These board families are now handled in the DRM subsystem where we can have reusable panel drivers and some other stuff. The PL111 there is now the driver used in the defconfig for Versatile and Nomadik so no need to keep this code around. There are a few minor machines in arch/arm/ such as mach-netx still using the old driver, so we need to keep the core fbdev driver around for some time. Signed-off-by:

A fallthrough in switch/case was introduced in f627caf5 ("fbdev: sm712fb: fix crashes and garbled display during DPMS modesetting"), due to my copy-paste error, which would cause the memory clock frequency for SM720 to be programmed to SM712. Since it only reprograms the clock to a different frequency, it's only a benign issue without visible side-effect, so it also evaded Sudip Mukherjee's code review and regression tests. scripts/checkpatch.pl also failed to discover the issue, possibly due to nested switch statements. This issue was found by Stephen Rothwell by building linux-next with -Wimplicit-fallthrough. Reported-by:

Loongson MIPS netbooks use 1024x600 LCD panels, which is the original target platform of this driver, but nearly all old x86 laptops have 1024x768. Lighting 768 panels using 600's timings would partially garble the display. Since it's not possible to distinguish them reliably, we change the default to 768, but keep 600 as-is on MIPS. Further, earlier laptops, such as IBM Thinkpad 240X, has a 800x600 LCD panel, this driver would probably garbled those display. As we don't have one for testing, the original behavior of the driver is kept as-is, but the problem has been documented is the comments. Signed-off-by:

In order to support the 1024x600 panel on Yeeloong Loongson MIPS laptop, the original 1024x768-16 table was modified to 1024x600-16, without leaving the original. It causes problem on x86 laptop as the 1024x768-16 support was still claimed but not working. Fix it by introducing the 1024x768-16 mode. Signed-off-by:

On a Thinkpad s30 (Pentium III / i440MX, Lynx3DM), blanking the display or starting the X server will crash and freeze the system, or garble the display. Experiments showed this problem can mostly be solved by adjusting the order of register writes. Also, sm712fb failed to consider the difference of clock frequency when unblanking the display, and programs the clock for SM712 to SM720. Fix them by adjusting the order of register writes, and adding an additional check for SM720 for programming the clock frequency. Signed-off-by:

On a Thinkpad s30 (Pentium III / i440MX, Lynx3DM), running fbtest or X will crash the machine instantly, because the VRAM/framebuffer is not mapped correctly. On SM712, the framebuffer starts at the beginning of address space, but SM720's framebuffer starts at the 1 MiB offset from the beginning. However, sm712fb fails to take this into account, as a result, writing to the framebuffer will destroy all the registers and kill the system immediately. Another problem is the driver assumes 8 MiB of VRAM for SM720, but some SM720 system, such as this IBM Thinkpad, only has 4 MiB of VRAM. Fix this problem by removing the hardcoded VRAM size, adding a function to query the amount of VRAM from register MCR76 on SM720, and adding proper framebuffer offset. Please note that the memory map may have additional problems on Big-Endian system, which is not available for testing by myself. But I highly suspect that the original code is also broken on Big-Endian machines for SM720, so at least we are not making the problem worse. More, the driver also assumed SM710/SM712 has 4 MiB of VRAM, but it has a 2 MiB version as well, and used in earlier laptops, such as IBM Thinkpad 240X, the driver would probably crash on them. I've never seen one of those machines and cannot fix it, but I have documented these problems in the comments. Signed-off-by:

When the machine is booted in VGA mode, loading sm712fb would cause a glitch of random pixels shown on the screen. To prevent it from happening, we first clear the entire framebuffer, and we also need to stop calling smtcfb_setmode() during initialization, the fbdev layer will call it for us later when it's ready.

On a Thinkpad s30 (Pentium III / i440MX, Lynx3DM), the amount of Video RAM is not detected correctly by the xf86-video-siliconmotion driver. This is because sm712fb overwrites the GPR71 Scratch Pad Register, which is set by BIOS on x86 and used to indicate amount of VRAM. Other Scratch Pad Registers, including GPR70/74/75, don't have the same side-effect, but overwriting to them is still questionable, as they are not related to modesetting. Stop writing to SR70/71/74/75 (a.k.a GPR70/71/74/75). Signed-off-by:

On a Thinkpad s30 (Pentium III / i440MX, Lynx3DM), rebooting with sm712fb framebuffer driver would cause the role of brightness up/down button to swap. Experiments showed the FPR30 register caused this behavior. Moreover, even if this register don't have side-effect on other systems, over- writing it is also highly questionable, since it was originally configurated by the motherboard manufacturer by hardwiring pull-down resistors to indicate the type of LCD panel. We should not mess with it. Stop writing to the SR30 (a.k.a FPR30) register. Signed-off-by:

On a Thinkpad s30 (Pentium III / i440MX, Lynx3DM), rebooting with sm712fb framebuffer driver would cause a white screen of death on the next POST, presumably the proper timings for the LCD panel was not reprogrammed properly by the BIOS. Experiments showed a few CRTC Scratch Registers, including CRT3D, CRT3E and CRT3F may be used internally by BIOS as some flags. CRT3B is a hardware testing register, we shouldn't mess with it. CRT3C has blanking signal and line compare control, which is not needed for this driver. Stop writing to CR3B-CR3F (a.k.a CRT3B-CRT3F) registers. Even if these registers don't have side-effect on other systems, writing to them is also highly questionable. Signed-off-by:

Rendering calls may be done simultaneously from the workqueue, dlfb_ops_write, dlfb_ops_ioctl, dlfb_ops_set_par and dlfb_dpy_deferred_io. The code is robust enough so that it won't crash on concurrent rendering. However, concurrent rendering may cause display corruption if the same pixel is simultaneously being rendered. In order to avoid this corruption, this patch adds a mutex around the rendering calls. Signed-off-by:

If a framebuffer device is used as a console, the rendering calls (copyarea, fillrect, imageblit) may be done with the console spinlock held. On udlfb, these function call dlfb_handle_damage that takes a blocking semaphore before acquiring an URB. In order to fix the bug, this patch changes the calls copyarea, fillrect and imageblit to offload USB work to a workqueue. A side effect of this patch is 3x improvement in console scrolling speed because the device doesn't have to be updated after each copyarea call. Signed-off-by:

On Falcon, Atari frame buffer initialization relies on preprogrammed register values. These register values are changed to blank the console. Hence when using kexec to boot into a new kernel while the console is blanked, the new kernel cannot determine the current video configuration, and the Atari frame buffer driver fails to initialize: atafb: phys_screen_base 6ce000 screen_len 4096 Fix this by doing a straight-forward conversion of the driver to a platform device driver, and adding a shutdown handler that unblanks the display.
