2010-01-07drm: remove address mask param for drm_pci_alloc()Zhenyu Wang5-13/+13
drm_pci_alloc() has input of address mask for setting pci dma mask on the device, which should be properly setup by drm driver. And leave it as a param for drm_pci_alloc() would cause confusion or mistake would corrupt the correct dma mask setting, as seen on intel hw which set wrong dma mask for hw status page. So remove it from drm_pci_alloc() function. Signed-off-by: Zhenyu Wang <zhenyuw@linux.intel.com> Signed-off-by: Dave Airlie <airlied@redhat.com>

2010-01-06drm/i915: Add DP dpll limit on ironlake and use existing DPLL search functionZhao Yakui1-68/+48
For some clocks, the old Ironlake DPLL calculator wold give m/n/p combinations that didn't match the spreadsheet of what HW validation tests. Instead, use the G4X DPLL calculator, which does a better job at it. So we use the intel_g4x_find_best_pll to calculate the DPLL for CRT/HDMI/LVDS on ironlake. At the same time to consider the dpll setting for display port, we add the display port DPLL limit on ironlake, which will directly use the function of intel_find_pll_ironlake_dp to get the corresponding dpll setting.

2010-01-06drm/i915: remove render reclock supportJesse Barnes1-130/+2
This code generally fails to adjust the render clock, and when it does, it conflicts with some other register settings and can cause problems. So remove this code altogether. I'm reworking it now to do the right thing, but the only bit it will share is the VBT check for whether reclocking is supported, so I'm leaving that bit. Reverts most of 652c393a3368af84359da37c45afc35a91144960 ("add dynamic clock frequency control"), though for many the regressions showed up in the later 181a5336d6cc836f05507410d66988c483ad0154 ("Fix render reclock availability detection").

2010-01-06drm/i915: execbuf2 supportJesse Barnes4-78/+219
This patch adds a new execbuf ioctl, execbuf2, for use by clients that want to control fence register allocation more finely. The buffer passed in to the new ioctl includes a new relocation type to indicate whether a given object needs a fence register assigned for the command buffer in question. Compatibility with the existing execbuf ioctl is implemented in terms of the new code, preserving the assumption that fence registers are required for pre-965 rendering commands.

During a manual scan, a user can send command to a nonexistent lun, precisely at the point of max_lun. Normally it's possible (but not required) that the firmware has the knowledge that it is an invalid lun. In the particular case when max_lun is 256, however, the nonexistent lun 256 will be confused with lun 0, because the lun member in a request message is only u8, and 256 will become 0.

Revamp the qdio performance statistics and move them from procfs to debugfs using the seq_file interface. Since the statistics are not intended for the general user the removal of /proc/qdio_perf should not surprise anyone. The per device statistics are disabled by default, writing 1 to /<debugfs mountpoint>/qdio/<device bus ID>/statistics enables the statistics for the given device.

2009-12-31twl4030-irq.c: fix compiler warning due to raw-spinlock conversionLinus Torvalds1-2/+2
Commit 239007b844 ("genirq: Convert irq_desc.lock to raw_spinlock") seems to have missed this driver, leaving it to use the normal spin-lock functions for the irq descriptor lock, which is now a raw lock.

2009-12-31pci: avoid compiler warning in quirks.cLinus Torvalds1-1/+1
Introduced by commit 5b889bf23 ("PCI: Fix build if quirks are not enabled"), which made the pci_dev_reset_methods[] array static and 'const', but didn't then change the code to match, and use a const pointer when moving it to quirks.c. Trivially fixed by just adding the required 'const' to the iterator variable. Reported-by: Stephen Rothwell <sfr@canb.auug.org.au> Cc: Rafael J.
