RHEL4.8: Patch to support new HDMI Audio
Last modified: 2010-10-22 23:46:57 EDT
Description of problem: The latest release does not support some ATI cards' HDMI function. The below patch is to support more HDMI Audio for RHEL 4.8. The original patch has been accepted by ALSA. http://git.alsa-project.org/?p=alsa-kernel.git;a=blobdiff;f=sound/pci/hda/hda_intel.c;h=a73d6ca0a90655104c48b7ea50b4089815de5b70;hp=ef9f072b47fcc65749729d22fa8e1390c1f8a8de;hb=45fc3c4d9b7ab12798af43a73aea53eeecd16acf;hpb=96348852cf8ff5597a39e866838679b3a9a38947 --- sound/pci/azx/hda_intel.c.orig 2008-08-15 06:29:35.000000000 +0800 +++ sound/pci/azx/hda_intel.c 2008-08-15 06:30:03.000000000 +0800 @@ -1783,6 +1783,7 @@ { 0x1002, 0x793b, PCI_ANY_ID, PCI_ANY_ID, 0, 0, AZX_DRIVER_ATIHDMI }, /* ATI RS600 HDMI */ { 0x1002, 0x7919, PCI_ANY_ID, PCI_ANY_ID, 0, 0, AZX_DRIVER_ATIHDMI }, /* ATI RS690 HDMI */ { 0x1002, 0x960f, PCI_ANY_ID, PCI_ANY_ID, 0, 0, AZX_DRIVER_ATIHDMI }, /* ATI RS780 HDMI */ + { 0x1002, 0x970f, PCI_ANY_ID, PCI_ANY_ID, 0, 0, AZX_DRIVER_ATIHDMI }, /* ATI RS780 HDMI */ { 0x1002, 0xaa00, PCI_ANY_ID, PCI_ANY_ID, 0, 0, AZX_DRIVER_ATIHDMI }, /* ATI R600 HDMI */ { 0x1002, 0xaa08, PCI_ANY_ID, PCI_ANY_ID, 0, 0, AZX_DRIVER_ATIHDMI }, /* ATI RV630 HDMI */ { 0x1002, 0xaa10, PCI_ANY_ID, PCI_ANY_ID, 0, 0, AZX_DRIVER_ATIHDMI }, /* ATI RV610 HDMI */

Created attachment 315323 [details] The updated patch Hi RedHat friends, Please use the attached patch. it fixed the comments issue.
Requesting exception as this request was not received by the RHEL 4.8 request deadline.
Updating PM score.
Raising priority. This patch adds a list of currently shipping devices to the Alsa driver, allowing audio over HDMI.
Hi, what's the current status of this issue? Will this patch be added into RHEL 4.8? Thanks.
Hi Andiry, The the request to add this to RHEL4.8 has been approved but the patch still needs to be reviewed by our kernel team. I'll follow up with Joachim to see where we're at. This event sent from IssueTracker by emcnabb issue 215952
patch is now posted to rh-kernel list
Committed in 79.EL . RPMS are available at http://people.redhat.com/vgoyal/rhel4/
Andiry, Libin, Can you verify this was added correctly? Committed in 79.EL . RPMS are available at http://people.redhat.com/vgoyal/rhel4/ This event sent from IssueTracker by emcnabb issue 215952
Hi Evan, It's confirmed that the patch has been merged into kernel-2.6.9-79.EL. But due to lack of HW device and display driver support, we are NOT able to test it so far. Anyway, if it cannot work properly in the future, we'll create another BZ. Thanks for your help.
Hi Evan, After our internal test, unfortunately we found that the patch is merged falsely and need to be modified. In RHEL 4.7 (kernel 2.6.9-78), the hda drivers are put under directory sound/pci/azx. we backported the patch based on this kernel version. But in redhat's update to RHEL 4.8 (kernel 2.6.9-80), the hda drivers are moved to directory sound/pci/hda, which is used in latest upstream kernel. But you maintain the directory azx and hda at the same time, which is wrong. You can see files under these two folders are almost the same. The patch should be applied to the directory sound/pci/hda to make it work. Anyway, in order to resolve this issue, a update patch is required. Please check the attachment and apply it in the next kernek version.

Bhavna, this BZ is assigned to you. Can you circulate the updated patch for reviea and approval?
Russ, I have posted the patch. I will change the status of the bug from FAILS_QA to POST.
Is there any update to this patch, will it be included in the kernel for RHEL4.8 Beta?
Shane, This was posted for internal review and there was some discussion about the patch (some as recently as yesterday). Since the beta bits have already been built, this will not be included in the public beta but probably snapshot 1 or 2. We will let you know when it is included in one of our test kernels.
