* IRQ: Maintain regs pointer globally rather than passing to IRQ handlersDavid Howells2006-10-05
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Maintain a per-CPU global "struct pt_regs *" variable which can be used instead of passing regs around manually through all ~1800 interrupt handlers in the Linux kernel. The regs pointer is used in few places, but it potentially costs both stack space and code to pass it around. On the FRV arch, removing the regs parameter from all the genirq function results in a 20% speed up of the IRQ exit path (ie: from leaving timer_interrupt() to leaving do_IRQ()). Where appropriate, an arch may override the generic storage facility and do something different with the variable. On FRV, for instance, the address is maintained in GR28 at all times inside the kernel as part of general exception handling. Having looked over the code, it appears that the parameter may be handed down through up to twenty or so layers of functions. Consider a USB character device attached to a USB hub, attached to a USB controller that posts its interrupts through a cascaded auxiliary interrupt controller. A character device driver may want to pass regs to the sysrq handler through the input layer which adds another few layers of parameter passing. I've build this code with allyesconfig for x86_64 and i386. I've runtested the main part of the code on FRV and i386, though I can't test most of the drivers. I've also done partial conversion for powerpc and MIPS - these at least compile with minimal configurations. This will affect all archs. Mostly the changes should be relatively easy. Take do_IRQ(), store the regs pointer at the beginning, saving the old one: struct pt_regs *old_regs = set_irq_regs(regs); And put the old one back at the end: set_irq_regs(old_regs); Don't pass regs through to generic_handle_irq() or __do_IRQ(). In timer_interrupt(), this sort of change will be necessary: - update_process_times(user_mode(regs)); - profile_tick(CPU_PROFILING, regs); + update_process_times(user_mode(get_irq_regs())); + profile_tick(CPU_PROFILING); I'd like to move update_process_times()'s use of get_irq_regs() into itself, except that i386, alone of the archs, uses something other than user_mode(). Some notes on the interrupt handling in the drivers: (*) input_dev() is now gone entirely. The regs pointer is no longer stored in the input_dev struct. (*) finish_unlinks() in drivers/usb/host/ohci-q.c needs checking. It does something different depending on whether it's been supplied with a regs pointer or not. (*) Various IRQ handler function pointers have been moved to type irq_handler_t.

* [PATCH] VT binding: Update fbcon to support bindingAntonino A. Daplas2006-06-26
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The control for binding/unbinding is moved from fbcon to the console layer. Thus the fbcon sysfs attributes, attach and detach, are also gone. 1. Add a notifier event that tells fbcon if a framebuffer driver has been unregistered. If no registered driver remains, fbcon will unregister itself from the console layer. 2. Replaced calls to give_up_console() with unregister_con_driver(). 3. Still use take_over_console() instead of register_con_driver() to maintain compatibility 4. Respect the parameter first_fb_vc and last_fb_vc instead of using 0 and MAX_NR_CONSOLES - 1. These parameters are settable by the user. 5. When fbcon is completely unbound from the console layer, fbcon will also release (iow, decrement module reference counts to zero) all fbdev drivers. In other words, a bind or unbind request from the console layer will propagate down to the framebuffer drivers. 6. If fbcon is not bound to the console, it will ignore all notifier events (except driver registration and unregistration) and all sysfs requests.

* [PATCH] Detaching fbcon: add capability to attach/detach fbconAntonino A. Daplas2006-06-26
| | | | | | | | | | | | | | | | | | | | | | | | Add the ability to detach and attach the framebuffer console to and from the vt layer. This is done by echo'ing any value to sysfs attributes located in class/graphics/fbcon. The two attributes are: attach - bind fbcon to the vt layer detach - unbind fbcon from the vt layer Once fbcon is detached from the vt layer, fbcon can be unloaded if compiled as a module. This feature is quite useful for developers who work on the framebuffer or console subsystem. This is also useful for users who want to go to text mode or graphics mode without having to reboot. Directly unloading the fbcon module is not possible because the vt layer increments the module reference count for all bound consoles. Detaching fbcon decrements the module reference count to zero so unloading becomes possible. Detaching fbcon may interfere with X and/or DRM.

* [PATCH] Detaching fbcon: sdd sysfs class device entry for fbconAntonino A. Daplas2006-06-26
| | | | | | | | | | | | | | | | In order for this feature to work, an interface will be needed. The most appropriate is sysfs. However, the framebuffer console has no sysfs entry yet. This will create a sysfs class device entry for fbcon under /sys/class/graphics. Add a class_device entry 'fbcon' under class 'graphics'. Console-specific attributes which where previously under class/graphics/fb[x] are moved to class/graphics/fbcon. These attributes, 'con_rotate' and 'con_rotate_all', are also renamed to 'rotate' and 'rotate_all' respectively.

