2010-02-25drm/nouveau: new gem pushbuf interface, bump to 0.0.16Ben Skeggs
This commit breaks the userspace interface, and requires a new libdrm for nouveau to operate again. The multiple GEM_PUSHBUF ioctls that were present in 0.0.15 for compatibility purposes are now gone, and replaced with the new ioctl which allows for multiple push buffers to be submitted (necessary for hw index buffers in the nv50 3d driver) and relocations to be applied on any buffer. A number of other ioctls (CARD_INIT, GEM_PIN, GEM_UNPIN) that were needed for userspace modesetting have also been removed.

2010-02-25drm/nv50: switch to indirect push buffer controlsBen Skeggs
PFIFO on G80 and up has a new mode where the main ring buffer is simply a ring of pointers to indirect buffers containing the actual command/data packets. In order to be able to implement index buffers in the 3D driver we need to be able to submit data-only push buffers right after the cmd packet header, which is only possible using the new command submission method. This commit doesn't make it possible to implement index buffers yet, some userspace interface changes will be required, but it does allow for testing/debugging of the hardware-side support in the meantime.

2010-02-24ahci: disable FPDMA auto-activate optimization on NVIDIA AHCIRobert Hancock
Mike Cui reported that his system with an NVIDIA MCP79 (aka MCP7A) chipset stopped working with 2.6.32. The problem appears to be that 2.6.32 now enables the FPDMA auto-activate optimization in the ahci driver. The drive works fine with this enabled on an Intel AHCI so this appears to be a chipset bug. Since MCP79 is a fairly recent NVIDIA chipset and we don't have any info on whether any other NVIDIA chipsets have this issue, disable FPDMA AA optimization on all NVIDIA AHCI controllers for now.

2010-02-24OMAP2+ clock: revise omap2_clk_{disable,enable}()Paul Walmsley
Simplify the code in the omap2_clk_disable() and omap2_clk_enable() functions, reducing levels of indentation. This makes the code easier to read. Add some additional debugging pr_debug()s here also to help others understand what is going on. Revise the omap2_clk_disable() logic so that it now attempts to disable the clock's clockdomain before recursing up the clock tree. Simultaneously, ensure that omap2_clk_enable() is called on parent clocks first, before enabling the clockdomain. This ensures that a parent clock's clockdomain is enabled before the child clock's clockdomain. These sequences should be the inverse of each other. Revise the omap2_clk_enable() logic so that it now cleans up after itself upon encountering an error. Previously, an error enabling a parent clock could have resulted in inconsistent usecounts on the enclosing clockdomain. Remove the trivial _omap2_clk_disable() and _omap2_clk_enable() static functions, and replace it with the clkops calls that they were executing. For all this to work, the clockdomain omap2_clkdm_clk_enable() and omap2_clkdm_clk_disable() code must not return an error on clockdomains without CLKSTCTRL registers; so modify those functions to simply return 0 in that case. While here, add some basic kerneldoc documentation on both functions, and get rid of some old non-CodingStyle-compliant comments that have existed since the dawn of time (at least, the OMAP clock framework's time).

2010-02-24OMAP hwmod: add hwmod class supportPaul Walmsley
Add support for categorizing and iterating over hardware IP blocks by the "class" of the IP block. The class is the type of the IP block: e.g., "timer", "timer1ms", etc. Move the OCP_SYSCONFIG/SYSSTATUS data from the struct omap_hwmod into the struct omap_hwmod_class, since it's expected to stay consistent for each class. While here, fix some comments. The hwmod_class structures in this patch were designed and proposed by Benoît Cousson <b-cousson@ti.com> and were refined in a discussion between Thara Gopinath <thara@ti.com>, Kevin Hilman <khilman@deeprootsystems.com>, and myself.

2010-02-24firewire: ohci: fix IR/IT context mask mixupStefan Richter
This bug was present in firewire-ohci since day one: The number of available isochronous receive DMA contexts was mixed up with that of available isochronous transmit DMA contexts. This is harmless on a few chips which offer the same number of contexts in both directions, but most chips nowadays implement only the standard minimum of 4 IR contexts, but 8 IT contexts. If a user attempted to run a lot of IR contexts at once, results with more than four were therefore unpredictable. I suppose the controller would simply refuse to start DMA of any unimplemented context. Signed-off-by: Stefan Richter <stefanr@s5r6.in-berlin.de>
2010-02-24firewire: ohci: add module parameter to activate quirk fixesStefan Richter
This way, we can advise users of precompiled kernel packages to test existing quirk fixes on chips which have not been listed yet, without them having to build a kernel from source. Note, to use this feature on a machine with more than one controller, steps like these are necessary: # lspci | grep 1394 # ls /sys/bus/pci/drivers/firewire_ohci/ # echo -n "0000:03:02.0" > /sys/bus/pci/drivers/firewire_ohci/unbind # echo 2 > /sys/module/firewire_ohci/parameters/quirks # echo -n "0000:03:02.0" > /sys/bus/pci/drivers/firewire_ohci/bind # echo 0 > /sys/module/firewire_ohci/parameters/quirks The parameter can also be used to switch off quirk flags that were hardwired into firewire-ohci's quirks table. Simply specify a non-zero quirks value but without any known flags, e.g. 0x100. Signed-off-by: Stefan Richter <stefanr@s5r6.in-berlin.de>
2010-02-24firewire: ohci: use an ID table for quirks detectionStefan Richter
We don't have a lot of quirks to take into account (especially since dual-buffer IR is out of the picture), but still, a table-based approach is more organized than a series of if () clauses. Signed-off-by: Stefan Richter <stefanr@s5r6.in-berlin.de>
