[Intel-gfx] Adding a i915 quirk (here: pipe A force quirk for testing purposes)?

[Sedat Dilek]

Hi,

>From [1]:
...
static struct intel_quirk intel_quirks[] = {
	/* HP Mini needs pipe A force quirk (LP: #322104) */
	{ 0x27ae, 0x103c, 0x361a, quirk_pipea_force },
...
}

Triple - which value is what?

00:02.0 VGA compatible controller [0300]: Intel Corporation 2nd
Generation Core Processor Family Integrated Graphics Controller
[8086:0116] (rev 09) (prog-if 00 [VGA controller])
        Subsystem: Samsung Electronics Co Ltd Device [144d:c0c7]
        Control: I/O+ Mem+ BusMaster+ SpecCycle- MemWINV- VGASnoop-
ParErr- Stepping- SERR- FastB2B- DisINTx+
        Status: Cap+ 66MHz- UDF- FastB2B+ ParErr- DEVSEL=fast >TAbort-
<TAbort- <MAbort- >SERR- <PERR- INTx-
        Latency: 0
        Interrupt: pin A routed to IRQ 49
        Region 0: Memory at f0000000 (64-bit, non-prefetchable) [size=4M]
        Region 2: Memory at e0000000 (64-bit, prefetchable) [size=256M]
        Region 4: I/O ports at 3000 [size=64]
        Expansion ROM at <unassigned> [disabled]
        Capabilities: <access denied>
        Kernel driver in use: i915

$ dmesg | egrep -i 'drm|i915' | grep dump_device_info
[   15.242823] [drm:i915_dump_device_info], i915 device info: gen=6,
pciid=0x0116 flags=is_mobile,need_gfx_hws,has_force_wake,has_fbc,has_hotplug,has_bsd_ring,has_blt_ring,has_llc,

OK, 0x0116 is the PCI-ID.

Seen also here...
Intel Corporation 2nd Generation Core Processor Family Integrated
Graphics Controller [8086:0116] (rev 09)

The two other values are from this line?

Subsystem: Samsung Electronics Co Ltd Device [144d:c0c7]

If so, what is what in triple :-)?

Thanks in advance.
