2014-09-22google/link, intel/wtm2: Do not include non-existent "hda.h" in i915.cPaul Menzel
Commit 75c83870 (azalia: Shrink boilerplate) [1] removed the header file `hda_verb.h`. This header is still included in the mainboard’s `i915.c`, causing the following build error, when native graphics initialization is enabled. CC mainboard/intel/wtm2/i915.ramstage.o src/mainboard/intel/wtm2/i915.c:34:22: fatal error: hda_verb.h: No such file or directory This was not caught, as native graphics initialization is not enabled for the build tests. It turns out that the array `mainboard_cim_verb_data` is not used in `src/mainboard/intel/wtm2/hda_verb.h`, so fix the problem by removing the inclusion.

2014-09-08Haswell/falco/peppy/slippy: continue to clean up FUI.Ronald G. Minnich
As a first step towards removing hardcodes from the FUI support, change the haswell call to i915_lightup to panel_lightup, and pass the intel_dp * as a parameter. Get rid of the scalar arguments and make them part of intel_dp. Get rid of file-scope variables and use the ones in the intel_dp struct. In falco, use functions that peppy uses. Drop slippy support for FUI, it's a dead board; if this is ok I'll remove the files next. And, incidentally, fix the broken RGBX constant and change it to BGRX.

2014-08-25intel/gma: Clarify code and use dedicated init for Google PeppyRonald G. Minnich
Peppy had some issues with FUI. We decided it was time to create peppy-specific gma.c and i915io.c files. Using yabel and the i915tool, we generated a replay attack, then interpolated against the slippy i915io.c to get something working. Also, in preparation for moving code out of the mainboard gma.c to generic driver code, we got rid of some hardcodes in the mainboard gma.c that have no business being there. The worst were the computation of gmch_[m,n] and it turns out that we had some long-standing bugs related to confusion about 'bpp'. I've killed the word bpp everywhere I could because there are at least 3 things that correspond to bpp. We now have framebuffer, pipe, and panel bpp. The names are long because I want to avoid all the mistakes we've all been making in the last year :-) Sadly, that means a lot of changes not just peppy-related, but they are simple and in a good cause. The test pattern generation is driven by a global variable in mainboard/peppy/gma.c. I've found in the past that it's very useful to have a function like this available, as one can activate it while using a jtag debugger: halt at the right place in ramstage, set the variable to 1, continue. It's not enough code to worry about always including. The last hard-codes for M and N registers are gone, and the function to set from generic intel_dp.c code works. To avoid screen trash on a dev mode boot, which we liked but nobody else did :-), we now take the time to put a pleasing background color that sort of doubles as a power LED. Rough timing is ramstage start is at 2.2, and dev setup is done at 3.3. These new platforms are depressingly slow to boot. Rom init alone is taking 1.9 seconds. 13 years ago it was 3 seconds from power on to bash prompt. These CPUs are at least 10x faster and take much longer to get going. Future work, once we get this through, is to move more functions to the intel driver, and combine the mainboard i915io.c into the mainboard gma.c. That separation only existed because i915io.c was generated by a tool, and it had lots of ugliness. Most ugliness is gone.

The new edid functions support converting the edid to an lb_framebuffer. Use them. Also, since panels seem to set bits per color instead of bits per pixel, just force the right value in the edid struct. Add helpful comment because people don't always believe we need to set the pallette. While we're at it, fix a problem that caused it to not compile.

coreboot tables are, unlike general system tables, a platform independent concept. Hence, use the same code for coreboot table generation on all platforms. lib/coreboot_tables.c is based on the x86 version of the file, because some important fixes were missed on the ARMv7 version lately.

2013-03-20link/graphics: Add support for EDIDRonald G. Minnich
This code is taken from an EDID reader written at Red Hat. The key function is int decode_edid(unsigned char *edid, int size, struct edid *out) Which takes a pointer to an EDID blob, and a size, and decodes it into a machine-independent format in out, which may be used for driving chipsets. The EDID blob might come for IO, or a compiled-in EDID BLOB, or CBFS. Also included are the changes needed to use the EDID code on Link.

2013-03-20link/graphics: New state machineRonald G. Minnich
This is a new state machine. It is more programmatic, in the case of auxio, and has much more symbolic naming, and very few "magic" numbers, except in the case of undocumented settings. As before, the 'pre-computed' IO ops are encoded in the iodefs table. A function, run, is passed and index into the table and runs the ops. A new operator, I, has been added. When the I operator is hit, run() returns the index of the next operator in the table. The i915lightup function runs the table. All the AUX channel ops have been removed from the table, however, and are now called as functions, using the previously committed auxio function. The iodefs table has been grouped into blocks of ops, which end in an I operator. As the lightup function progresses through startup, and the run() returns, the lightup function performs aux channel operations. This code is symbolic enough, I hope, that it will make haswell graphics bringup simpler. i915io.c, and the core of the code in i915lightup.c, were programatically generated, starting with IO logs from the DRM startup code in the kernel. It is possible to apply the tools that do this generation to newer IO logs from the kernel. Change-Id: I8a8e121dc0d9674f0c6a866343b28e179a1e3d8a Signed-off-by: Ronald G.

For full integration of FUI into coreboot, we need aux channel communcations. The intel_dp.c is a file taken from Linux and is used for aux channel comms. This file has been cut down to work with coreboot. For now it is associated with the link mainboard until we get a better handle on how this all fits together. This code is almost certainly usable on other platforms in the long term. But one step at a time. Change-Id: I7be4c56e0a7903f3901ac86e12b28f3bdc0f7947 Signed-off-by: Ronald G.