* [PATCH] Detaching fbcon: fix vgacon to allow retaking of the consoleAntonino A. Daplas2006-06-26
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | One of the limitations of the framebuffer console system is its inablity to unload or detach itself from the console layer. And once it loads, it also locks in framebuffer drivers preventing their unload. Although the con2fbmap utility does provide a means to unload individual drivers, it requires that at least one framebuffer driver is loaded for use by fbcon. With this change, it is possible to detach fbcon from the console layer. If it is detached, it will reattach the boot console driver (which is permanently loaded) back to the console layer so the system can continue to work. As a consequence, fbcon will also decrement its reference count of individual framebuffer drivers, allowing all of these drivers to be unloaded even if fbcon is still loaded. Unless you use drivers that restores the display to text mode (rivafb and i810fb, for example), detaching fbcon does require assistance from userspace tools (ie, vbetools) for text mode to be restored completely. Without the help of these tools, fbcon will leave the VGA console corrupted. The methods that can be used will be described in Documentation/fb/fbcon.txt. Because the vt layer also increments the module reference count for each console driver, fbcon cannot be directly unloaded. It must be detached first prior to unload. Similarly, fbcon can be reattached to the console layer without having to reload the module. A nice feature if fbcon is compiled statically. Attaching and detaching fbcon is done via sysfs attributes. A class device entry for fbcon is created in /sys/class/graphics. The two attributes that controls this feature are detach and attach. Two other attributes that are piggybacked under /sys/class/graphics/fb[n] that are fbcon-specific, 'con_rotate' and 'con_rotate_all' are moved to fbcon. They are renamed as 'rotate' and 'rotate_all' respectively. Overall, this feature is a great help for developers working in the framebuffer or console layer. There is not need to continually reboot the kernel for every small change. It is also useful for regular users who wants to choose between a graphical console or a text console without having to reboot. Example usage for x86: /* start in text mode */ modprobe xxxfb modprobe fbcon /* graphical mode with fbcon using xxxfb */ echo 1 > /sys/class/graphics/fbcon/detach /* back to text mode, will produce corrupt display unless vbetool is used */ rmmod xxxfb modprobe yyyfb /* back to graphical mode with fbcon using yyyfb */ Before trying out this feature, please read Documentation/fb/fbcon.txt. This patch: In order for fbcon to detach itself from the console layer, vgacon, which is a boot console driver, must be fixed so it can retake the console multiple times, not just during init. The following needs to be done: - remove __init from the vgacon_startup, this is called again by take_over_console(). - vc->rows and vc->cols are set manually by vgacon during init. After init, vc_resize() can be used - make sure the scrollback_buffer is not reallocated Signed-off-by: Antonino Daplas <adaplas@pol.net> Signed-off-by: Andrew Morton <akpm@osdl.org> Signed-off-by: Linus Torvalds <torvalds@osdl.org>
* [PATCH] vgacon: make VGA_MAP_MEM take size, remove extra useBjorn Helgaas2006-06-22
| | | | | | | | | | | | | | | | | | | | | VGA_MAP_MEM translates to ioremap() on some architectures. It makes sense to do this to vga_vram_base, because we're going to access memory between vga_vram_base and vga_vram_end. But it doesn't really make sense to map starting at vga_vram_end, because we aren't going to access memory starting there. On ia64, which always has to be different, ioremapping vga_vram_end gives you something completely incompatible with ioremapped vga_vram_start, so vga_vram_size ends up being nonsense. As a bonus, we often know the size up front, so we can use ioremap() correctly, rather than giving it a zero size. Signed-off-by: Bjorn Helgaas <bjorn.helgaas@hp.com> Cc: "Antonino A.

The bug is triggered with e.g. mode 800x600, vxres 1024, vyres 8192, bpp 8, font dimensions 8x16, 8Mb video ram and FBINFO_HWACCEL_YWRAP set. If those conditions are met, scrolling is broken and garbage is permanently displayed at the bottom of the screen. No regression, no possible side effects. Definitely needed by cyblafb and probably needed by amifb.

* [PATCH] fbcon: don´t call set_par() in fbcon_init() if vc_mode == KD_GRAPHICSKnut Petersen2006-01-07
| | | | | | | | | | | | | | | | Nothing prevents a user to modprobe a framebuffer driver from e.g. the xterm prompt. As a result, the set_par() function of the driver will be called from fbcon_init(). This is fatal as a lot of X / framebuffer combinations are unable to recover from set_par() reprogramming the graphics controller in KD_GRAPHICS mode. It is also unnecessary as the set_par() function will be called during a switch to KD_TEXT anyway. Because of this no side effects are possible.

* [PATCH] Fix framebuffer console upside-down ywrap scrollingKnut Petersen2005-12-20
| | | | | | | | | | | | | | | | | | Whenever ywrap scrolling is selected together with 180 degree screen rotation, 2.6.15-rc6 and earlier versions are broken. fb_pan_display() expects non-negative yoffsets, but ud_update_start() calls it with yoffsets down to -(yres - font height). This patch transforms yoffset to the correct range 0 ... vyres-1. Some obviously unneeded parentheses are removed, too. Verified with cyblafb, should be applied before 2.6.15-final because it does fix the framebuffer rotation code introduced early in the 2.6.15 release cycle.

* [PATCH] fbdev: fix switch to KD_TEXT, enhanced versionKnut Petersen2005-12-13
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Every framebuffer driver relies on the assumption that the set_par() function of the driver is called before drawing functions and other functions dependent on the hardware state are executed. Whenever you switch from X to a framebuffer console for the very first time, there is a chance that a broken X system has _not_ set the mode to KD_GRAPHICS, thus the vt and framebuffer code executes a screen redraw and several other functions before a set_par() is executed. This is believed to be not a bug of linux but a bug of X/xdm. At least some X releases used by SuSE and Debian show this behaviour. There was a 2nd case, but that has been fixed by Antonino Daplas on 10-dec-2005. This patch allows drivers to set a flag to inform fbcon_switch() that they prefer a set_par() call on every console switch, working around the problems caused by the broken X releases. The flag will be used by the next release of cyblafb and might help other drivers that assume a hardware state different to the one used by X. As the default behaviour does not change, this patch should be acceptable to everybody. Signed-off-by: Knut Petersen <Knut_Petersen@t-online.de> Acked-by: "Antonino A.

| | | | | | | | | There is a bug in the complement_mask when you have a 512-character map.
