* [PATCH] md: assorted md and raid1 one-linersNeilBrown2006-12-10
| | | | | | | | | | | | | | | | | | | | | | | | Fix few bugs that meant that: - superblocks weren't alway written at exactly the right time (this could show up if the array was not written to - writting to the array causes lots of superblock updates and so hides these errors). - restarting device recovery after a clean shutdown (version-1 metadata only) didn't work as intended (or at all). 1/ Ensure superblock is updated when a new device is added. 2/ Remove an inappropriate test on MD_RECOVERY_SYNC in md_do_sync. The body of this if takes one of two branches depending on whether MD_RECOVERY_SYNC is set, so testing it in the clause of the if is wrong. 3/ Flag superblock for updating after a resync/recovery finishes. 4/ If we find the neeed to restart a recovery in the middle (version-1 metadata only) make sure a full recovery (not just as guided by bitmaps) does get done.

* [PATCH] md: return a non-zero error to bi_end_io as appropriate in raid5NeilBrown2006-12-10
| | | | | | | | | | Currently raid5 depends on clearing the BIO_UPTODATE flag to signal an error to higher levels. While this should be sufficient, it is safer to explicitly set the error code as well - less room for confusion.

* [PATCH] md: remove some old ifdefed-out code from raid5.cNeilBrown2006-12-10
| | | | | | | | | | | | | There are some vestiges of old code that was used for bypassing the stripe cache on reads in raid5.c. This was never updated after the change from buffer_heads to bios, but was left as a reminder. That functionality has nowe been implemented in a completely different way, so the old code can go.

* [PATCH] md: fix innocuous bug in raid6 stripe_to_pdidxNeilBrown2006-12-10
| | | | | | | | | | | | | | | | | | | | stripe_to_pdidx finds the index of the parity disk for a given stripe. It assumes raid5 in that it uses "disks-1" to determine the number of data disks. This is incorrect for raid6 but fortunately the two usages cancel each other out. The only way that 'data_disks' affects the calculation of pd_idx in raid5_compute_sector is when it is divided into the sector number. But as that sector number is calculated by multiplying in the wrong value of 'data_disks' the division produces the right value. So it is innocuous but needs to be fixed. Also change the calculation of raid_disks in compute_blocknr to make it more obviously correct (it seems at first to always use disks-1 too).

* [PATCH] md: allow reads that have bypassed the cache to be retried on failureRaz Ben-Jehuda(caro)2006-12-10
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | If a bypass-the-cache read fails, we simply try again through the cache. If it fails again it will trigger normal recovery precedures. update 1: From: NeilBrown <neilb@suse.de> 1/ chunk_aligned_read and retry_aligned_read assume that data_disks == raid_disks - 1 which is not true for raid6. So when an aligned read request bypasses the cache, we can get the wrong data. 2/ The cloned bio is being used-after-free in raid5_align_endio (to test BIO_UPTODATE). 3/ We forgot to add rdev->data_offset when submitting a bio for aligned-read 4/ clone_bio calls blk_recount_segments and then we change bi_bdev, so we need to invalidate the segment counts. 5/ We don't de-reference the rdev when the read completes. This means we need to record the rdev to so it is still available in the end_io routine. Fortunately bi_next in the original bio is unused at this point so we can stuff it in there. 6/ We leak a cloned bio if the target rdev is not usable. From: NeilBrown <neilb@suse.de> update 2: 1/ When aligned requests fail (read error) they need to be retried via the normal method (stripe cache). As we cannot be sure that we can process a single read in one go (we may not be able to allocate all the stripes needed) we store a bio-being-retried and a list of bioes-that-still-need-to-be-retried. When find a bio that needs to be retried, we should add it to the list, not to single-bio... 2/ We were never incrementing 'scnt' when resubmitting failed aligned requests.

| | | | | | | | | | | | | | | | The ESB2 appears to emit spurious DMA interrupts when configured for native mode and handling ATAPI devices. Stratus were able to pin this bug down and produce a patch. This is a rework which applies the fixup only to the ESB2 (for now). We can apply it to other chips later if the same problem is found.

