* radeonfb: Disable new color expand acceleration unless explicitely enabledBenjamin Herrenschmidt2008-12-091-0/+6
| | | | | | | | | | | | | This new color expansion acceleration for radeonfb appears to trigger problems with X on VT switch and suspend/resume on some machines. It might be a problem in the VT layer or in X, but I haven't quite found it yet, so in the meantime, this disables the acceleration by default, reverting to 2.6.27 state. It can be enabled using the "accel_cexp" module parameter or fbdev argument. Signed-off-by: Benjamin Herrenschmidt <benh@kernel.crashing.org> Acked-by: David S.

* radeonfb: accelerate imageblit and other improvementsBenjamin Herrenschmidt2008-10-161-15/+7
| | | | | | | | | | | | | | | | | | | | | | | | | | Implement support for HW color expansion of 1bpp images, along with some improvements to the FIFO handling and other accel operations. The offset fixup code is now unnecessary as the fbcon core will call our set_par upon switch back from KD_GRAPHICS before anything else happens. I removed it as it would slow down accel operations. The fifo wait has been improved to avoid hitting the HW register as often, and the various accel ops are now performing better caching of register values. Overall, this improve accel performances. The imageblit acceleration does result in a small overall regression in performances on some machines (on the order of 5% on some x86), probably becaus the SW path provides a better bus utilisation, but I decided to ingnore that as the performances is still very good, and on the other hand, some machines such as some sparc64 get a 3 fold performance improvement.

* sysfs: add parameter "struct bin_attribute *" in .read/.write methods for ↵Zhang Rui2007-07-111-2/+6
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | sysfs binary attributes Well, first of all, I don't want to change so many files either. What I do: Adding a new parameter "struct bin_attribute *" in the .read/.write methods for the sysfs binary attributes. In fact, only the four lines change in fs/sysfs/bin.c and include/linux/sysfs.h do the real work. But I have to update all the files that use binary attributes to make them compatible with the new .read and .write methods. I'm not sure if I missed any. :( Why I do this: For a sysfs attribute, we can get a pointer pointing to the struct attribute in the .show/.store method, while we can't do this for the binary attributes. I don't know why this is different, but this does make it not so handy to use the binary attributes as the regular ones. So I think this patch is reasonable. :) Who benefits from it: The patch that exposes ACPI tables in sysfs requires such an improvement. All the table binary attributes share the same .read method. Parameter "struct bin_attribute *" is used to get the table signature and instance number which are used to distinguish different ACPI table binary attributes. Without this parameter, we need to offer different .read methods for different ACPI table binary attributes. This is impossible as there are various ACPI tables on different platforms, and we don't know what they are until they are loaded.

* sysfs: kill unnecessary attribute->ownerTejun Heo2007-07-111-2/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | sysfs is now completely out of driver/module lifetime game. After deletion, a sysfs node doesn't access anything outside sysfs proper, so there's no reason to hold onto the attribute owners. Note that often the wrong modules were accounted for as owners leading to accessing removed modules. This patch kills now unnecessary attribute->owner. Note that with this change, userland holding a sysfs node does not prevent the backing module from being unloaded.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | If you'll recall, over a year ago, I pointed out that the current Radeon driver erroneously returns -EINVAL for valid blanking codes, here is a link to that thread: http://lkml.org/lkml/2006/1/28/6 No other driver does this, and it confuses the X server into thinking that the device does not support blanking properly. I looked again and there is simply no reason for the Radeon driver to return -EINVAL for FB_BLANK_NORMAL. It claims it wants to do this in order to convince fbcon to blank in software, right here: if (fb_blank(info, blank)) fbcon_generic_blank(vc, info, blank); to software blank the screen. But it only causes that to happen in the FB_BLANK_NORMAL case. That makes no sense because the Radeon code does this: val |= CRTC_DISPLAY_DIS; in the FB_BLANK_NORMAL case so should be blanking the hardware, and there is therefore no reason to SW blank by returning -EINVAL.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Many IBM Thinkpad T4* models and some R* and X* with radeon video cards draw too much power when suspended to RAM, reducing drastically the battery lifetime. The solution is to enable suspend-to-D2 on these machines. They are whitelisted through their subsystem vendor/device ID. This fixes http://bugzilla.kernel.org/show_bug.cgi?id=3022 The patch introduces a framework to alter the pm_mode and reinit_func fields of the radeonfb_info structure based on a whitelist. This should facilitate future hardware-dependent workarounds. The workaround for the Samsung P35 that is already in the radeonfb code has been rewritten using this framework. The behavior can be overridden with module options: i) video=radeonfb:force_sleep=1 enable suspend-to-D2 also on non-whitelisted machines (useful for testing new notebook models), ii) video=radeonfb:ignore_devlist=1 Disable checking the whitelist and do not apply any workarounds.

* [PATCH] framebuffer: cmap-setting return valuesAlan Curry2006-03-271-3/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | A set of 3 small bugfixes, all of which are related to bogus return values of fb colormap-setting functions. First, fb_alloc_cmap returns -1 if memory allocation fails. This is a hard condition to reproduce since you'd have to be really low on memory, but from studying the contexts in which it is called, I think this function should be returning a negative errno, and the -1 will be seen as an EPERM. Switching it to -ENOMEM makes sense. Second, the store_cmap function which is called for writes to /sys/class/graphics/fb0/color_map returns 0 for success, but it should be returning the count of bytes written since its return value ends up in userspace as the result of the write() syscall. Third, radeonfb returns 1 instead of a negative errno when FBIOPUTCMAP is called with an oversized colormap. This is seen in userspace as a return value of 1 from the ioctl() syscall with errno left unchanged. A more useful return value would be -EINVAL.

* [PATCH] fbcon/fbdev: Move softcursor out of fbdev to fbconAntonino A. Daplas2005-11-071-1/+0
| | | | | | | | | | | | | | | | | | | | According to Jon Smirl, filling in the field fb_cursor with soft_cursor for drivers that do not support hardware cursors is redundant. The soft_cursor function is usable by all drivers because it is just a wrapper around fb_imageblit. And because soft_cursor is an fbcon-specific hook, the file is moved to the console directory. Thus, drivers that do not support hardware cursors can leave the fb_cursor field blank. For drivers that do, they can fill up this field with their own version. The end result is a smaller code size. And if the framebuffer console is not loaded, module/kernel size is also reduced because the soft_cursor module will also not be loaded.

* [RADEON]: Fix unaligned I/O port access during probe.David S. Miller2005-09-291-1/+1
| | | | | | | | | | The driver does a readl() on DEVICE_ID which is 2-byte aligned and 2-bytes in size. It's doing this read just to flush write buffers. Create IN16() and OUT16() macros, and use the former to do this I/O load. Signed-off-by: David S. Miller <davem@davemloft.net>

* [PATCH] radeonfb: Only request resources we needDaniel Burcaw2005-09-091-9/+20
| | | | | | | | | | | | | | | This patch changes radeon to request only resources 0 and 2 instead of all 3. This works around problems with some setups where BAR 1 (IO BAR) has not been assigned by the firmware since it's not used on the machine and the kernel fails to assign something to it due to the card being between a P2P bridge that was configured without an IO range at all.

* [PATCH] radeonfb: don't blow up VGA console on loadBenjamin Herrenschmidt2005-06-121-4/+3
| | | | | | | | | | | The current radeonfb memset's the framebuffer to 0 when loaded. This removes occasional artifacts but has the nasty side effect that if you load radeonfb without framebuffer console, you destroy the VGA text buffer, font, etc... radeon must not touch the framebuffer content when it doesn't "own" it.
