From 8316f33766a82907c694267ff911e45e256f09f9 Mon Sep 17 00:00:00 2001 From: David Flynn Date: Wed, 8 Dec 2010 16:10:21 +0000 Subject: drm/i915/dp: Fix I2C/EDID handling with active DisplayPort to DVI converter The DisplayPort standard (1.1a) states that: The I2C-over-AUX Reply field is valid only when Native AUX CH Reply field is AUX_ACK (00). When Native AUX CH Reply field is not 00, then, I2C-over-AUX Reply field must be 00 and be ignored. This fixes broken EDID reading when using an active DisplayPort to duallink DVI converter. If the AUX CH replier chooses to defer the transaction, a short read occurs and erroneous data is returned as the i2c reply due to a lack of length checking and failure to check for AUX ACK. As a result, broken EDIDs can look like: 0 1 2 3 4 5 6 7 8 9 a b c d e f 0123456789abcdef 00: bc bc bc ff bc bc bc ff bc bc bc ac bc bc bc 45 ???.???.???????E 10: bc bc bc 10 bc bc bc 34 bc bc bc ee bc bc bc 4c ???????4???????L 20: bc bc bc 50 bc bc bc 00 bc bc bc 40 bc bc bc 00 ???P???.???@???. 30: bc bc bc 01 bc bc bc 01 bc bc bc a0 bc bc bc 40 ???????????????@ 40: bc bc bc 00 bc bc bc 00 bc bc bc 00 bc bc bc 55 ???.???.???.???U 50: bc bc bc 35 bc bc bc 31 bc bc bc 20 bc bc bc fc ???5???1??? ???? 60: bc bc bc 4c bc bc bc 34 bc bc bc 46 bc bc bc 00 ???L???4???F???. 70: bc bc bc 38 bc bc bc 11 bc bc bc 20 bc bc bc 20 ???8??????? ??? 80: bc bc bc ff bc bc bc ff bc bc bc ff bc bc bc ff ???.???.???.???. ... which can lead to: [drm:drm_edid_block_valid] *ERROR* EDID checksum is invalid, remainder [drm:drm_edid_block_valid] *ERROR* Raw EDID: <3>30 30 30 30 30 30 30 32 38 32 30 32 63 63 31 61 000000028202cc1a <3>28 00 02 8c 00 00 00 00 18 00 00 00 00 00 00 00 (............... <3>20 4c 61 73 74 20 62 65 61 63 6f 6e 3a 20 33 32 Last beacon: 32 <3>32 30 6d 73 20 61 67 6f 46 00 05 8c 00 00 00 00 20ms agoF....... <3>36 00 00 00 00 00 00 00 00 0c 57 69 2d 46 69 20 6.........Wi-Fi <3>52 6f 75 74 65 72 01 08 82 84 8b 96 24 30 48 6c Router......$0Hl <3>03 01 01 06 02 00 00 2a 01 00 2f 01 00 32 04 0c .......*../..2.. <3>12 18 60 dd 09 00 10 18 02 00 00 01 00 00 18 00 ..`.............
