https://bugzilla.kernel.org/show_bug.cgi?id=49351 --- Comment #8 from Igor Murzov <e-mail@xxxxxxx> 2012-10-23 15:44:39 --- Created an attachment (id=84451) --> (https://bugzilla.kernel.org/attachment.cgi?id=84451) dmesg output for v3.7.0-rc2+ This dmesg output was produced with following changes: ---------------------------------------------- static int radeon_atpx_verify_interface(struct radeon_atpx *atpx) { union acpi_object *info; struct atpx_verify_interface output; size_t size; int err = 0; printk("*\n"); info = radeon_atpx_call(atpx->handle, ATPX_FUNCTION_VERIFY_INTERFACE, NULL); if (!info) return -EIO; printk("**\n"); memset(&output, 0, sizeof(output)); size = *(u16 *) info->buffer.pointer; if (size < 8) { printk("ATPX buffer is too small: %zu\n", size); err = -EINVAL; goto out; } printk("***\n"); size = min(sizeof(output), size); memcpy(&output, info->buffer.pointer, size); /* TODO: check version? */ printk("ATPX version %u\n", output.version); printk("****\n"); radeon_atpx_parse_functions(&atpx->functions, output.function_bits); out: kfree(info); return err; } ---------------------------------------------- And there is only one asterisk in the log: ---------------------------------------------- [ 11.199661] vga_switcheroo: enabled [ 11.199747] * ---------------------------------------------- So it is clear that some error is encountered in radeon_atpx_call(atpx->handle, ATPX_FUNCTION_VERIFY_INTERFACE, NULL); That explains why there is no "ATPX function mask" message in the log. -- Configure bugmail: https://bugzilla.kernel.org/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are watching the assignee of the bug. _______________________________________________ dri-devel mailing list dri-devel@xxxxxxxxxxxxxxxxxxxxx http://lists.freedesktop.org/mailman/listinfo/dri-devel
