parport: Use the PCI IRQ if offered

2009-04-07T15:44:06Z

PCI parallel port devices can IRQ share so we should stop them hogging the line and making a mess on modern PC systems. We know the sharing side works as the PCMCIA driver has shared the parallel port IRQ for some time. Signed-off-by: Alan Cox Signed-off-by: Linus Torvalds

parport->dev driver model support

2007-05-08T18:15:05Z

Currently a parport_driver can't get a handle on the device node for the underlying parport (PNPACPI, PCI, etc). That prevents correct placement of sysfs child nodes, which can affect things like power management. This patch adds a field to "struct parport" pointing to that device node, and updates non-legacy port drivers to initialize that device pointer. That field replaces the analagous PCI-only support in parport_pc.

[PATCH] parport: DEBUG_PARPORT build fix

2006-01-06T16:33:57Z

Add missing "struct" keyword preventing compilation with DEBUG_PARPORT defined. Also add some "const". Signed-off-by: Marko Kohtala Signed-off-by: Andrew Morton Signed-off-by: Linus Torvalds

[PATCH] broken cast in parport_pc

2005-12-12T16:57:45Z

Spotted by a Fedora user. Compiling with DEBUG_PARPORT set fails due to the broken cast. Just remove it. Signed-off-by: Dave Jones Signed-off-by: Andrew Morton Signed-off-by: Linus Torvalds

[PATCH] VIA8231 support for parallel port driver

2004-11-07T12:06:20Z

This patch allows the kernel to configure port's mode without help of BIOS. It is needed on my machine because its firmware simply ignores the parallel port leaving in unidirectional SPP mode. Notes on usage: To configure the port you need to: - if parport_pc driver is compiled as a module: specify parport_pc init_mode=[spp|ps2|epp|ecp|ecpepp] in /etc/modules file (for Debian Linux). - if the driver is linked statically with the kernel: specify parport_init_mode=[spp|ps2|epp|ecp|ecpepp] in kernel's arguments. This patch is intended for use primarily on Pegasos machines but it will work on any computer with VIA8231 south bridge. In this case it will override BIOS setting if you tell the driver to configure the port. BIOS setting will be honored if you omit init_mode parameter. Technical details: 1. On Pegasos standard port settings (set by OpenFirmware) are: IRQ=7, DMA=3, base address=0x3BC, mode is unidirectional SPP. 2. The patch changes only port mode, all other settings are preserved. So if you have a PC with VIA8231 and use driver to configure the port you'll still be able to change IRQ, DMA and base address in BIOS and these settings will be kept. 3. One exclusion: if you tell the driver to turn on EPP mode (specify epp or ecpepp value) and if default base address is 0x3BC (this is the case on Pegasos) the port will be moved to 0x378. EPP port can't have 0x3BC as the base. Known problems: 1. ECP+EPP mode is strange, it doesn't work even on several PC's i tested with Linux. ECP mode is detected and EPP is not. So if you get the same thing, it's not my fault. I just have no time to deal with it, current result is enough for me. 2. Not all devices work on Pegasos, i tried my Genuis-HR6 parallel port scanner and parallel ZIP drive and both of them don't work. ZIP drive is detected properly but then suddenly gets offline. Scanner does not answer any command at all. Without the patch the same thing happens. Obviously Pegasos has some more problems which are not discovered and not fixed yet.

[PATCH] parport: keep track of parport_pc ports

2004-03-03T03:07:29Z

parport_pc switched to keeping track of the ports it had created; in module_exit it uses the private list instead of messing with parport_enumerate(). Added compile fix for configs that have CONFIG_PARPORT_PC_FIFO turned off (from -mm).

[PATCH] Fix inlining failure (all GCCs) in parport

2004-02-04T02:34:15Z

From: Jan Hubicka GCC never inline extern inline function redefined by new body (because it is not clear what body one should choose) parport contains such duplicated functions for apparently no good reasons. Both copies differ slightly, not sure whether it is intentional or just garbage.
