According to the docs, the ringbuffer is not allowed to wrap in the middle of an instruction. G45 PRM, Vol 1b, p101: While the “free space” wrap may allow commands to be wrapped around the end of the Ring Buffer, the wrap should only occur between commands. Padding (with NOP) may be required to follow this restriction. Do as commanded. [Having seen bug reports where there is evidence of split commands, but apparently the GPU has continued on merrily before a bizarre and untimely death, this may or may not fix a few random hangs.] Signed-off-by:

mac Mini's have a single DDC line on the DVI connector, shared between the analog link and the digital link. So, if DDC isn't detected on GPIOE (the usual SDVO DDC link), try GPIOA (the usual VGA DDC link) when there isn't a VGA monitor connected. Signed-off-by:

It seems that on IGDNG the same swizzling setup always applys. And front buffer tiling needs to set address swizzle in display arb control too. Fix plane tricle feed setting in v1 which should be disable bit, and always setup address swizzle to let hardware care for buffer tiling in all cases. Signed-off-by:

There are several sources of unnecessary power consumption on Intel graphics systems. The first is the LVDS clock. TFTs don't suffer from persistence issues like CRTs, and so we can reduce the LVDS refresh rate when the screen is idle. It will be automatically upclocked when userspace triggers graphical activity. Beyond that, we can enable memory self refresh. This allows the memory to go into a lower power state when the graphics are idle. Finally, we can drop some clocks on the gpu itself. All of these things can be reenabled between frames when GPU activity is triggered, and so there should be no user visible graphical changes. Signed-off-by:

In the event that any one of the DAC analog outputs (R,G,B) were driven at full-scale (white video) or some analog level close to full-scale voltage, and if the video cable were then disconnected, the analog video voltage level would exceed the maximum electrical overstress limit of the native (thin-oxide) transistors thus causing a long-term reliability concern. The electrical overstress condition occurs in this particular case. This patch address the IGD EOS (electrical overstress condition) issue. When the EOS interrupt occurs, OS should disable DAC and then disable EOS, then the normal hotplug operation follows. TODO: it appears the normal unplug interrupt is missed as reported by Li Peng, need more checks here. Signed-off-by:

Currently SDVO TV only support NTSC-M format. In this patch we introduce PAL and SECAM formats available and create seting-format property at init time. When user dynamically chose preferred format by xrandr command, it will refine all modelines provided by SDVO device, then instruct SDVO device to execute. At the same time the property is added for SDVO-TV so that the SDVO-TV mode can be changed by using xrandr. https://bugs.freedesktop.org/show_bug.cgi?id=22891Signed-off-by:

For integrated TV there are 3 connector types: S-VIDEO, Composite and Component(YprPb). Those tv formats whose component flag is true should be assigned to Component connector, others are for S-VIDEO and Composite. The patch intends to find appropriate tv format for each connector. In such case it will return the correct modeline to user space. Otherwise it will return the incorrect modeline when S-video/composite is connected. Signed-off-by:

Some i915/i945 platforms have a fairly high memory latency in certain situations, so increase our constant a bit to avoid FIFO underruns. The effect should be positive on other platforms as well; we'll have a bit more insurance against a busy memory subsystem due to the extra FIFO entries. Fixes fdo bug #23368. Needed for 2.6.31.

Commit log for commit 517d3cc1 ("[libata] ata_piix: Enable parallel scan") says: This patch turns on parallel scanning for the ata_piix driver. This driver is used on most netbooks (no AHCI for cheap storage it seems). The scan is the dominating time factor in the kernel boot for these devices; with this flag it gets cut in half for the device I used for testing (eeepc). Alan took a look at the driver source and concluded that it ought to be safe to do for this driver. Alan has also checked with the hardware team. and it is all true but once we put all things together additional constraints for PATA controllers show up (some hardware registers have per-host not per-port atomicity) and we risk misprogramming the controller. I used the following test to check whether the issue is real: @@ -736,8 +736,20 @@ static void piix_set_piomode(struct ata_ (timings[pio][1] << 8); } pci_write_config_word(dev, master_port, master_data); - if (is_slave) + if (is_slave) { + if (ap->port_no == 0) { + u8 tmp = slave_data; + + while (slave_data == tmp) { + pci_read_config_byte(dev, slave_port, &tmp); + msleep(50); + } + + dev_printk(KERN_ERR, &dev->dev, "PATA parallel scan " + "race detected\n"); + } pci_write_config_byte(dev, slave_port, slave_data); + } /* Ensure the UDMA bit is off - it will be turned back on if UDMA is selected */ and it indeed triggered the error message. Lets fix all such races by adding an extra locking to ->set_piomode and ->set_dmamode methods for PATA controllers. [ Alan: would be better to take the host lock in libata-core for these cases so that we fix all the adapters in one swoop.

The lack of a proper LRU was partially worked around by taking the fence from the object containing the oldest seqno. But if there are multiple objects inactive, then they don't have seqnos and the first fence reg among them would be chosen. If you were trying to copy data between two mappings, this could result in each page fault stealing the fence from the other argument, and your application hanging. https://bugs.freedesktop.org/show_bug.cgi?id=23566 https://bugs.freedesktop.org/show_bug.cgi?id=23220 https://bugs.freedesktop.org/show_bug.cgi?id=23253 https://bugs.freedesktop.org/show_bug.cgi?id=23366 Cc: Stable Team <stable@kernel.org> Signed-off-by:
