From: Tomas Hruby Date: Tue, 29 Sep 2009 18:47:56 +0000 (+0000) Subject: Removed macros that depend on NOTIFY_FROM from servers and drivers. They X-Git-Tag: v3.1.5~68 X-Git-Url: http://zhaoyanbai.com/repos/rndc.html?a=commitdiff_plain;h=4dad30937b9af025bef03c2892998c13255213af;p=minix.git Removed macros that depend on NOTIFY_FROM from servers and drivers. They determine the information defined by these macros from the m_source field of the notify message. --- diff --git a/drivers/amddev/amddev.c b/drivers/amddev/amddev.c index 1491af553..e476551f4 100644 --- a/drivers/amddev/amddev.c +++ b/drivers/amddev/amddev.c @@ -21,6 +21,7 @@ Driver for the AMD Device Exclusion Vector (DEV) #include #include #include +#include #include /* Offsets from capability pointer */ @@ -78,13 +79,13 @@ int main(void) r= receive(ANY, &m); if (r != OK) panic(__FILE__, "receive failed", r); - switch(m.m_type) - { - case PROC_EVENT: - do_pm_notify(&m); - continue; - - case IOMMU_MAP: + if (is_notify(m.m_type)) { + if (_ENDPOINT_P(m.m_source) == PM_PROC_NR) { + do_pm_notify(&m); + continue; + } + } + else if (m.m_type == IOMMU_MAP) { r= do_add4pci(&m); m.m_type= r; send(m.m_source, &m); diff --git a/drivers/at_wini/at_wini.c b/drivers/at_wini/at_wini.c index c4da021ec..cb11f7c38 100644 --- a/drivers/at_wini/at_wini.c +++ b/drivers/at_wini/at_wini.c @@ -19,6 +19,7 @@ #include #include #include +#include #include #include #include @@ -1586,11 +1587,10 @@ struct command *cmd; /* Command block */ return(ERR); } - /* Schedule a wakeup call, some controllers are flaky.
