I sort of worried that we'd not print the table physical address like we have in acpidump output. but i guess we print out the root pointer and active [X|R]SDT in the top of DMESG, so I guess we do have that info available after all and don't really need to dump the XSDT here... -- -Len Brown Intel Open Source Technology Center On Wed, 12 Nov 2008, Zhang Rui wrote: > hi all, > > this is the patch set I made recently for ACPI table management > enhancement. > > Patch 01 creates the sysfs I/F for ACPI dynamic tables. > > Patch 02 introduces a new mechanism for ACPI inactive table management. > > Patch 03 initializes the inactive tables at boot time and builds sysfs > I/F for these tables. > > Patch 04 introduces ACPI_INACTIVE_TABLE_MANAGEMENT to make the inactive > table management configurable. > > here is the ACPI table sysfs I/F on my laptop after applying these > patches. > #tree /sys/firmware/acpi/tables/ > /sys/firmware/acpi/tables/ > |-- APIC > |-- ASF! > |-- DMAR > |-- DSDT > |-- FACP > |-- FACS > |-- HPET > |-- MCFG > |-- SLIC > |-- SSDT1 > |-- SSDT2 > |-- SSDT3 > |-- SSDT4 > |-- dynamic > | |-- SSDT5 > | |-- SSDT6 > | |-- SSDT7 > | `-- SSDT8 > `-- inactive > |-- APIC > |-- ASF! > |-- DMAR > |-- DSDT > |-- FACP > |-- FACS > |-- HPET > |-- MCFG > |-- RSDT > |-- SLIC > |-- SSDT1 > |-- SSDT2 > |-- SSDT3 > `-- SSDT4 > > 2 directories, 31 files > > Patch 05 and Patch 06 fix a suspend/hibernation bug for me. > I have a test box which suspends well, but always reboots instead of > resuming when pressing the power button. > I found that there are two FACS tables on this platform, > XSDT-->FADT1-->Xfacs------>FACS1 > |----->facs-----| > |->FACS2 > RSDT-->FADT2-->facs-----| > Linux uses XSDT on this platform and sets the waking vector in FACS1 > when suspending.
