2007-05-08fbdev: fbcon: check if mode can handle new screenAntonino A. Daplas1-0/+12
Check if the mode can properly display the screen. This will be needed by drivers where the capability is not constant with each mode. The function fb_set_var() will query fbcon the requirement, then it will query the driver (via a new hook fb_get_caps()) its capability. If the driver's capability cannot handle fbcon's requirement, then fb_set_var() will fail. For example, if a particular driver supports 2 modes where: mode1 = can only display 8x16 bitmaps mode2 = can display any bitmap then if current mode = mode2 and current font = 12x22 fbset <mode1> /* mode1 cannot handle 12x22 */ fbset will fail Signed-off-by: Antonino Daplas <adaplas@gmail.com> Signed-off-by: Andrew Morton <akpm@linux-foundation.org> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>

2007-05-08fbdev: advertise limitation of drawing engineAntonino A. Daplas1-0/+4
A few drivers are not capable of blitting rectangles of any dimension. vga16fb can only blit 8-pixel wide rectangles, while s3fb (in tileblitting mode) can only blit 8x16 rectangles. For example, loading a 12x22 font in vga16fb will result in a corrupt display. Advertise this limitation/capability in info->pixmap.blit_x and blit_y. These fields are 32-bit arrays (font max is 32x32 only), ie, if bit 7 is set, then width/height of 7+1 is supported.

The functions fb_read() and fb_write in fbmem.c assume that the framebuffer is in IO memory. However, we have 3 drivers (hecubafb, arcfb, and vfb) where the framebuffer is allocated from system RAM (via vmalloc). Using __raw_read/__raw_write (fb_readl/fb_writel) for these drivers is illegal, especially in other platforms. Create file read and write methods for these types of drivers.

2007-05-08x86, serial: convert legacy COM ports to platform devicesBjorn Helgaas2-32/+0
Make x86 COM ports into platform devices and don't probe for them if we have PNP. This prevents double discovery, where a device was found both by the legacy probe and by 8250_pnp, e.g., serial8250: ttyS0 at I/O 0x3f8 (irq = 4) is a 16550A 00:02: ttyS0 at I/O 0x3f8 (irq = 4) is a 16550A This also means IRDA devices without a UART PNP ID will no longer be claimed by the serial driver, which might require changes in IRDA drivers and administration. In addition to this patch, you may need to configure a setserial init script, e.g., /etc/init.d/setserial, so it doesn't poke legacy UART stuff back in. On Debian, "dpkg-reconfigure setserial" with the "kernel" option does this. To force the old legacy probe behavior even when we have PNPBIOS or ACPI, load the new legacy_serial module (or build 8250 static) with the "legacy_serial.force" option.

2007-05-08PNP: notice whether we have PNP devices (PNPBIOS or PNPACPI)Bjorn Helgaas1-0/+2
This series converts i386 and x86_64 legacy serial ports to be platform devices and prevents probing for them if we have PNP. This prevents double discovery, where a device was found both by the legacy probe and by 8250_pnp. This also prevents the serial driver from claiming IRDA devices (unless they have a UART PNP ID). The serial legacy probe sometimes assumed the wrong IRQ, so the user had to use "setserial" to fix it. Removing the need for setserial to make IRDA devices work seems good, but it does break some things. In particular, you may need to keep setserial from poking legacy UART stuff back in by doing something like "dpkg-reconfigure setserial" with the "kernel" option. Otherwise, the setserial-discovered "UART" will claim resources and prevent the IRDA driver from loading. This patch: If we can discover devices using PNP, we can skip some legacy probes. This flag ("pnp_platform_devices") indicates that PNPBIOS or PNPACPI is enabled and should tell us about builtin devices.

2007-05-08Add IRQF_IRQPOLL flag (common code)Bernhard Walle1-0/+4
irqpoll is broken on some architectures that don't use the IRQ 0 for the timer interrupt like IA64. This patch adds a IRQF_IRQPOLL flag. Each architecture is handled in a separate pach. As I left the irq == 0 as condition, this should not break existing architectures that use timer_irq == 0 and that I did't address with that patch (because I don't know). This patch: This patch adds a IRQF_IRQPOLL flag that the interrupt registration code could use for the interrupt it wants to use for IRQ polling. Because this must not be the timer interrupt, an additional flag was added instead of re-using the IRQF_TIMER constant. Until all architectures will have an IRQF_IRQPOLL interrupt, irq == 0 will stay as alternative as it should not break anything. Also, note_interrupt() is called on CPU-specific interrupts to be used as interrupt source for IRQ polling.

2007-05-08x86: create asm/cmpxchg.hJeff Dike7-418/+437
i386: Rearrange the cmpxchg code to allow atomic.h to get it without needing to include system.h. This kills warnings in the UML build from atomic.h about implicit declarations of cmpxchg symbols. The i386 build presumably isn't seeing this because a separate inclusion of system.h is covering it over. The cmpxchg stuff is moved to asm-i386/cmpxchg.h, with an include left in system.h for the benefit of generic code which expects cmpxchg there. Meanwhile, atomic.h includes cmpxchg.h. This causes no noticable damage to the i386 build. x86_64: Move cmpxchg into its own header. atomic.h already included system.h, so this is changed to include cmpxchg.h. This is purely cleanup - it's not fixing any warnings - so if the x86_64 system.h isn't considered as cleanup-worthy as i386, then this can be dropped. It causes no noticable damage to the x86_64 build. uml: The i386 and x86_64 cmpxchg patches require an asm-um/cmpxchg.h for the UML build.

dependency atomic_add_unless as inline. Remove system.h atomic.h circular dependency. I agree (with Andi Kleen) this typeof is not needed and more error prone. All the original atomic.h code that uses cmpxchg (which includes the atomic_add_unless) uses defines instead of inline functions, probably to circumvent a circular dependency between system.h and atomic.h on powerpc (which my patch addresses). Therefore, it makes sense to use inline functions that will provide type checking. atomic_add_unless as inline. Remove system.h atomic.h circular dependency. Digging into the FRV architecture shows me that it is also affected by such a circular dependency. Here is the diff applying this against the rest of my atomic.h patches. It applies over the atomic.h standardization patches.

2007-05-08atomic.h: i386 type safety fixMathieu Desnoyers1-3/+3
Remove an explicit cast to an integer type for the result returned by cmpxchg. It is not per se a problem on the i386 architecture, because sizeof(int) == sizeof(long), but whenever this code is cut'n'pasted to a accept passing an atomic64_t value as parameter to cmpxchg, xchg and add_unless, having 64 bits inputs casted to 32 bits.
