ACPI: Convert to new X86 CPU match macros

2020-03-24T20:30:50Z

The new macro set has a consistent namespace and uses C99 initializers instead of the grufty C89 ones. Rename the local macro wrapper to X86_MATCH for consistency. It stays for readability sake.

Going primarily by: https://en.wikipedia.org/wiki/List_of_Intel_Atom_microprocessors with additional information gleaned from other related pages; notably: - Bonnell shrink was called Saltwell - Moorefield is the Merriefield refresh which makes it Airmont The general naming scheme is: FAM6_ATOM_UARCH_SOCTYPE for i in `git grep -l FAM6_ATOM` ; do sed -i -e 's/ATOM_PINEVIEW/ATOM_BONNELL/g' \ -e 's/ATOM_LINCROFT/ATOM_BONNELL_MID/' \ -e 's/ATOM_PENWELL/ATOM_SALTWELL_MID/g' \ -e 's/ATOM_CLOVERVIEW/ATOM_SALTWELL_TABLET/g' \ -e 's/ATOM_CEDARVIEW/ATOM_SALTWELL/g' \ -e 's/ATOM_SILVERMONT1/ATOM_SILVERMONT/g' \ -e 's/ATOM_SILVERMONT2/ATOM_SILVERMONT_X/g' \ -e 's/ATOM_MERRIFIELD/ATOM_SILVERMONT_MID/g' \ -e 's/ATOM_MOOREFIELD/ATOM_AIRMONT_MID/g' \ -e 's/ATOM_DENVERTON/ATOM_GOLDMONT_X/g' \ -e 's/ATOM_GEMINI_LAKE/ATOM_GOLDMONT_PLUS/g' ${i} done Signed-off-by: Peter Zijlstra (Intel) Cc: Alexander Shishkin Cc: Arnaldo Carvalho de Melo Cc: Jiri Olsa Cc: Linus Torvalds Cc: Peter Zijlstra Cc: Stephane Eranian Cc: Thomas Gleixner Cc: Vince Weaver Cc: dave.hansen@linux.intel.com Cc: len.brown@intel.com Signed-off-by: Ingo Molnar

Now that we init the status field to ACPI_STA_DEFAULT rather then to 0, the workaround for acpi_match_device_ids() always returning -ENOENT when status is 0 is no longer needed. Signed-off-by: Hans de Goede Reviewed-by: Andy Shevchenko Signed-off-by: Rafael J. Wysocki

ACPI / x86: Extend KIOX000A quirk to cover all affected BIOS versions

2017-10-21T11:24:53Z

Recently produced GPD win devices have a new BIOS, research into the changes in this BIOS has found a ChangeLog which shows that the disabling of the KIOX000A node has been done starting with the 20170221 version. Unfortunately the GPD pocket uses the exact same DMI strings as the win and its BIOS was copy-pasted from the GPD win, so it has a disabled KIOX000A node which we should not enable, so we need to check for the exact BIOS date. This commit adds 2 extra entries to the always_present_ids quirk table with bios_date matches for the older also affected and the latest BIOS.

The GPD win BIOS dated 20170320 has disabled the accelerometer, the drivers sometimes cause crashes under Windows and this is how the manufacturer has solved this :| I see no other way to keep the accelerometer working under Windows then adding it to the always_present_ids array.

ACPI / x86: Add Dell Venue 11 Pro 7130 touchscreen to always_present_ids

2017-07-12T11:26:10Z

The _STA method of the Venue 11 Pro 7130 touchscreen has this ugliness: Method (_STA, 0, NotSerialized) // _STA: Status { If ((SDS1 & One) == One) { If (RST1 == Zero) { Return (0x0F) } ElseIf (RST2 == Zero) { RST2 = One TMRV = Timer } Else { Local0 = ((Timer - TMRV) / 0x2710) If (Local0 > TMRI) { RST2 = Zero RST1 = Zero } } } Else { Return (Zero) } } Whereby RST1 gets set by _SB.PCI0.GFX0.LCD.LCD1._ON, this means that after RST1 has been set first _STA must be called to set TIMER and then after enough time has elapsed _STA must be called twice more, once to clear RST1 and once to finally return 0xf before the touchscreen will show up. Which is just crazy. This commit adds an always_present_ids entry for the SYNA7500 touchscreen ACPI node, together with a DMI match for the Venue 11 Pro 7130, fixing the touchscreen not working on this device.
