Allow boards with GP-MMIO controllers to provide hooks to broadsheetfb in order to offload cmd/data writes and data reads instead of relying only on host based GPIO wiggling. Signed-off-by:

Add support for the color depth 15 on IGA1 and 30 on IGA1 and IGA2. To allow the usage of those the driver now refuses color depth that are totally off and otherwise the selection in viafb_check_var is used. Therefore the first call to this for the first framebuffer was delayed a bit. It only enables the new formats if they are requested exactly (viafb_bpp=15|30). As this is a new feature, no regressions are expected. The color depth 15 was successfully tested. Didn't get anything usable for 30 but that might be the programs fault. I would like to get some feedback whether it works as expected or not if somebody knows a program/configuration where it should. Signed-off-by:

This is a rewritten version of viafb_setcolreg. The hardware register writes were split up and moved to hw.c where they belong as this is really low level stuff. It was made dual fb aware. Furthermore viafb_setcmap was removed as the problem with 8bpp originated from a bug in writing multiple color registers at once. The removal of viafb_setcmap might introduce a small performance regression but its certainly better to receive the correct result a bit slower than a garbled picture fast. It should give us a working 8bpp mode and is more extensible than the old hardcoded code. No other regressions are expected but as the hardware might be a bit picky it might cause some regressions in 8bpp mode on some hardware although I doubt that. Signed-off-by:

Make color checking a bit more tolerant in what values it allows and more fine grained to later support 15 and 30 bits formats. It splits the filling of the color information in var to a seperate function and sets some color related values in var that where previously untouched. This could be a bug fix but at least I don't know any applications that was fooled by not correctly setting the fields in var. At least no regressions are expected. Signed-off-by:

Some code depended on IGA1_IGA2 which was never set (at least with the symbolic name). Remove this dead code although it might one day be useful to get a hint on how some things might work. However as this is dead it is likely full of bugs and would prevent a clean structure (as it has some very strange things). Dead code -> no regressions, at least if VIA doesn't do anything very ugly.

This patch splits color mode setting up in seperate functions. Some hardware initialization that was previously mixed with it is moved to viafb_setmode. As are the calls to the newly created function. This is yet another little step towards controlling each IGA on its own. As this patch really aims too mimic the old behaviour no regressions are expected. However I noticed that 8bpp (or 6bpp?) seems actually a bit broken before and after the patch. Signed-off-by:

Refuse to work if wrong parameters are given. This should improve the user experience as it will be clear that something is wrong and not silently ignored. Signed-off-by:

This patch is an attempt to make viafb_set_par work correctly with more than one framebuffer. As modesetting is not (yet/easily) possible for each individual IGA it uses the (normally to be avoided) global variables viafbinfo{,1} to ensure that each function is called with the correct values. This patch (finally) allows usable dual framebuffer setups and should not affect non dual fb ones. It works in some (most?) configurations as sometimes the driver still gets device connections wrong. It can be worth to try the devices in reverse order (in viafb_active_dev). The user experience is still not very nice as: - on the second fb you'll normally have a garbled picture as long as no application draws to it goal: auto on/off devices depending on reference counting - as the whole machinery is always done you can see mode changes also in an unaffected framebuffer goal: split modesetting up for each individual IGA Signed-off-by: -

Set always the correct video address. Especially do panning right on multiple IGAs. This should have no effect on single monitor mode (no SAMM, no dual fb). For SAMM without dual fb this might break something as I really cannot image what we are supposed to do for different resolutions with a single framebuffer as we can't get data out of nowhere (no, they are not set up in something one would call "expanded"). Previously I got for that funny colored pictures as the second IGA pointed to video memory that was never written to. After the patch it'll work as cloning if the first and second mode are identical (this was working already without SAMM). Finally for dual fb this should push us a step in the right direction.

This patch reorders the initialization for dual framebuffer mode to not ignore the settings for the first mode. Previously they were overwritten with the settings for the second one before they were applied. This should have no effect on non dual framebuffer mode and do what the user intended (initalization to desired modes) in dual framebuffer mode. Signed-off-by:

Remove some unused variables, move some dvi code around and store the detected maximum resolution for later use. The vertical resolution is handled as the old code did it but I hope it can be read from the hardware some day. No runtime change expected. Signed-off-by:

This is the first step to remove an artificial global index that was used in two ways: 1. As a pseudo index in the mode table. Pseudo as you had to search through the table to find the referenced entry. This was replaced by using a pointer to the entry. 2. As a shortcut to compare a combination of horizontal and vertical resolution at the same time. This was replaced by a "(hres<<16) | vres" which is good enough for now and the near future. If vres or hres become greater than 2^16 this might indeed cause problems but this solution allows to split this indexing mess up without the requirement to do even more code changes. This is a big change that will allow more clean ups. It should be a bit faster but that is probably not relevant for normal operation. No regressions expected but as this is a relatively big step heavy testing is appreciated. Signed-off-by:

Add generic implementations of the old and really old uname system calls. Note that sh only implements sys_olduname but not sys_oldolduname, but I'm not going to bother with another ifdef for that special case. m32r implemented an old uname but never wired it up, so kill it, too. Signed-off-by:

On an architecture that supports 32-bit compat we need to override the reported machine in uname with the 32-bit value. Instead of doing this separately in every architecture introduce a COMPAT_UTS_MACHINE define in <asm/compat.h> and apply it directly in sys_newuname(). Signed-off-by:

Add a generic implementation of the ipc demultiplexer syscall. Except for s390 and sparc64 all implementations of the sys_ipc are nearly identical. There are slight differences in the types of the parameters, where mips and powerpc as the only 64-bit architectures with sys_ipc use unsigned long for the "third" argument as it gets casted to a pointer later, while it traditionally is an "int" like most other paramters. frv goes even further and uses unsigned long for all parameters execept for "ptr" which is a pointer type everywhere. The change from int to unsigned long for "third" and back to "int" for the others on frv should be fine due to the in-register calling conventions for syscalls (we already had a similar issue with the generic sys_ptrace), but I'd prefer to have the arch maintainers looks over this in details. Except for that h8300, m68k and m68knommu lack an impplementation of the semtimedop sub call which this patch adds, and various architectures have gets used - at least on i386 it seems superflous as the compat code on x86-64 and ia64 doesn't even bother to implement it.
