned on 4 byte boundary. This value is to be used to program the host controller. As this represents the actual length of buffer available to the controller and the controller must be able to deal with short transfers for ATAPI commands which can transfer variable length, this shouldn't break any controllers while making problems like rounding-down and controllers choking up on odd transfer bytes much less likely. The unmodified value is stored in new field qc->raw_nbytes. Signed-off-by: Tejun Heo <htejun@gmail.com> Signed-off-by: Jeff Garzik <jeff@garzik.org>
| * | | libata: convert to chained sgTejun Heo2008-01-23

Now that sg can be chained, padding can be handled using standard sg ops. Convert to chained sg. * s/qc->__sg/qc->sg/ * s/qc->pad_sgent/qc->extra_sg[]/. Because chaining consumes one sg entry. There need to be two extra sg entries. The renaming is also for future addition of other extra sg entries. * Padding setup is moved into ata_sg_setup_extra() which is organized in a way that future addition of other extra sg entries is easy. * qc->orig_n_elem is unused and removed. * qc->n_elem now contains the number of sg entries that LLDs should map. qc->mapped_n_elem is added to carry the original number of mapped sgs for unmapping. * The last sg of the original sg list is used to chain to extra sg list. The original last sg is pointed to by qc->last_sg and the content is stored in qc->saved_last_sg. It's restored during ata_sg_clean(). * All sg walking code has been updated. Unnecessary assertions and checks for conditions the core layer already guarantees are removed.

Kill non-sg interface. * ATA_QCFLAG_SINGLE and ATA_QCFLAG_SG are removed. ATA_QCFLAG_DMAMAP is used instead. (this way no LLD change is necessary) * qc->buf_virt is removed. * ata_sg_init_one() and ata_sg_setup_one() are removed.
