From e044d8f92f79db167bb7f9dfd0f317e3238d82d1 Mon Sep 17 00:00:00 2001 From: Lv Zheng Date: Mon, 26 Jan 2015 16:58:48 +0800 Subject: ACPI: Introduce acpi_unload_parent_table() usages in Linux kernel ACPICA has implemented acpi_unload_parent_table() which can exactly replace the acpi_get_id()/acpi_unload_table_id() implemented in Linux kernel. The acpi_unload_parent_table() has been unit tested in ACPICA simulation environment. This patch can also help to reduce the source code differences between Linux and ACPICA.

To unify the parsing functions, OSPMs like Linux need a new ACPI_ADDRESS64_ATTRIBUTE as their substructs, so they can extract the shared data. This patch also synchronizes the structure changes to the Linux kernel. The usages are searched by matching the following keywords: 1. acpi_resource_address 2. acpi_resource_extended_address 3.

The code to obtain the GPE dispatcher type from the Handler->original_flags is wrong: if (((Handler->original_flags & ACPI_GPE_DISPATCH_METHOD) || (Handler->original_flags & ACPI_GPE_DISPATCH_NOTIFY)) && ACPI_GPE_DISPATCH_NOTIFY is 0x03 and ACPI_GPE_DISPATCH_METHOD is 0x02, thus this statement is TRUE for the following dispatcher types: 0x01 (ACPI_GPE_DISPATCH_HANDLER): not expected 0x02 (ACPI_GPE_DISPATCH_METHOD): expected 0x03 (ACPI_GPE_DISPATCH_NOTIFY): expected There is no functional issue due to this because Handler->original_flags is only set in acpi_install_gpe_handler(), and an earlier checker has excluded the ACPI_GPE_DISPATCH_HANDLER: if ((gpe_event_info->Flags & ACPI_GPE_DISPATCH_MASK) == ACPI_GPE_DISPATCH_HANDLER) { Status = AE_ALREADY_EXISTS; goto free_and_exit; } ... Handler->original_flags = (u8) (gpe_event_info->Flags & (ACPI_GPE_XRUPT_TYPE_MASK | ACPI_GPE_DISPATCH_MASK)); We need to clean this up before modifying the GPE dispatcher type values. In order to prevent such issue from happening in the future, this patch introduces ACPI_GPE_DISPATCH_TYPE() macro to be used to obtain the GPE dispatcher types. Lv Zheng.

GPE should be disabled if the driver wants to switch to the GPE polling mode when a GPE storm condition is indicated and should be enabled if the driver wants to switch back to the GPE interrupt mode when all of the storm conditions are cleared. The conditions should be protected by the driver's specific lock. 2. GPE should be enabled if the driver has accepted more than one request and should be disabled if the driver has completed all of the requests. The request count should be protected by the driver's specific lock. 3. GPE should be cleared either when the driver is about to handle an edge triggered GPE or when the driver has completed to handle a level triggered GPE. The handling code should be protected by the driver's specific lock. Thus the GPE enabling/disabling/clearing operations are likely to be performed with the driver's specific lock held while we currently cannot do this. This is because: 1. We have the acpi_gbl_gpe_lock held before invoking the GPE driver's handler. Driver's specific lock is likely to be held inside of the handler, thus we can see some dead lock issues due to the reversed locking order or recursive locking. In order to solve such dead lock issues, we need to unlock the acpi_gbl_gpe_lock before invoking the handler. BZ 1100. 2. Since GPE disabling/enabling/clearing should be determined by the GPE driver's state machine, we shouldn't perform such operations inside of ACPICA for a GPE handler to mess up the driver's state machine. BZ 1101. Originally this patch includes a logic to flush GPE handlers, it is dropped due to the following reasons: 1. This is a different issue; 2. Linux OSL has fixed this by flushing SCI in acpi_os_wait_events_complete(). We will pick up this topic when the Linux OSL fix turns out to be not sufficient. Note that currently the internal operations and the acpi_gbl_gpe_lock are also used by ACPI_GPE_DISPATCH_METHOD and ACPI_GPE_DISPATCH_NOTIFY. In order not to introduce regressions, we add one ACPI_GPE_DISPATCH_RAW_HANDLER type to be distiguished from ACPI_GPE_DISPATCH_HANDLER. For which the acpi_gbl_gpe_lock is unlocked before invoking the GPE handler and the internal enabling/disabling operations are bypassed to allow drivers to perform them at a proper position using the GPE APIs and ACPI_GPE_DISPATCH_RAW_HANDLER users should invoke acpi_set_gpe() instead of acpi_enable_gpe()/acpi_disable_gpe() to bypass the internal GPE clearing code in acpi_enable_gpe(). Lv Zheng. Known issues: 1. Edge-triggered GPE lost for frequent enablings On some buggy silicon platforms, GPE enable line may not be directly wired to the GPE trigger line. In that case, when GPE enabling is frequently performed for edge-triggered GPEs, GPE status may stay set without being triggered. This patch may maginify this problem as it allows GPE enabling to be parallel performed during the process the GPEs are handled. This is an existing issue, because: 1. For task context: Current ACPI_GPE_DISPATCH_METHOD practices have proven that this isn't a real issue - we can re-enable edge-triggered GPE in a work queue where the GPE status bit might already be set. 2. For IRQ context: This can even happen when the GPE enabling occurs before returning from the GPE handler and after unlocking the GPE lock. Thus currently no code is included to protect this.
