drm/tidss: implement WA for AM65xx erratum i2000

2020-08-21T12:17:05+00:00

This patch implements WA for AM65xx erratum i2000, which causes YUV formats to show wrong colors. An earlier patch removed a partial WA: a8d9d7da1546349f18eb2d6b6b3a04bdeb38719d ("drm/tidss: remove AM65x PG1 YUV erratum code") The patch explains the reasoning for removal. The change in plans has been that it has become clear that there are and will be users for PG1 SoCs and as such it's good to implement the WA for PG1s. This patch adds the WA back so that it is only used on SR1.0 (which is the new name for PG1). The previous WA code didn't check the SoC revision, which this patch does.

drm/tidss: fix modeset init for DPI panels

2020-08-04T08:10:21+00:00

The connector type for DISPC's DPI videoport was set the LVDS instead of DPI. This causes any DPI panel setup to fail with tidss, making all DPI panels unusable. Fix this by using correct connector type.

drm/tidss: Replace HTTP links with HTTPS ones

2020-07-16T20:13:52+00:00

Rationale: Reduces attack surface on kernel devs opening the links for MITM as HTTPS traffic is much harder to manipulate. Deterministic algorithm: For each file: If not .svg: For each line: If doesn't contain `\bxmlns\b`: For each link, `\bhttp://[^# \t\r\n]*(?:\w|/)`: If neither `\bgnu\.org/license`, nor `\bmozilla\.org/MPL\b`: If both the HTTP and HTTPS versions return 200 OK and serve the same content: Replace HTTP with HTTPS.

drm/atomic-helper: reset vblank on crtc reset

2020-07-02T18:25:51+00:00

Only when vblanks are supported ofc. Some drivers do this already, but most unfortunately missed it. This opens up bugs after driver load, before the crtc is enabled for the first time. syzbot spotted this when loading vkms as a secondary output. Given how many drivers are buggy it's best to solve this once and for all in shared helper code. Aside from moving the few existing calls to drm_crtc_vblank_reset into helpers (i915 doesn't use helpers, so keeps its own) I think the regression risk is minimal: atomic helpers already rely on drivers calling drm_crtc_vblank_on/off correctly in their hooks when they support vblanks. And driver that's failing to handle vblanks after this is missing those calls already, and vblanks could only work by accident when enabling a CRTC for the first time right after boot. Big thanks to Tetsuo for helping track down what's going wrong here. There's only a few drivers which already had the necessary call and needed some updating: - komeda, atmel and tidss also needed to be changed to call __drm_atomic_helper_crtc_reset() intead of open coding it - tegra and msm even had it in the same place already, just code motion, and malidp already uses __drm_atomic_helper_crtc_reset(). - Laurent noticed that rcar-du and omap open-code their crtc reset and hence would actually be broken by this patch now. So fix them up by reusing the helpers, which brings the drm_crtc_vblank_reset() back. Only call left is in i915, which doesn't use drm_mode_config_reset, but has its own fastboot infrastructure. So that's the only case where we actually want this in the driver still. I've also reviewed all other drivers which set up vblank support with drm_vblank_init. After the previous patch fixing mxsfb all atomic drivers do call drm_crtc_vblank_on/off as they should, the remaining drivers are either legacy kms or legacy dri1 drivers, so not affected by this change to atomic helpers. v2: Use the drm_dev_has_vblank() helper. v3: Laurent pointed out that omap and rcar-du used drm_crtc_vblank_off instead of drm_crtc_vblank_reset. Adjust them too. v4: Laurent noticed that rcar-du and omap open-code their crtc reset and hence would actually be broken by this patch now. So fix them up by reusing the helpers, which brings the drm_crtc_vblank_reset() back. v5: also mention rcar-du and ompadrm in the proper commit message above (Laurent).

drm/tidss: remove AM65x PG1 YUV erratum code

2020-05-05T07:00:07+00:00

AM65x PG1 has a HW issue with YUV pixel formats, resulting in wrong colors on the screen. This issue is fixed in PG2 hardware. The driver currently has code to hide YUV pixel formats from the userspace. To support PG2, we would need to add code to detect the SoC version and hide the YUV formats based on that. However, as PG1 will be phased out and PG2 will be the main platform, a much simpler solution is just to drop the code in question. The downside is that the users will be able to use YUV formats on PG1, getting wrong colors on the screen. On the other hand, that may also be a plus, as the same applications will now work on PG1 and PG2, even if the colors are wrong on PG1.
