I'm curious about why the drm driver calls this card a RV370, while pciconf and the X server call it a RV380: pciconf: "RV380 RADEON X600 Series 265MB" X server: "ATI Technologies Inc RV380 [Radeon X600 (PCIE)]" drm driver: "ATI Radeon RV370 X600 Pro" Could it be that the drm driver has the wrong chip set or configuration for this PCI ID? -- Greg Rivers --=-11zqm2DltEAqTjQtloSC Content-Type: TEXT/X-PATCH; NAME=drm-rv370-test.patch; CHARSET=us-ascii Content-Transfer-Encoding: BASE64 Content-ID: <alpine.BSF.2.00.0903181749333.47320@roadkill.tharned.org> Content-Description: Content-Disposition: ATTACHMENT; FILENAME=drm-rv370-test.patch SW5kZXg6IGRldi9kcm0vYXRpX3BjaWdhcnQuYw0KPT09PT09PT09PT09PT09PT09PT09PT09PT09 PT09PT09PT09PT09PT09PT09PT09PT09PT09PT09PT09PT09PT09PQ0KLS0tIGRldi9kcm0vYXRp X3BjaWdhcnQuYwkocmV2aXNpb24gMTg5OTMzKQ0KKysrIGRldi9kcm0vYXRpX3BjaWdhcnQuYwko d29ya2luZyBjb3B5KQ0KQEAgLTgzLDcgKzgzLDcgQEANCiAJfQ0KIA0KIAlmbGFncyA9IEJVU19E TUFfTk9XQUlUIHwgQlVTX0RNQV9aRVJPOw0KLQlpZiAoZ2FydF9pbmZvLT5nYXJ0X3JlZ19pZiA9 PSBEUk1fQVRJX0dBUlRfSUdQKQ0KKy8qCWlmIChnYXJ0X2luZm8tPmdhcnRfcmVnX2lmID09IERS TV9BVElfR0FSVF9JR1ApICovDQogCSAgICBmbGFncyB8PSBCVVNfRE1BX05PQ0FDSEU7DQogCQ0K IAlyZXQgPSBidXNfZG1hbWVtX2FsbG9jKGRtYWgtPnRhZywgJmRtYWgtPnZhZGRyLCBmbGFncywg JmRtYWgtPm1hcCk7DQo= --=-11zqm2DltEAqTjQtloSC--
