Subject: [PATCH] nv46: Change mc subdev oclass from nv44 to nv4c
|
|
|
4882915 |
|
|
|
4882915 |
MSI interrupts appear to not work for nv46 based cards. Change the mc
|
|
|
4882915 |
subdev oclass for these cards from nv44 to nv4c, the nv4c mc code is
|
|
|
4882915 |
identical to the nv44 mc code except that it does not use msi
|
|
|
4882915 |
(it does not define a msi_rearm callback).
