2011-05-20sanitize <linux/prefetch.h> usageLinus Torvalds1-0/+1
Commit e66eed651fd1 ("list: remove prefetching from regular list iterators") removed the include of prefetch.h from list.h, which uncovered several cases that had apparently relied on that rather obscure header file dependency. So this fixes things up a bit, using grep -L linux/prefetch.h $(git grep -l '[^a-z_]prefetchw*(' -- '*.[ch]') grep -L 'prefetchw*(' $(git grep -l 'linux/prefetch.h' -- '*.[ch]') to guide us in finding files that either need <linux/prefetch.h> inclusion, or have it despite not needing it. There are more of them around (mostly network drivers), but this gets many core ones.

* fbmem: Further fbcon sanity checking fbmem: fix remove_conflicting_framebuffers races
2011-05-14Further fbcon sanity checkingBruno Prémont1-4/+4
This moves the if (num_registered_fb == FB_MAX) return -ENXIO; check _AFTER_ the call to do_remove_conflicting_framebuffers() as this would (now in a safe way) allow a native driver to replace the conflicting one even if all slots in registered_fb[] are taken. This also prevents unregistering a framebuffer that is no longer registered (vga16f will unregister at module unload time even if the frame buffer had been unregistered earlier due to being found conflicting).

2011-05-14fbmem: fix remove_conflicting_framebuffers racesLinus Torvalds1-49/+68
When a register_framebuffer() call results in us removing old conflicting framebuffers, the new registration_lock doesn't protect that situation. And we can't just add the same locking to the function, because these functions call each other: register_framebuffer() calls remove_conflicting_framebuffers, which in turn calls unregister_framebuffer for any conflicting entry. In order to fix it, this just creates wrapper functions around all three functions and makes the versions that actually do the work be called "do_xxx()", leaving just the wrapper that gets the lock and calls the worker function. So the rule becomes simply that "do_xxxx()" has to be called with the lock held, and now do_register_framebuffer() can just call do_remove_conflicting_framebuffers(), and that in turn can call _do_unregister_framebuffer(), and there is no deadlock, and we can hold the registration lock over the whole sequence, fixing the races. It also makes error cases simpler, and fixes one situation where we would return from unregister_framebuffer() without releasing the lock, pointed out by Bruno Prémont.

* fbmem: fbmem: make read/write/ioctl use the frame buffer at open time fbcon: add lifetime refcount to opened frame buffers
2011-05-12fbmem: make read/write/ioctl use the frame buffer at open timeLinus Torvalds1-16/+34
read/write/ioctl on a fbcon file descriptor has traditionally used the fbcon not when it was opened, but as it was at the time of the call. That makes no sense, but the lack of sense is much more obvious now that we properly ref-count the usage - it means that the ref-counting doesn't actually protect operations we do on the frame buffer. This changes it to look at the fb_info that we got at open time, but in order to avoid using a frame buffer long after it has been unregistered, we do verify that it is still current, and return -ENODEV if not.

2011-05-12fbcon: add lifetime refcount to opened frame buffersLinus Torvalds1-10/+46
This just adds the refcount and the new registration lock logic. It does not (for example) actually change the read/write/ioctl routines to actually use the frame buffer that was opened: those function still end up alway susing whatever the current frame buffer is at the time of the call. Without this, if something holds the frame buffer open over a framebuffer switch, the close() operation after the switch will access a fb_info that has been free'd by the unregistering of the old frame buffer. (The read/write/ioctl operations will normally not cause problems, because they will - illogically - pick up the new fbcon instead. But a switch that happens just as one of those is going on might see problems too, the window is just much smaller: one individual op rather than the whole open-close sequence.) This use-after-free is apparently fairly easily triggered by the Ubuntu 11.04 boot sequence.

This patch adds a config option to be compatible with X servers like OpenChrome. This is required as for example the X server does not handle things like disabled IGAs/PLLs resulting in a potential freeze on X startup. With this option disabled we can provide some nice features like power management and not reinitializing the hardware on every mode switch (taking long time, causing flickering).

2011-04-23viafb: reduce OLPC refresh a bitFlorian Tobias Schandinat3-2/+3
When allowing some PLL calculation we get a frequency that seems to be a bit higher than what the OLPC DCON likes resulting in a still readable but not so good image. We don't really know whether this is a problem with the calculation formula or the OLPC but as other displays seem to be happy with the other modes adjusting the OLPC refresh looks like the better thing. This patch prevents a regression when dynamic PLL calculation is allowed. Signed-off-by: Florian Tobias Schandinat <FlorianSchandinat@gmx.de>
2011-04-23viafb: fix OLPC XO 1.5 device connectionFlorian Tobias Schandinat1-0/+5
This patch fixes the devices connected on OLPC. The OLPC panel seems to be connected to DVP1 and LVDS2 for some reasons and if not both are handled correct the display does not work correct or not at all. This patch prevents regressions on the OLPC where it worked by accident but would break in future as the driver did not know the correct devices connected. This might also fix hardware scaling. Hopefully the OLPC is the only device with such a requirement but it will be certainly better to actually know what devices are actually connected and to not work by accident.

2011-04-15viafb: fix OLPC DCON refresh rateFlorian Tobias Schandinat2-3/+7
This patch fixes a regression introduced by fd3cc69848b7e1873e5f12bbcdd572b20277ecf3a "viafb: remove duplicated clock storage" caused by an incosistent mode which pretended to have a higher refresh rate than it actually had. The wrong refresh rate resulted in a calculated higher pixclock which the OLPC DCON could not handle. By reducing the refresh rate to 50Hz we get close to the old pixclock which makes the OLPC display usable again. Minor other adjustments are needed as 60Hz is assumed to be a safe value which is not true for OLPC DCON. This is no problem as we only support 1200x900 on the OLPC.

2011-03-31s3fb: fix Virge/GX2Ondrej Zary1-14/+34
Fix Virge/GX2 support in s3fb: - fix IDs: 86C357 is GX2, 86C359 is GX2+, 86C356 probably does not exist - add memory size detection - drive it the same way as Trio3D/2X The original IDs most likely came from S3 website which claims that: - 356 is Virge/GX2 with ID=8A10, driver included in Windows 2K, XP - 357 is Virge/GX2+ with ID=8A11, driver included in Windows ME - 359 is Virge/GX2+ with ID=8A12, driver included in Windows ME but: - google search for 86C356 only reveals references to Trio3D (probably because of a typo - Trio3D is 86C365) - my card is clearly marked as 86C357, Virge/GX2 and has ID=8A10 - there is no driver for IDs 8A11 and 8A12 in Windows ME - there is a driver for ID 8A10 in Windows ME that says it's GX2 (357) Tested with #9 Reality 334 (86C357 Virge/GX2, ID=0x8A10).
