Hugh Dickins found that characters in xterm were going missing and oft delayed. Being the curious type, he managed to associate this with the new high-precision vblank patches; disabling these he found, restored the orderliness of his characters. The oddness begins when one realised that Hugh was not using vblanks at all on his system (fvwm and some xterms). Instead, all he had to go on were warning of a pipe underrun, curiously enough at around 60Hz. He poked and found that in addition to the underrun warning, the hardware was flagging the start of a new frame, a vblank, which in turn was kicking off the pending vblank processing code. There is little we can do for the underruns on Hugh's machine, a Crestline [965GM], which must have its FIFO watermarks set to 8. However, we do not need to process the vblank if we know that they are disabled... Reported-by: NHugh Dickins <hughd@google.com> Signed-off-by: NChris Wilson <chris@chris-wilson.co.uk>

By setting the FB of a CRTC to NULL, we are turning off the CRTC (and so disable the unused encoders and connectors). As such we can simplify the later tests by making sure the set->mode is NULL. Setting the num_connectors to zero means that we do not need to loop over the unused connectors. All current usage appears correct, this only builds additional defense into the routine.

In drm_crtc_helper_set_config, we call drm_crtc_helper_set_mode which may return early and do no operation if the crtc is to be disabled. In this case we merrily swap to the new fb, discarding the old_fb believing that it has been cleaned up. However, due to the early return, the old_fb was not presented to the backend for correct reaping, and nor was the new one - which is about to be reaped via the drm_helper_disable_unused_functions(), leading to incorrect refcounting of the pinned objects.

The opregion is a shared memory region between ACPI and the graphics driver. As the ACPI mapping has been changed to cachable in commit 6d5bbf00, mapping the intel opregion non-cachable now fails.

Now BUILD_BUG_ON() can handle optimizable constants, we don't need MAYBE_BUILD_BUG_ON any more. Signed-off-by: NRusty Russell <rusty@rustcorp.com.au>
-
由 Rusty Russell 提交于
BUILD_BUG_ON used to use the optimizer to do code elimination or fail at link time; it was changed to first the size of a negative array (a nicer compile time error), then (in 8c87df45) to a bitfield. This forced us to change some non-constant cases to MAYBE_BUILD_BUG_ON(); as Jan points out in that commit, it didn't work as intended anyway. bitfields: needs a literal constant at parse time, and can't be put under "if (__builtin_constant_p(x))" for example. negative array: can handle anything, but if the compiler can't tell it's a constant, silently has no effect. link time: breaks link if the compiler can't determine the value, but the linker output is not usually as informative as a compiler error. If we use the negative-array-size method *and* the link time trick, we get the ability to use BUILD_BUG_ON() under __builtin_constant_p() branches, and maximal ability for the compiler to detect errors at build time. We also document it thoroughly. Signed-off-by: NRusty Russell <rusty@rustcorp.com.au> Cc: Jan Beulich <JBeulich@novell.com> Acked-by: NHollis Blanchard <hollisb@us.ibm.com>

Currently only drivers that are built as modules have their versions shown in /sys/module/<module_name>/version, but this information might also be useful for built-in drivers as well. This especially important for drivers that do not define any parameters - such drivers, if built-in, are completely invisible from userspace. This patch changes MODULE_VERSION() macro so that in case when we are compiling built-in module, version information is stored in a separate section. Kernel then uses this data to create 'version' sysfs attribute in the same fashion it creates attributes for module parameters.

Starting with SandyBridge (though possible with earlier hacked BIOSes), the BIOS may initialise the IGFX as secondary to a discrete GPU. Prior, it would simply disable the integrated GPU. So we adjust our PCI class mask to match any DISPLAY_CLASS device. In such a configuration, the IGFX is not a primary VGA controller and so should not take part in VGA arbitration, and the error return from vga_client_register() is expected.
