The `_TCx\u0027 suffixes should provide\nan idea where they are connected to a socket or SoC.\n\nTiger Lake and seemingly Alder Lake use the first 4 TC register\nsets only. Hence we keep only 4 respective TC ports for now.\n\nAlso, as any of the 3 Combo-PHYs (DP1..3) can be used as eDP, we\nmap that to the port, that is used with the first set of panel-\ncontrol lines. This should hopefully match most board designs.\n\nChange-Id: If9755fe8e1f9252e6e77e22fe910964ad3c3743b\nSigned-off-by: Nico Huber \u003cnico.huber@secunet.com\u003e\nReviewed-on: https://review.sourcearcade.org/c/libgfxinit/+/456\nReviewed-by: Angel Pons \u003cth3fanbus@gmail.com\u003e\nTested-by: Nico Huber \u003cnico.h@gmx.de\u003e\n" }, { "commit": "99200feaca080bf6f5c4072c38672ad928cd8e7d", "tree": "4e787e64146d7a7bef8c689887bdc841407194be", "parents": [ "960e239abb429da6f9c6718d12ffd5d649fa9892" ], "author": { "name": "Nico Huber", "email": "nico.huber@secunet.com", "time": "Tue Apr 14 16:37:45 2026 +0200" }, "committer": { "name": "Nico Huber", "email": "nico.h@gmx.de", "time": "Sat Jun 06 10:23:00 2026 +0000" }, "message": "gma pipe_setup: Replace helper function w/ assertions\n\nThe Scale() function was supposed to help with the proof but right now\n(w/ gnatprove 11.2) it doesn\u0027t.

With these\nworkarounds, the system no longer locks up after running gfx_test. Looks\nlike the hang does not happen when coreboot runs libgfxinit.\n\nSteps to reproduce the hang:\n- Boot Linux without loading i915.\n- Run gfx_test without the workarounds.\n- After gfx_test exits and the machine enters a low-power state,\n it will lock up.\n\nIf something keeps the CPU from getting into low-power states (e.g.\n`cat /dev/zero \u003e /dev/null`), the machine will not lock up. However,\nstopping the load task after gfx_test has run will result in a lock-up.\n\nChange-Id: I4cd64cf4c1e702dc05709adc345a976a4e3c1ded\nSigned-off-by: Angel Pons \u003cth3fanbus@gmail.com\u003e\nReviewed-on: https://review.coreboot.org/c/libgfxinit/+/46635\nReviewed-by: Nico Huber \u003cnico.h@gmx.de\u003e\n" }, { "commit": "bc0588e482b1320d5739900b00a45033f5b587f4", "tree": "7ff658d42b39c286fc60675472bc24e6697aeae9", "parents": [ "994971af45dc06d0064e1b1bfd1d3c27989f107d" ], "author": { "name": "Nico Huber", "email": "nico.huber@secunet.com", "time": "Tue Jul 21 12:17:19 2020 +0200" }, "committer": { "name": "Nico Huber", "email": "nico.h@gmx.de", "time": "Mon Dec 21 17:53:57 2020 +0000" }, "message": "gma: Export backlight control interface\n\nChange-Id: I5a157d7849124fd3b4cca8f9de1d605092fd3c5e\nSigned-off-by: Nico Huber \u003cnico.huber@secunet.com\u003e\nReviewed-on: https://review.coreboot.org/c/libgfxinit/+/43668\nTested-by: Nico Huber \u003cnico.h@gmx.de\u003e\nReviewed-by: Angel Pons \u003cth3fanbus@gmail.com\u003e\n" }, { "commit": "994971af45dc06d0064e1b1bfd1d3c27989f107d", "tree": "bc9704d04299c7307e7c929c62d16dcda18ee181", "parents": [ "dde0630af418e6a3c2cd391579df5cea7350095a" ], "author": { "name": "Michael Niewöhner", "email": "foss@mniewoehner.de", "time": "Sun Dec 20 15:44:13 2020 +0100" }, "committer": { "name": "Nico Huber", "email": "nico.h@gmx.de", "time": "Mon Dec 21 17:40:35 2020 +0000" }, "message": "gma: actually enable/disable backlight with new backlight control\n\nIn order to enable or disable the backlight on platforms with the new\nbacklight control, both enable bits in the PWM register and the\nPP_CONTROL register need to bet set.

This is because no one had performed the required\nFDI mPHY initialization that is described on the Haswell graphics PRMs.\nAdd it to libgfxinit alongside some code to disable bending CLKOUT_DP.\n\nEven with the FDI mPHY initialization in place, the garbage would still\nbe present on the VGA monitor. Digital interfaces were not affected.\nBy carefully dumping and comparing the display registers of a good and\na bad case, it was determinted that the fault was due to a mismatched\nlink width for FDI. The FDI link between the iGPU and the Lynxpoint PCH\ncan operate in either x1 or x2 width, depending on the bandwidth needs\nof the monitor on the PCH\u0027s VGA port. To drive a 1920x1080 VGA monitor,\nit is necessary to use both FDI lanes. Moreover, both ends of the link\nneed to be configured to use the same link width. However, the wrong\nlink width was assumed when configuring the display pipe, because\n`DP.Lane_Count` was used unconditionally instead of `FDI.Lane_Count`.\n\nAfter fixing both issues, gfx_test is able to light up a 1920x1080 VGA\nmonitor on the Asrock B85M Pro4 successfully, even after a S3 resume.\n\nChange-Id: Ieabe3b7f947be2ef488ddb57bfeae85fa055d360\nSigned-off-by: Angel Pons \u003cth3fanbus@gmail.com\u003e\nReviewed-on: https://review.coreboot.org/c/libgfxinit/+/41343\nTested-by: Nico Huber \u003cnico.h@gmx.de\u003e\nReviewed-by: Nico Huber \u003cnico.h@gmx.de\u003e\n" }, { "commit": "3f86b0b121ff5f07d5d1ab5c1b210ea92620bb30", "tree": "8bef2905e89040626ee649e5ae1f1f85c1488112", "parents": [ "c0db994900fe9dabff9efd1b7fc547288a68c6c0" ], "author": { "name": "Angel Pons", "email": "th3fanbus@gmail.com", "time": "Sat Jul 18 00:22:32 2020 +0200" }, "committer": { "name": "Nico Huber", "email": "nico.h@gmx.de", "time": "Sun Jul 19 17:38:39 2020 +0000" }, "message": "Move `PSR_Off` out of `Power_And_Clocks_Haswell`\n\nAllowing other platforms to use the Haswell-specific power and clocks\npackage precludes with\u0027ing other Haswell-specific units unless they are\nplaced under `haswell_shared` as well.
