2006-01-09[PATCH] Update cyblafb driverKnut Petersen
This is a major update to the cyblafb framebuffer driver. Most of the stuff has been tested in the mm tree. Main advantages: ============ - vxres > xres support - ywrap and xpan support - much faster for almost all modes (e.g. 1280x1024-16bpp draws more than 41 full screens of text instead of about 25 full screens of text per second on authors Epia 5000) - module init/exit code fixed - bugs triggered by console rotation fixed - lots of minor improvements - startup modes suitable for high performance scrolling in all directions This diff also contains a lot of white space fixes. No side effects are possible, only one single graphics core is affected. Signed-off-by: Knut Petersen <Knut_Petersen@t-online.de> Signed-off-by: Linus Torvalds <torvalds@osdl.org>

2006-01-09[PATCH] sata_nv, spurious interrupts at system startup with MAXTOR 6H500F0 driveAndrew Chew
This patch works around a problem with spurious interrupts seen at boot time when a MAXTOR 6H500F0 drive is present. An ATA interrupt condition is mysteriously present at start of day. If we took too long in issuing the first command, the kernel would basically get tired of the spurious interrupts and turn the interrupt off. Issuing the first command essentially causes the interrupt condition to get acknowledged. I haven't seen this happen with any other drives. What I basically do is ack ATA status by reading it regardless of whether we're expecting to have to handle an interrupt. This clears the start-of-day anomalous interrupt condition, and keeps the kernel from disabling that interrupt due to too many spurious interrupts. Also, I fixed a bug where hotplug interrupts weren't getting acknowledged as handled in the ISR. This was not the cause of the spurious interrupts, but it's the right thing to do anyway.

Disable TX status deferral (EMACx_MR[MWSW=001]) in half-duplex mode. I have two reports when EMAC stops transmitting when connected to a hub. TX ring debug printouts show complete mess when this happens, probably hardware collision handling doesn't work quite well in this mode.

2006-01-09[PATCH] sk98lin: routine called from probe marked __initStephen Hemminger
Sk98lin driver has a routine marked __init that is called from the probe code. If using pci hotplug, this could be called after the initialization so it needs to be marked __devinit. So if you hot added a sk98lin board, the kernel would crash. I don't have hot plug hardware to actually try this feat. Also, there are two routines, only called from SkGeBoardInit that can be marked __devinit. Signed-off-by: Stephen Hemminger <shemminger@osdl.org> Signed-off-by: Jeff Garzik <jgarzik@pobox.com>

2006-01-09[PATCH] 3/5 powerpc: Add platform functions interpreterBenjamin Herrenschmidt
This is the platform function interpreter itself along with the backends for UniN/U3/U4, mac-io, GPIOs and i2c. It adds the ability to execute those do-platform-* scripts in the device-tree (at least for most devices for which a backend is provided). This should replace the clock spreading hacks properly. It might also have an impact on all sort of machines since some of the scripts marked "at init" will now be executed on boot (or some other on sleep/wakeup), those will possibly do things that the kernel didn't do at all, like setting some values into some i2c devices (changing thermal sensor calibration or conversion rate) etc... Thus regression testing is MUCH welcome. Also loook for errors in dmesg. That's also why I've left rather verbose debugging enabled in this version of the patch. (I do expect some Windtunnel G4s to show some errors as they have an i2c clock chip on the PMU bus that uses some primitives that the i2c backend doesn't implement yet. I really need users that have one of those machine to come back to me so we can get that done right, though the errors themselves should be harmless, I suspect the machine might not run at full speed).

2006-01-09[PATCH] 2/5 powerpc: Rework PowerMac i2c part 2Benjamin Herrenschmidt
This is the continuation of the previous patch. This one removes the old PowerMac i2c drivers (i2c-keywest and i2c-pmac-smu) and replaces them both with a single stub driver that uses the new PowerMac low i2c layer. Now that i2c-keywest is gone, the low-i2c code is extended to support interrupt driver transfers. All i2c busses now appear as platform devices. Compatibility with existing drivers should be maintained as the i2c bus names have been kept identical, except for the SMU bus but in that later case, all users has been fixed. With that patch added, matching a device node to an i2c_adapter becomes trivial. Signed-off-by: Benjamin Herrenschmidt <benh@kernel.crashing.org> Signed-off-by: Paul Mackerras <paulus@samba.org>
2006-01-09[PATCH] 1/5 powerpc: Rework PowerMac i2c part 1Benjamin Herrenschmidt
This is the first part of a rework of the PowerMac i2c code. It completely reworks the "low_i2c" layer. It is now more flexible, supports KeyWest, SMU and PMU i2c busses, and provides functions to match device nodes to i2c busses and adapters. This patch also extends & fix some bugs in the SMU driver related to i2c support and removes the clock spreading hacks from the pmac feature code rather than adapting them to the new API since they'll be replaced by the platform function code completely in patch 3/5 Signed-off-by: Benjamin Herrenschmidt <benh@kernel.crashing.org> Signed-off-by: Paul Mackerras <paulus@samba.org>

2006-01-08[PATCH] /dev/mem: validate mmap requestsBjorn Helgaas
Add a hook so architectures can validate /dev/mem mmap requests. This is analogous to validation we already perform in the read/write paths. The identity mapping scheme used on ia64 requires that each 16MB or 64MB granule be accessed with exactly one attribute (write-back or uncacheable). This avoids "attribute aliasing", which can cause a machine check. Sample problem scenario: - Machine supports VGA, so it has uncacheable (UC) MMIO at 640K-768K - efi_memmap_init() discards any write-back (WB) memory in the first granule - Application (e.g., "hwinfo") mmaps /dev/mem, offset 0 - hwinfo receives UC mapping (the default, since memmap says "no WB here") - Machine check abort (on chipsets that don't support UC access to WB memory, e.g., sx1000) In the scenario above, the only choices are - Use WB for hwinfo mmap. Can't do this because it causes attribute aliasing with the UC mapping for the VGA MMIO space. - Use UC for hwinfo mmap. Can't do this because the chipset may not support UC for that region. - Disallow the hwinfo mmap with -EINVAL. That's what this patch does.
