* [PATCH] Make printk work for really early debuggingMichael Ellerman2006-06-25
| | | | | | | | | | | | | | | | | | | | | | | | | Currently printk is no use for early debugging because it refuses to actually print anything to the console unless cpu_online(smp_processor_id()) is true. The stated explanation is that console drivers may require per-cpu resources, or otherwise barf, because the system is not yet setup correctly. Fair enough. However some console drivers might be quite happy running early during boot, in fact we have one, and so it'd be nice if printk understood that. So I added a flag (which I would have called CON_BOOT, but that's taken) called CON_ANYTIME, which indicates that a console is happy to be called anytime, even if the cpu is not yet online. Tested on a Power 5 machine, with both a CON_ANYTIME driver and a bogus console driver that BUG()s if called while offline. No problems AFAICT. Built for i386 UP & SMP.

* [PATCH] ufs: make fsck -f happyEvgeniy Dushistov2006-06-25
| | | | | | | | | | | | | | | | | | | | | | ufs super block contains some statistic about file systems, like amount of directories, free blocks, inodes and so on. UFS1 hold this information in one location and uses 32bit integers for such information, UFS2 hold statistic in another location and uses 64bit integers. There is transition variant, if UFS1 has type 44BSD and flags field in super block has some special value this mean that we work with statistic like UFS2 does. and this also means that nobody care about old(UFS1) statistic. So if start fsck against such file system, after usage linux ufs driver, it found error: at now only UFS1 like statistic is updated. This patch should fix this. Also it contains some minor cleanup: CodingSytle and remove unused variables.

* [PATCH] ufs: one way to access super blockEvgeniy Dushistov2006-06-25
| | | | | | | | | | | | | | | | | | | | | | | | | Super block of UFS usually has size >512, because of fragment size may be 512, this cause some problems. Currently, there are two methods to work with ufs super block: 1) split structure which describes ufs super blocks into structures with size <=512 2) use one structure which describes ufs super block, and hope that array of "buffer_head" which holds "super block", has such construction: bh[n]->b_data + bh[n]->b_size == bh[n + 1]->b_data The second variant may cause some problems in the future, and usage of two variants cause unnecessary code duplication. This patch remove the second variant. Also patch contains some CodingStyle fixes.

* [PATCH] ufs: change block number on the flyEvgeniy Dushistov2006-06-25
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | First of all some necessary notes about UFS by it self: To avoid waste of disk space the tail of file consists not from blocks (which is ordinary big enough, 16K usually), it consists from fragments(which is ordinary 2K). When file is growing its tail occupy 1 fragment, 2 fragments... At some stage decision to allocate whole block is made and all fragments are moved to one block. How this situation was handled before: ufs_prepare_write ->block_prepare_write ->ufs_getfrag_block ->... ->ufs_new_fragments: bh = sb_bread bh->b_blocknr = result + i; mark_buffer_dirty (bh); This is wrong solution, because: - it didn't take into consideration that there is another cache: "inode page cache" - because of sb_getblk uses not b_blocknr, (it uses page->index) to find certain block, this breaks sb_getblk. How this situation is handled now: we go though all "page inode cache", if there are no such page in cache we load it into cache, and change b_blocknr.

* [PATCH] page migration: Support a vma migration functionChristoph Lameter2006-06-25
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Hooks for calling vma specific migration functions With this patch a vma may define a vma->vm_ops->migrate function. That function may perform page migration on its own (some vmas may not contain page structs and therefore cannot be handled by regular page migration. Pages in a vma may require special preparatory treatment before migration is possible etc) . Only mmap_sem is held when the migration function is called. The migrate() function gets passed two sets of nodemasks describing the source and the target of the migration. The flags parameter either contains MPOL_MF_MOVE which means that only pages used exclusively by the specified mm should be moved or MPOL_MF_MOVE_ALL which means that pages shared with other processes should also be moved. The migration function returns 0 on success or an error condition. An error condition will prevent regular page migration from occurring. On its own this patch cannot be included since there are no users for this functionality. But it seems that the uncached allocator will need this functionality at some point.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Currently, the only per-dev EH action is REVALIDATE. EH used to exploit ehi->dev to do selective revalidation on a ATA bus. However, this is a bit hacky and makes it impossible to request selective revalidation from outside of EH or add another per-dev EH action. This patch adds per-dev EH action mask eh_info->dev_action[] and update EH to use this field for REVALIDATE. Note that per-dev actions can still be specified at port-level and it has the same effect of specifying the action for all devices on the port.

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.

Extract PHY waiting code from sata_phy_resume() and extend it to include SStatus debouncing. Note that sata_phy_debounce() is superset of what used to be done inside sata_phy_resume(). Three default debounce timing parameters are defined to be used by hot/boot plug. As resume failure during probing will be properly handled as errors, timeout doesn't have to be long as before. probeinit() uses the same timeout to retain the original behavior.

| * | | | [PATCH] libata: implement ata_eh_wait()Tejun Heo2006-05-31
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Implement ata_eh_wait(). On return from this function, it's guaranteed that the EH which was pending or in progress when the function was called is complete - including the tailing part of SCSI EH. This will be used by hotplug and others to synchronize with EH. Signed-off-by: Tejun Heo <htejun@gmail.com>

| * | | | [PATCH] libata: Remove obsolete flagAlan Cox2006-05-24
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | ATA_FLAG_IRQ_MASK was added when I did the original data transfer with IRQ masked bits for PIO. It has since been replaced by ->pio_data_xfer methods so should be removed so nobody uses it by mistake thinking it still works.

| * | | | [PATCH] PATCH: libata. Add ->data_xfer methodAlan Cox2006-05-24
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | We need to pass the device in order to do per device checks such as 32bit I/O enables. With the changes to include dev->ap we now don't have to add parameters however just clean them up. Also add data_xfer methods to the existing drivers except ata_piix (which is in the other block of patches). If you reject the piix one just add a data_xfer to it...

Changes: - Better mapping in ac_err_mask() - In HSM_ST_FIRST ans HSM_ST state, check ATA_ERR|ATA_DF and map it to AC_ERR_DEV instead of AC_ERR_HSM. - In HSM_ST_FIRST and HSM_ST state, map DRQ=1 ERR=1 to AC_ERR_HSM. - For PIO data in and DRQ=1 ERR=1, add check after the junk data block is read.