* [PATCH] pdc202xx_new: fix PLL/timing issuesSergei Shtylyov2006-12-10
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Fix the CRC errors in the higher UltraDMA modes with the Promise PDC20268 and newer chips that always occur on non-x86 machines and when there are more than 2 adapters on x86 machines. Fix the overclocking issue for PDC20269 and newer chips that occurs when an UltraDMA/133 capable drive is connected. Here's the summary of changes: - add code to detect the PLL input clock detection and setup it output clock, remove the PowerMac hacks; - replace the macros accessing the indexed regiters with functions, switch to using them where appropriate, gather the PIO/MWDMA/UDMA timings into tables; - rewrite the speedproc() handler to set the drive's transfer mode first, and then override the timing registers set by hardware on UltraDMA/133 chips; - use better criterion for determining higher UltraDMA modes, and add comment concerning the doubtful value of the code enabling IORDY/prefetch; - replace the stupid 'pdcnew_new_' prefixes with mere 'pdcnew_'; - get rid of unneded spaces, parens and type casts, clean up some printk's, add some new lines here and there... This work is loosely based on these former patches by Albert Lee: [1] http://marc.theaimsgroup.com/?l=linux-ide&m=110992442032300 [2] http://marc.theaimsgroup.com/?l=linux-ide&m=110992457729382 [3] http://marc.theaimsgroup.com/?l=linux-ide&m=110992474205555 [4] http://marc.theaimsgroup.com/?l=linux-ide&m=111019224802939 Some PLL clock detection code was backported from his pata_pdc2027x driver... This code has been successfully tested by me on PDC2026[89] chips. I tried to keep this rework as several patches but it made no sense: [2] was largely a modification of the non-working timing override code, [3] by itself extended the overclocking issue to the case of non-UltraDMA/133 drives, and finally, the cleanup patch based on [1] ended up rejected...

* [PATCH] spi: stabilize PIO mode transfers on PXA2xx systemsStephen Street2006-12-10
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Stabilize PIO mode transfers against a range of word sizes and FIFO thresholds and fixes word size setup/override issues. 1) 16 and 32 bit DMA/PIO transfers broken due to timing differences. 2) Potential for bad transfer counts due to transfer size assumptions. 3) Setup function broken is multiple ways. 4) Per transfer bit_per_word changes break DMA setup in pump_tranfers. 5) False positive timeout are not errors. 6) Changes in pxa2xx_spi_chip not effective in calls to setup. 7) Timeout scaling wrong for PXA255 NSSP. 8) Driver leaks memory while busy during unloading. Known issues: SPI_CS_HIGH and SPI_LSB_FIRST settings in struct spi_device are not handled. Testing: This patch has been test against the "random length, random bits/word, random data (verified on loopback) and stepped baud rate by octaves (3.6MHz to 115kHz)" test. It is robust in PIO mode, using any combination of tx and rx thresholds, and also in DMA mode (which internally computes the thresholds). Much thanks to Ned Forrester for exhaustive reviews, fixes and testing. The driver is substantially better for his efforts.

* [PATCH] read_zero_pagealigned() locking fixHugh Dickins2006-12-10
| | | | | | | | | | | | | | | | | | | | | | | | | Ramiro Voicu hits the BUG_ON(!pte_none(*pte)) in zeromap_pte_range: kernel bugzilla 7645. Right: read_zero_pagealigned uses down_read of mmap_sem, but another thread's racing read of /dev/zero, or a normal fault, can easily set that pte again, in between zap_page_range and zeromap_page_range getting there. It's been wrong ever since 2.4.3. The simple fix is to use down_write instead, but that would serialize reads of /dev/zero more than at present: perhaps some app would be badly affected. So instead let zeromap_page_range return the error instead of BUG_ON, and read_zero_pagealigned break to the slower clear_user loop in that case - there's no need to optimize for it. Use -EEXIST for when a pte is found: BUG_ON in mmap_zero (the other user of zeromap_page_range), though it really isn't interesting there. And since mmap_zero wants -EAGAIN for out-of-memory, the zeromaps better return that than -ENOMEM.

| | | | | | | | | | | | | | | | This makes it easier for userspace to know when it needs to allocate an ID. Also free drawable information memory when it's no longer needed. Signed-off-by: Dave Airlie <airlied@linux.ie>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | Actually make the existing ioctls for adding and removing drawables do something useful, and add another ioctl for the X server to update drawable information. The only kind of drawable information tracked so far is cliprects. Only reallocate cliprect memory if the number of cliprects changes. Also improve diagnostic output. hook up drm ioctl update draw export drm_get_drawable_info symbol Signed-off-by: Dave Airlie <airlied@linux.ie>

| | | | | | | | | | | | | | | | When the vertical blank interrupt is enabled for both pipes, pipe A is considered primary and pipe B secondary. When it's only enabled for one pipe, it's always considered primary for backwards compatibility. Signed-off-by: Dave Airlie <airlied@linux.ie>
