RHEL Engineering is moving the tracking of its product development work on RHEL 6 through RHEL 9 to Red Hat Jira (issues.redhat.com). If you're a Red Hat customer, please continue to file support cases via the Red Hat customer portal. If you're not, please head to the "RHEL project" in Red Hat Jira and file new tickets here. Individual Bugzilla bugs in the statuses "NEW", "ASSIGNED", and "POST" are being migrated throughout September 2023. Bugs of Red Hat partners with an assigned Engineering Partner Manager (EPM) are migrated in late September as per pre-agreed dates. Bugs against components "kernel", "kernel-rt", and "kpatch" are only migrated if still in "NEW" or "ASSIGNED". If you cannot log in to RH Jira, please consult article #7032570. That failing, please send an e-mail to the RH Jira admins at rh-issues@redhat.com to troubleshoot your issue as a user management inquiry. The email creates a ServiceNow ticket with Red Hat. Individual Bugzilla bugs that are migrated will be moved to status "CLOSED", resolution "MIGRATED", and set with "MigratedToJIRA" in "Keywords". The link to the successor Jira issue will be found under "Links", have a little "two-footprint" icon next to it, and direct you to the "RHEL project" in Red Hat Jira (issue links are of type "https://issues.redhat.com/browse/RHEL-XXXX", where "X" is a digit). This same link will be available in a blue banner at the top of the page informing you that that bug has been migrated.

Description smc_cert 2017-01-05 07:58:16 UTC 
Description of problem:
Atom E3940 (Apollo Lake) Intel HD Graphics 500 graphical resolution only up to 800x600 on RHEL 7.3 x86_64 UEFI mode but legacy mode up to 1024x768


The identical SUT got the correct output resolution and video type on Xrandr)
Ubuntu 16.04.1 Desktop (uEFI) (eDP1:1024x768)
Ubuntu 16.04.1 Desktop (uEFI) (HDMI:1920x1080)

RHEL 7.3 x86_64 (legacy) (default: 1024x768)
RHEL 7.3 x86_64 (uEFI) (default: 800x600)
(It shows "default" no matter plug the video connector on eDP1 or HDMI port)



Version-Release number of selected component (if applicable):
RHEL 7.3 x86_64 GA

How reproducible:
xrandr

Steps to Reproduce:
1.xrandr to check the  maximum value.
2.
3.

Actual results:
Current resolution only reach to 800x600

Expected results:
Min resolution should reach to to 1024x768

Would you be willing to lend us some of this hardware? I don't think we have any available.

As well, can you also do me a favor: add the parameter "drm.debug=0x6" to your kernel commandline, boot in UEFI mode and get me the output of

dmesg

(just dmesg is required, I don't need any of the other logs just yet)

Lyude,
  Good Day!
  Please find attached log "dmesg add parameter drm.debug=0x6.log" and is it ok that we setup the SUT which no support IPMI KVM console for you debugging remotely??

This would be just fine. This being said though it looks like this problem might not require any debugging to solve: the chipset this machine uses is apparently broxton, which I believe was (at the time of RHEL7.3) preliminary hardware. As confirmed by your dmesg:

[    3.641027] [drm] This hardware requires preliminary hardware support.
See CONFIG_DRM_I915_PRELIMINARY_HW_SUPPORT, and/or modparam preliminary_hw_support

This means that i915 won't enable itself on that chipset unless you add i915.preliminary_hw_support=1 to the kernel commandline. Can you check if things work somewhat better when you do that?

As for the difference in resolution: I think that's just the firmware having different default resolutions for UEFI vs. BIOS. The resolution just never updates to what it should be after booting since i915 disables itself.

I've also given a few more details regarding this to your partner manager.
