2009-09-09PCI: pcie, aer: init struct aer_err_info for reuseHidetoshi Seto
In case of multiple errors, struct aer_err_info would be reused among all reported devices. So the info->status should be initialized before recycled. Otherwise error of one device might be reported as the error of another device. Also info->flags has similar problem on reporting TLP header.

2009-09-09PCI: pcie, aer: rework MASK macros in aerdrv_errprint.cHidetoshi Seto
Definitions of MASK macros in aerdrv_errprint.c are tricky and unsafe. For example, AER_AGENT_TRANSMITTER_MASK(_sev, _stat) does work like: static inline func(int _sev, int _stat) { if (_sev == AER_CORRECTABLE) return (_stat & (PCI_ERR_COR_REP_ROLL|PCI_ERR_COR_REP_TIMER)); else return (_stat & PCI_ERR_COR_REP_ROLL); } In case of else path here, for uncorrectable errors, testing bits in _stat by PCI_ERR_COR_* does not make sense because _stat should have only PCI_ERR_UNC_* bits originated in uncorrectable error status register. But at this time this is safe because uncorrectable error using bit position same to PCI_ERR_COR_REP_ROLL(= bit position 8) is not defined. Likewise, AER_AGENT_COMPLETER_MASK is always PCI_ERR_UNC_COMP_ABORT but it works because bit 15 of correctable error status is not defined. It means that these MASK macros will turn to be wrong once if new error is defined. (In fact, bit 15 of correctable is now defined in PCIe 2.1) This patch changes these MASK macros to be more strict, not to return PCI_ERR_COR_* bits for uncorrectable error status and vise versa.

2009-09-09PCI: pci-stub: add pci_stub.ids parameterTejun Heo
Add ids module parameter which allows specifying initial IDs for the pci-stub driver. When built into the kernel, pci-stub is linked before any real pci drivers and by setting up IDs from initialization it can prevent built-in drivers from attaching to specific devices.

2009-09-09PCI ASPM: support per direction l0s managementKenji Kaneshige
The L0s state can be managed separately for each direction (upstream direction and downstream direction) of the link. But in the current implementation, those are mixed up. With this patch, L0s for each direction are managed separately. To maintain three states (upstream direction L0s, downstream L0s and L1), 'aspm_support', 'aspm_enabled', 'aspm_capable', 'aspm_disable' and 'aspm_default' fields in struct pcie_link_state are changed to 3-bit from 2-bit. The 'latency' field is separated to two 'latency_up' and 'latency_dw' fields to maintain exit latencies for each direction of the link. For L0, 'latency_up.l0' and 'latency_dw.l0' are used to configure upstream direction L0s and downstream direction L0s respectively. For L1, larger value of 'latency_up.l1' and 'latency_dw.l1' is considered as L1 exit latency.

2009-09-09PCI ASPM: support partial aspm enablementKenji Kaneshige
In the current implementation, ASPM L0s/L1 is disabled for all links in the hierarchy if one of the link doesn't meet latency requirement. But we can partially enable ASPM L0s/L1 on sub-tree in the hierarchy. This patch allows partial L0s/L1 enablement in the hierarchy. And it also reduce the calculation cost of ASPM configuration very much. In the previous implementation, all links were enabled with the same state. With this patch, enabled state for each link is determined simply as follows (the 'requested' is from policy_to_aspm_state()). enabled = requested & (link->aspm_capable & link->aspm_disable) Acked-by: Shaohua Li <shaohua.li@intel.com> Signed-off-by: Kenji Kaneshige <kaneshige.kenji@jp.fujitsu.com> Signed-off-by: Jesse Barnes <jbarnes@virtuousgeek.org>
2009-09-09PCI ASPM: introduce capable flagKenji Kaneshige
Introduce 'aspm_capable' field to maintain the capable ASPM setting of the link. By the 'aspm_capable', we don't need to recheck latency every time ASPM policy is changed. Each bit in 'aspm_capable' is associated to ASPM state (L0S/L1). The bit is set if the associated ASPM state is supported by the link and it satisfies the latency requirement (i.e. exit latency < endpoint acceptable latency). The 'aspm_capable' is updated when - an endpoint device is added (boot time or hot-plug time) - an endpoint device is removed (hot-unplug time) - PCI power state is changed.

2009-09-09PCI/GPU: implement VGA arbitration on LinuxBenjamin Herrenschmidt
Background: Graphic devices are accessed through ranges in I/O or memory space. While most modern devices allow relocation of such ranges, some "Legacy" VGA devices implemented on PCI will typically have the same "hard-decoded" addresses as they did on ISA. For more details see "PCI Bus Binding to IEEE Std 1275-1994 Standard for Boot (Initialization Configuration) Firmware Revision 2.1" Section 7, Legacy Devices. The Resource Access Control (RAC) module inside the X server currently does the task of arbitration when more than one legacy device co-exists on the same machine. But the problem happens when these devices are trying to be accessed by different userspace clients (e.g. two server in parallel). Their address assignments conflict. Therefore an arbitration scheme _outside_ of the X server is needed to control the sharing of these resources. This document introduces the operation of the VGA arbiter implemented for Linux kernel.

Reinette Chatre reports a frozen system (with blinking keyboard LEDs) when switching from graphics mode to the text console, or when suspending (which does the same thing). With netconsole, the oops turned out to be BUG: unable to handle kernel NULL pointer dereference at 0000000000000084 IP: [<ffffffffa03ecaab>] i915_driver_irq_handler+0x26b/0xd20 [i915] and it's due to the i915_gem.c code doing drm_irq_uninstall() after having done i915_gem_idle(). And the i915_gem_idle() path will do i915_gem_idle() -> i915_gem_cleanup_ringbuffer() -> i915_gem_cleanup_hws() -> dev_priv->hw_status_page = NULL; but if an i915 interrupt comes in after this stage, it may want to access that hw_status_page, and gets the above NULL pointer dereference. And since the NULL pointer dereference happens from within an interrupt, and with the screen still in graphics mode, the common end result is simply a silently hung machine. Fix it by simply uninstalling the irq handler before idling rather than after.
