Re: [PATCH] add PCI ROMs to sysfs

[Jon Smirl <jonsmirl@yahoo.com>]

This is saying that my AGP bridge chip has a ROM right?

00:01.0 PCI bridge: Intel Corp. 82875P Processor to AGP Controller (rev
02) (prog-if 00 [Normal decode])
        Flags: bus master, 66Mhz, fast devsel, latency 64
        Bus: primary=00, secondary=01, subordinate=01, sec-latency=64
        I/O behind bridge: 0000d000-0000dfff
        Memory behind bridge: fe900000-feafffff
        Prefetchable memory behind bridge: f0000000-f7ffffff
        Expansion ROM at 0000d000 [disabled] [size=4K]
 
Each of my video controllers has one too:

01:00.0 VGA compatible controller: ATI Technologies Inc Radeon RV250 If
[Radeon 9000] (rev 01) (prog-if 00 [VGA])
        Subsystem: C.P. Technology Co. Ltd RV250 If [Radeon 9000 Pro
"Evil Commando"]
        Flags: stepping, 66Mhz, medium devsel, IRQ 177
        Memory at f4000000 (32-bit, prefetchable) [disabled]
[size=fea00000]
        I/O ports at de00 [disabled] [size=256]
        Memory at fe9e0000 (32-bit, non-prefetchable) [disabled]
[size=64K]
        Expansion ROM at 00020000 [disabled]
        Capabilities: <available only to root>
 
02:02.0 VGA compatible controller: ATI Technologies Inc Rage 128 PD/PRO
TMDS (prog-if 00 [VGA])
        Subsystem: ATI Technologies Inc Rage 128 AIW
        Flags: bus master, stepping, medium devsel, latency 64, IRQ 209
        Memory at f8000000 (32-bit, prefetchable) [size=fe800000]
        I/O ports at ce00 [size=256]
        Memory at fe7dc000 (32-bit, non-prefetchable) [size=16K]
        Expansion ROM at 00020000 [disabled]
        Capabilities: <available only to root>

Both of the video ROMs are at 00020000, won't they end up on top of
each other when enabled?

With the patch the video ROMs are in sysfs but the AGP bridge one is
not.
