| | | | | | | | | | | | | Remove ugly all-over-the-code casts of ctl_addr to 9060 space. Add an union to the cyclades_card structure, which contains a pointer to both 9050 and 9060 spaces. The 9050 space layout is unknown, so let it still as a void __iomem pointer.

* tty: synclink_gt add receive pio modePaul Fulghum2009-06-111-9/+68
| | | | | | | | | | | | Add receive programmed IO mode to reduce receive latency when using low data rates. The receive FIFO trigger level of 128 bytes used in DMA mode creates excessive latency when operating at low data rates. PIO mode is selected when user application requests data in blocks of less than 128 bytes.

* char: mxser, fix ISA board lookupPeter Botha2009-06-101-1/+1
| | | | | | | | | | | | | | | | | There's a bug in the mxser kernel module that still appears in the 2.6.29.4 kernel. mxser_get_ISA_conf takes a ioaddress as its first argument, by passing the not of the ioaddr, you're effectively passing 0 which means it won't be able to talk to an ISA card. I have tested this, and removing the ! fixes the problem.

( original thread at http://lkml.org/lkml/2009/6/8/192 ) Problem is this driver tells that NIC frames up to 16383 bytes can be received but provides skb to rx ring allocated with smaller sizes (1536 bytes in case standard 1500 bytes MTU is used) When a frame larger than what was allocated by driver is received, dma transfert can occurs past the end of buffer and corrupt kernel memory. Fix is to tell to NIC what is the maximum size a frame can be. This bug is very old, (before git introduction, linux-2.6.10), and should be backported to stable versions.

| * | md/raid5: fix bug in reshape code when chunk_size decreases.NeilBrown2009-06-091-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Now that we support changing the chunksize, we calculate "reshape_sectors" to be the max of number of sectors in old and new chunk size. However there is one please where we still use 'chunksize' rather than 'reshape_sectors'. This causes a reshape that reduces the size of chunks to freeze. Signed-off-by: NeilBrown <neilb@suse.de>
| * | md/raid5 - avoid deadlocks in get_active_stripe during reshapeNeilBrown2009-06-091-11/+11

This is used to achieve a stable state before making internal changes. Currently this quiescing applies equally to normal IO, resync IO, and reshape IO. However there is a problem with applying it to reshape IO. Reshape can have multiple 'stripe_heads' that must be active together. If the quiesce come between allocating the first and the last of such a collection, then we deadlock, as the last will not be allocated until the quiesce is lifted, the quiesce will not be lifted until the first (which has been allocated) gets used, and that first cannot be used until the last is allocated. It is not necessary to inhibit reshape IO when a quiesce is requested. Those places in the code that require a full quiesce will ensure the reshape thread is not running at all. So allow reshape requests to get access to new stripe_heads without being blocked by a 'quiesce'. This only affects in-place reshapes (i.e. where the array does not grow or shrink) and these are only newly supported. So this patch is not needed in earlier kernels.

It is a suggestion as to what number of raid_disks is desired. conf->raid_disks can only be changed by the raid5 module with suitable locks in place. It is a statement as to the current number of raid_disks. There are two places where the latter should be used, but the former is used. This can lead to a crash when reshaping an array.

However if the system was busy, or debugging was enabled, or a udelay(100) was inserted before the second SWITCH command in the core code, then the timing was so that the card started to work. With some unusual block sizes, the data FIFO status doesn't indicate a "empty" state right away when the data transfer is done. Queuing another data transfer in that condition results in a transfer timeout. The empty FIFO bit eventually get set by itself in less than 50 usecs when it is not set right away. So let's just poll for that bit before configuring the controller with a new data transfer. Signed-off-by: Nicolas Pitre <nico@marvell.com> Signed-off-by: Pierre Ossman <pierre@ossman.eu>

Fortunately, HP recently released BIOS updates for all machines to fix the issue. Detect old BIOSen, warn the user to update BIOS on boot and suspend attempts and fail suspend. Kudos to all the bug reporters.

With async probing, it's not waiting until discovery is finished before deciding it has no devices and trying the detach leading to this warning: ata1: PATA max PIO4 cmd 0x1f0 ctl 0x3f6 irq 14 ------------[ cut here ]------------ WARNING: at drivers/ata/libata-core.c:6222 ata_host_detach+0x75/0x90() Modules linked in: Pid: 1, comm: swapper Not tainted 2.6.30-rc7 #1 Call Trace: [<c01fbb05>] ? ata_host_detach+0x75/0x90 [<c01fbb05>] ? ata_host_detach+0x75/0x90 [<c01139b5>] ? warn_slowpath_common+0x45/0x80 [<c01139fa>] ? warn_slowpath_null+0xa/0x10 [<c01fbb05>] ? ata_host_detach+0x75/0x90 [<c02f40e0>] ? legacy_init+0x44e/0x87f [<c02f3c92>] ? legacy_init+0x0/0x87f [<c0101021>] ? _stext+0x21/0x140 [<c01890ff>] ? proc_register+0x2f/0x190 [<c018938c>] ? create_proc_entry+0x5c/0xc0 [<c0135ebe>] ? register_irq_proc+0x6e/0x90 [<c02e6484>] ? kernel_init+0x6e/0xbf [<c02e6416>] ? kernel_init+0x0/0xbf [<c01031d7>] ? kernel_thread_helper+0x7/0x10 ---[ end trace ef1ee36e873ae3a0 ]--- Because it detaches before the probe is complete. One way to fix it would be to put an async_synchronize_full() before looking for devices, which this patch does. A better way might be to separate libata into its own domain and only wait for that.
